intake air temp control sensor

Where is this part located on a 2010 silverado 1500 v6?

92 Silverado K3500 7.4 L

Ok... Uneven and sometimes surging at Idle. Smells very rich at start up. It will run at low RPM, but when Accelerator is pressed, falls on its face. Now after about ten minutes of nursing it up the hill to work... it will begin to run normally. I have changed Mass Air flow sensor, O2 Sensor, Therm Temp sensor, Another sensor that runs the cooler fan, and Finally The Throttle position Sensor. Only ting left is the EGR valve and many have told me to just clean it out with Carb cleaner and re install., which I have done. I did learn that Throttle Position sensor should be Calibrated ...LOL How the Hell does one accomplish that?
Any Help? You guys have always been great.

Keyless remote entry

Remote entry not working. New remote won’t program. Replaced receiver unit under under dash but the two used ones would not program either. GM in all their wisdom has discontinued the receiver unit and has no replacement. Junk yard part only. Anyone else had to his problem?

02 silverado 1500 4.8

I cant figure my fuel pressure problem cant get it above 52 psi changed the pump.filter,regulator when key is turned on it jumps to 60 then immediately drops to 50 running its at 48-50 it jumps to 60 when I take the vacuum hose off regulator any suggestions

Vortec 7.4l fuel pressure

I have a 98 k2500 with a 454, 130,000 miles on it, and am having issues with random misfiring under a load. I have replaced the cap, rotor, plugs and wires, and the issue has come back after only a few hundred miles. I checked my fuel pressure, and it has a solid 60 psi at idle and with the key on/engine off, but when given some throttle, it drops to around 50 or lower, and doesn't seem to gain any psi as the throttle is held down. Is this an indication of a bad fuel pump or plugged fuel filter? I have both parts brand new, waiting to be installed if so, but don't want to put them on if I don't need to. Please help!


So all my gauges are wacked out on my truck, they work intermittently and then the needles will just drop. all or different ones at different times and then some will work again and some wont. Just depends on the day, also when I'm rolling down my driver window, my seat heater turns on. Is this all interconnected? maybe a computer problem? Driving me nuts!!!

Power steering issues with hydroboost

My 98 k2500 with vortec 7.4l has hydroboost brakes, and at idle and just above idle rpm, it has no power assist in the steering. Even in neutral while revving the motor. Once moving and rpm increases, the power assist returns. Is this a sign of a bad pump, or weak pump, and are the power steering pumps the same for hydroboost and non- hydroboost equipped vehicles? Would fluid contamination be a possible cause of this?


I have a 98 K 2500 with 8600+ GVWR and 454 Vortec motor, I'm in desperate need of front end alignment specs as I cannot find them anywhere on the internet. I have searched multiple combinations and looked for three days and I can no longer search the internet without losing my marbles! please help! thank you

2003 Silverado Leaking

2005 2500hd burnt wiring on neutral switch

Purchased a used camper and was pulling it home from town 2hrs from where I live. Lost lights on the way home, pulled over to check fuses blown my ign fuse in the fuse box under the hood. Check wires in steering column, nothing. Tried to jump starter didn't have enough juice. Stuck in bfe for 3 hrs so called a cab went to wally world because it was midnigh. Bought a battery installed it and it fired right up. Now I was short on fuses so I left a 20 amp in my 15 amp ign that kept blowing. Next day leaving a store go to crank it up nothing. .... tapped on starter fired right up. ... got home nothing ever since tested starter fine...power to the ign fuse, further investigation found a burnt plug on my transmission neutral safety switch. Ordered one from a local parts store for 180 bucks. .. get it and it's only a7 wire. ...mine a12 place would exchange since it was a dealer order bs.... so I decided to make the older clip work done the 7 wire plug didn't have the lil clips on the inside to add more wires to it. Starting pulling wire and noticed my red wire was melted and had melt wired a good 12 inches before the plug. Took plug apart and rewired the pins I could and use the one out of the new one as well. Metered all the wires make sure I put the right wires in the right pin slots. While installing the clips I noticed there were more melted wires further back so I checked and rewired any wires that looked problematic. Buttoned it all back up worked great for 1/2 day then same thing now Ive pulled the relay (which is good) and use a wire to basically bypass the switch. Is there a way to test the neutral safety switch in this situation? Now I turn the key on pop the hood jump the switch truck starts great however the gear indicator doesn't show when it's in park and will appear once truck is in motion. Are the odds are there are more burnt wiring that's causing this or could it be the switch? Any help would be greatly appreciated

Replace hydroboost with vacuum assist brakes

2wd transmission in 4wd

Can a 2wd 4L80E be adapted to work in place of a 4L60E in a 4wd truck/SUV like the 2wd th350 can be used in place of a 700R4 in a 4wd? I have done the 350/700r4 swap before but I have little knowledge of the newer transmission specs as far as output shaft length etc. I do know that the 80E has a bigger output shaft diameter than the 60E but I also have a t-case that came factory behind a 4L80E. Just don't have the 4wd transmission to compare. Any insight is appreciated and thanks in advance.

Re: Starts bit doesn't stay running

NEED HELP! 2005 Silverado Idle Problems

This is nothing new to my 2005 4.8L Silverado. Usually the problem came and went but now it's staying. As soon as I crank my truck the electric fan cuts on and idles rough. As soon as I start to drive and apply throttle the temperature gauge goes from min to max (typically stays at 210) and the engine almost dies and cuts off, almost like it has bad gas. When I idle in drive the truck revs up and begins to speed up. Have big plans for the truck so I need help as to what to check or replace! Thank you!

Transmission Codes 97 Silverado

A few days ago my wife left she called back said the speedo, tach, and PRND321 indicator lights wasn't working I told her to come back and I would look at it. When she got back she said when she went to pull out that it felt like the brake was stuck. I checked some fuses, fluid, ect found nothing obvious. I started the truck and everything was working I drove it and it drove fine. She went on to visit her family with no issues. It's been 4 days and approximately 200 miles later then last night the transmission slipped a little or the RPM's went higher than they should and it wasn't a smooth transition either going into 3rd or 4th. I had it hooked up to a computer and the codes were P0740, P0753, P0758, P0785, and P01860 all transmission codes. The transmission was rebuilt about 6 months ago but of course the warrant has expired. I know multiple transmission codes can mean it's the ignition but would that also cause or allow it to slip. Any ideas of what I should try to replace first?

constant power to coil

Have a 1995 K1500. I bought the truck with a bad engine and put a replacement engine in it. The truck started up but would not shut off until I disconnected the battery. The pink wire has power going to the coil all the time. I have unplugged the ignition switch to eliminate that and I still have power at the pink wire as soon as I hook up the battery. Not sure what direction to try next.

96 Z71 4x4 no power to rear wheels

Just bought this truck a couple weeks ago most of it seemed fine to the naked eye some cosmetic problems, door locks, muffler, and power steering pump, and some other minors. however i was doing some light 4x4 in our back lakes aria and thew truck shut off ue to over heating. let it cool down put some water and coolant in it and got it home. replaced radiator, top and bottom hoses, thermostat, and then found out the leak was the water pump. replaced and problem solved... however now when in drive reverse or any other gear that makes the vehicle move, it does not. maybe an inch or two. its almost like trying to drive with the e brake on. yes i have checked that, also changed tranny fluid and filter. I am at a loss and have put all the money i have into this and am missing out on work. is there anyone who can help me with this? again its a 96 Z71 silverado k1500 4x4 5.0 . is there a sensor that i missed. tried adjusting the shift cables and what not it wants to move but just wont do it.

Re: 98 Chevy 3/4 ton 4X4 hard to start

when you had the scanner on it did you look at the coolant temp and the fuel trims?

holding the gas pedal down to start, all the way down to the floor or just down enough to open the throttle?

all the way down while cranking is what is called "clear flood" it shuts off the fuel injectors to allow excess fuel to be cleared from the system. If that is what you have to do, then you have to look for why the engine is getting too much fuel.

If you push the gas pedal down to start but not all the way, then you are opening the throttle that may give it a little more fuel and air flow. You Idle air control solenoid my be dirty or stuck, your throttle body may be coked up. Maybe your fuel pressure is too low not allowing enough fuel to get through. Like a weak fuel pump taking too long to prime up the system. Or a bad check valve in the pump.

was the tool you hooked up a scanner or was it just a code reader?

89 stumped 89 chevy dies when put into reverse,drive and dies at a stop.ive replaced almost every sebsor under the hood (besides knock sensor cause nothing to do with the problem) replaced egr cleaned throttle body.plz help. Btw c1500 350 5.7


I will need year make, model, engine size, 2 or 4wd, cabin type (2 dr, 4dr, ext-cab...) to get a wiring diagram for your vehicle.

You may have a broken wire in the wire harness where the door opens and closes. I know you say you checked everything but you should check again. If you know somewhere that you can access a good scanner you might want to scan your vehicle for codes related to the body control module.

did you touch any wires to the body and short something out? Why did you change the speaker and what things did you unplug to change it?

If the door is still open, try putting the old speaker back is and see if maybe the speaker is not compatible.

intermitin ABS reading on a 2003 silerada 1500 2wd 4.8L

the truck came in with no ABS lights on the dash at all. But the truck was hopping at stops. I put the scanner on it and it said DS ABS sensor failure and PS weak. replaced both. Now on the test drive the ABS light came on rescanned and its reading DS intermitin. i've check the conections replaced the sensor with the best quality one and still its reading the same problem. Now the truck is not hopping at stops. Its braking fine... Just that light keeps coming on. I'm going to try the ground wire but I've never had this problem come up before and i don't want to keeprunning in circules. Any suggestions would help thanks.... Again there was no ABS light on to begin with and its a 2003 2wd 4.8L....I'm going to pull up the codes this mornibg and I will post them a little later....wELL THE CODE WAS c0227 If I remember right. I changed the front hub and the ABS light is now out but the chattering has come back but now only in the last 1 to 2 feet.... its more like a skipping. the only other thing i can think is the ECBM.

1993 chevy 1500 battery light on

Bought a t trailer wire harness put it on today. Where you just unplug the wires under the truck. Once I got done hooking it all up,tested everything.. when I went out there later and started it up my truck's battery light was on, the battery gage was almost in the red. I then turned on my blinker, once I did that my rpm and battery gage was pulsing to my blinker. I unhooked the wire harness and just plug everything back in like it was and it's still doing it. I had the battery checked about a month ago because my truck wouldn't start so I had it test. It was good and come to find out it was my alternator so I replaced that with a new one.. so anyone know what it could be

1997 chevy Silverado engine stalling

I have a 1997 Silverado starts just fine , idles just fine , as soon as you step on the brake to put it in gear it stalls , checked vacuum leaks , none. so while it was idling I was playing with the switchs , I noticed when you turn the head lights on it would stall, stepped on the brake with out trying to put it gear , and it stalled. removes the ABS relay it continued to idle, but had no power brakes. replaced the ABS relay. it stalled again when stepped on the brake. so it appears anything to with lights makes it stall. all fuses are good, all relays are good, wiring looks fine no burns or anything. in fact everything functions as it should , until you step on the brake or turn on the headlights. headlight switch is also new. don't know if this is relavent , but courtesy lights inside the cab has never worked . cluster lights works as they should.
anyone know what the problem , I would be grateful for the help on fixing this, Thanks in advance.

1994 Chevy K1500 Engine swap

What will I have to swap on the engine? Thanks for any help!

Re: 98 Chevy Silverado 1500 oil gauge misreading

the oil pressure gauge is not about your oil level. (unless the level gets too low and the pick up tube doesn't get to the oil) It measures the oil pressure that the pump is able to produce. Things that affect oil pressure are the weight of the oil used, temperature of the engine, engine rpm, clearances in the oil pump, the screen on the oil pick up, pressure relief valve, cam and crank bearing clearances.

thicker oil raises the oil pressure. higher engine rpm raises the oil pressure. tight clearances in the oil pump increases pressure. same with bearings. Just from the information you posted, it would seem your mechanic has made a logical call on replacing the engine or crank kit it.

I am sorry that I don't have any good news to give you. You could see the place where you bought the truck to see if they are willing to help you out. If it's a used car dealer, see if they would take it back on a trade. Or try to sell it and buy another vehicle.

Re: 1993 Chevy Silverado 350 engine temp gauge reads low

you would be looking at the dark green wire that goes from the temperature sender to the instrument cluster. Using an ohm meter, measure the resistance between the sender connector contact and the instrument cluster connector. (You would have to remove the cluster and unplug it) The cluster connector should be A to Z on the connector with the dark green wire being #R. However, most of the time, if the correct coolant sender is put in and the gauge is still reading cold, it's a bad gauge unit.

Re: Chevy Celebrity

you should use a scanner and look at the the crank sensor signal. it may have a weak signal until the rpms get up higher. Also the MAP sensor could be giving the wrong signal to the computer. (or may have a bad 5V reference signal to it) Start up fuel pressure might be low. Cycle the key on and off a few times to turn the 2 second prime to build up pressure and then try starting it. Measure the actual fuel pressure. it takes a little more pressure to start a cold engine than to keep it running or to start it when it is warm. You could look at the coolant temp sensor to see if it shows a good temperature reading.

when it won't start can you look to see if the fuel injector is spraying fuel while you are cranking?

Re: 1992 Chev silverado A/C

LOL Do I feel Like Dummy! I checked the cycling switch yesterday and found that it had worked loose. I took it off and firmly put it back on making sure the clip captured the tit on the switch. VIOLA !!!! A/C !!! I drove around half of last summer in AZ with the window rolled down. I'm such a procrastinator.... Thanks for the tip .... too funny. I want you all to share in a good laugh at me cause believe me, I'm laughing too.

Re: 1992 Chev Silverado Steering pump.

I had a leaking Power steering hose and I figured that at 147000 miles why not change the pump as well. Would it be a good idea to change the remainder of the hoses? They are cheap and easy to reach. Would a leaking low pressure hose contribute to this?

Thanks by the way

2011- Service Trailer Brake System

B0100 code, 2011, Silverado, 1500 4 x 4, 5.3L, Flex Fuel.
DIC shows message "Service Trailer Brake System".
A scan for codes shows seven events.
1. Short in D Squib Circuit. What and Where is D Squib? One of the Electronic Modules in the brake system some where?
2. FSC DTC What is FSC? Maybe...Front Sensor? Where?
3. MIL
4. History
5-7 repeats above.
These codes were manufacture specific to Chevy. No other codes.
No trailer is hooked up. Seems to show most frequently while backing out of the garage in cold weather. I can clear the code but it immediately registers again.
I noticed today that my battery seems to have a slow drain also. This was after 3 days of not driving it. Related...?

1996 chevy 5.7 miss fire only when it's cold

Ok i have a 1996 chevy silverado 5.7 vortec 4x4, when i start it, it runs fine for about 2 to 3 minutes then it starts to miss and back fire for about 15 to 20 min. and the check engine light comes on. I park, come back about 10 min later to leave and it does not want to start. After it does start it still misses and then it all stops after running it for about another 30~40 min. and the light goes off and runs fine

Re: transmission only has 1st and second gear

I would verify your fluid level and the color and smell of your transmission fluid. But it sounds like the trans is worn. Cold, when the fluid is thicker will let it catch for a while but when the fluid warms and thins it will just slip.

you should talk to a trans specialist

2003 Chevy grinding noise

I have a 2003 chevy silverado z71, my check engine light came on and now I hear a grinding noise when the truck is in gear. It has this noise going forward and in reverse (all the time moving slow or fast), however if I shift it to neutral while rolling the noise stops. Is this the tranny or the transfer case?

1994 c1500 ignition coil plug wire keeps burning out

I have a 1994 chevy 1500 with a 350 motor in it. It died the other day at a red light the engine died I put it in neutral, and re started it. It ran two minutes then died again. I was getting no spark and the rotor an distributor cap were fouled with corrosion so I replaced them. Still had no spark so and none coming from the ignition coil so I replaced that as well. Then my brain kicked in and I tested the plug wires, turns out the wire between the cap and coil was dead. The truck fired right up and ran for twenty minutes the died. I checked the brand bed wires and the one between the coil and cap is dead. I got a new set of plug wires thinking maybe it was a Defective set, ( have to love auto zone's lifetime warranty )
Put the new wire on and it would not crank at all checked the wire an it's has no connectivity using the ohms meter.
Is there a chance someone knows where my problem is?

temp problems

I have a 94 chevy pick up with a 5.7l and a 350hp. Shat would cause my temp to go to max when my truck is turned off?

Re: possible short? Please help

you should have a volt gauge not an amp gauge. having the gauge move when the blinkers are flashing is normal unless it is going to far to the discharge side.

you should use a dvom and check to see if the battery voltage is 13.8 to 14.2 with the engine running.

first things to check, I would verify that the alternator is charging correctly and check to see if there is a draw on the battery when the engine is not running.

1991 Chevy Cheyenne sudden knocking in engine

I parked my truck last night and all was good with the world. Got in it just now and tri to start it, it turned over then clicked. I checked the battery cables...loose, so I tightened. The truck then started and is now knocking in the drivers side. Checked oil, its fine. What could cause this sudden knocking? Possibly the oil pump?

Truck cuts on and off while driving

Hey guys- my 2010 silverado cuts on and off while I'm driving- it's like a complete shut off but my truck keeps going and doesn't stop- it jerks real hard. My friend put a computer on my car and no codes are coming up? Anyone know of this problem happening in other trucks or possibly have a solution?

94 z71 Brake light/acceleration issues

Guys I need some help.
I bought a 1994 z71 350 automatic. When the truck sits for a while the parking brake light comes on within the first minute or two of driving. Soon after the light comes on I start having a slight loss in acceration at low rpm. When it gets close to shifting, at higher rpm, I have a complete loss of acceration, almost like it shifts into neutral because it revs up. If I let off the gas it shifts and then the cycle repeats. Then my speedometer starts jumping around. Sometimes my service engine light comes on with it but sometimes it doesn't. The only other problem I have is that the brakes are pretty spongy and the temp gauge hardly budges (I am no expert so I don't know if a faulty temp sensor or such could be related). After it does this and then sits for a while it doesn't do it again. As long as I drive it at least every other day it will not do this. But more than that you can bet that light will come on. When I bought it I replaced the front pads, rotors, cv shafts, fuel filter, oil and filter, air filter, plugs, tps, and knock sensor. I also had a trans shop replace all the trans seals and gaskets plus filter. I'm out of ideas. Thanks in advance for the advice.


I just got chev 2008 silverado 1500 and airbag light is on but has not been deployed, it was in accident in rear bumper will I have to get new censor or can I get it reset or could it be something else?

Re: need a pro- 2001 silverado p0121

you're going to need to look at the freeze frame data for your code. once you see where it is acting up, you will need to drive with a scanner hooked up and graphing your dtat stream. See it there is a glitch in your TPS circuit. Make sure to watch toy TPS voltage when you let off the throttle. See if you can notice if the TPS voltage stays too high. Should drop below 1.0 volt when you let off the gas pedal. If there are any drop outs check you wiring to the TPS.

98' C2500 will not Crank

I am at the Hair pulling stage and I don't have much left! Please help!

I have a no crank situation with my 98' chevy 2500 5.7 vortec. It started right up yesterday; I drove to bank ran in and out, truck would not start. 30 minutes later it started. I then drove home, ran in grabbed something and it would not start again. 30 minutes later it started. I drove to store it would not restart, towed it home to my shop where it sits now. I have gone through all the usual steps of testing everything from the key up to the starter. Here is what I have so far:

1) Remote switch to starter and it cranks. Bench test starter not necessary at this point I believe.
2) multi meter to S post on starter, key to ignition position, meter shows 11.2 volts at S post, key off meter shows 0 volts.
3) swapped out starter relay with brand new one, no changes. Tested both sides of relay block(constant and key on) 12.9 volts.
4) Security system light does go out after 5 seconds, so that is not issue, I think?
5) adjusted neutral safety switch every which way, no change. tried to start in neutral, no change.

It would appear that from the key to the starter all the power is where it should be!???? What am I missing???

Many Thanks In Advance!!!!!!

2004 chevy silverado gauges not working

I have a 2000 chevy silverado and i did an engine swap from a 4.3L motor to a 5.3L. But the engine i installed its from a chevy 2004 and bu the time i was finished with my truck, i noticed that the gauges weren't working. I turned my truck on and none of the gauges weren't working not even the RPM. So i connected my computer scanner to see wat it was and as soon i plug my scanner on the PED connection, the gauges started working and i disconnect the scanner and it stopped working. I already cheked all the ground wires and i doubled check if i had missed a harness connection but everything was connected fine.. I already have like 3 weeks and i cant find a solution to fix the gauges.

Chevy Silverado ac belt knocking

I have an 03 silverado 5.3l v8. Ac problems. Last year, my compressor (I'm assuming) would cause my ac tensioner to knock and broke 2 belts. Assuming bad compressor, I left the belt of and dealt with the heat. This year, I tried again and put a new belt on. Knocking was gone. Freon was low and I unscrewed high side valve and it flew off. Realized I had a leak at the high side valve. I then changed the valve, orifice, and accumulator. Evacuated system with pump. System helda vacuum. Refilled freon (only one can put it in the green which according to autozone is way less than what the system should hold). Blew cold at idle. As soon as I drove off, it stopped blowing cold, only slightly cool. Clutch stays on as it should. The old orifice looked like it had metal dust on it. Could it be sensor or compressor? I have the dual manual climate controls inside. Also, my truck seems to be getting low on coolant lately. Not sure if that could be related. I don't have check engine light. Please help

Air not coming out of vents

I have a 1999 Silverado 1500 .When you turn on the blower for the AC or the heater you can hear the blower running but no air comes out of the vents. Is there a relay or sensor that could be bad? Air does come out of the top vents when defrost is on. Air comes out of bottom vent also. 10 amp fuse for ac/heater is good.

Ripped Off by a Dealership??????

A friend took his 1996 Chevy 2500 to a dealership to have the front drivers side axle seal replaced In doing so the dealership managed to ruin axle and the adjusting nut for ring gear. He said that he used a slide hammer which i dont believe, then he cut the mounting plate off the axle, and then Mutilated the nut with a punch and hammer. Which cost him and extra 600 dollars. I think He ruined the nut with the torch. then he tried to explain that he put a puller on the axle which makes absolutely no scents what are you going to pull off of? he said that the plate was cracked I can guess how that happened, Any thoughts? Thanks

2001 Silverado 4.8 V8, High Pitch Air Release from AC?

I'm getting a high pitch air pressure release noise like an , "Air Brake" from someplace in the front of the engine. It happens when the AC is engaged, defrost also. It doesn't do it when AC is off. Noise happens in an instant at rev RPM in park or during acceleration on the road. The AC pressures are all on specs and there have never been any problems with the compressor or system parts in the past. The compressor clutch cycles as it should. All lines are cold and hot as they should be to the touch during cycle. This started midway through last summer. The AC blows cold 40 degree air on the hottest most humid days. This noise is loud enough it turns heads when I'm passing people on the street. Hope somebody can help me out soon. :? :x :roll:

2012 Canyon 3700 Vortec

What would cause less fuel mileage? I have a 2012 Canyon with the 3700 Vortec engine. I have noticed that I used to get very good mileage and now it seems that it has gone way down. No engine light has come on, the smell of gas comes in the cab when first started. I have sent it to the dealer and they say that there is nothing wrong with the mileage but I know different. They think the mileage is normal. They can't read with the computer because no light has come on. I used to be able to go up to the cottage and about a quarter of the way back on a tank. The cottage is about 515km (roughly 300m) and the tank is about 66L (roughly 20gal), so about 640kms (roughly 375m) I used to get. Now I only get about about 380kms (roughly 220m) on a tank. Does anyone know what could be causing this? Also what should my rpm's be at when running on the highway anywhere from 100 - 120kms (60 - 80ms)?

94 chevy k1500 running issues

got a mechanical question for you, got a 94 chevy k1500 with a 5.7 v8 with throttle body injection, boggs down at stops and when accelerating basically anytime there is a load on the engine, fine when in park or neutral, replaced spark plugs, wires, coil, air and fuel filter, oil change, and idle air control valve. still does it not as bad but still does it, there is no cat to get clogged but the muffler does have a hole in it
