9-26-10 Where is a tcc solenoid in a 2000 Pontiac Grand Prix. |
9-27-10 It is in the side cover of the transmission along with the other solenoids. |
12-4-10 I have changed my brake pads and rotors on the front and pads on the back but my service traction system light still comes on. What else can I do. What else is there to do to service the system? I have a 2002 Montana Pontiac. |
The pads and rotors have nothing to do with the traction control system. You most likely have a problem in the ABS. A possible bad wheel speed sensor. You need to have the ABS computer scanned for codes. |
3-28-10 Grinding noises when I press down on brakes and when I turn wheel hard left or right service traction system message comes on. |
Get your front brakes and wheel bearings checked. |
4-26-11 I have a 2002 Buick Rendezvous and I have a Service Traction system light that comes on after a few minutes it goes off but my abs light and trac off light stays on.. What would cause this and is it expensive to fix. |
5-1-11 my front wheel wobbles for a short time, but then rides ok. Is this caused by the abs sensor. |
Could be one of many problems in the ABS system that causes this. Need to have codes scanned first. |
Sounds like a bad tire. Have them checked or rotated to see if that makes a change. |
5-27-11 My ml 320 traction light come on when i move say 20mph. |
5-28-11 My abs traction off service engine light pops up all at the same time. The other day I tried to start my car and it wouldn't start at all. Ended up push starting it, took to a mechanic and transmission, fuel pump, ECT all ok. He said he couldn't find anything wrong. Please help explain why my car is doing both of those! |
5-28-11 I drive a 2005 Pontiac grand prix GT and while I'm driving reduce engine power pops on my screen and when this happens once I brake at a light my gas pedal stops responding in R N D 3 2 1 but responds in Park then my screens shows service traction control. Then the car starts to roughly idle then shut off and it takes me a while to get moving again. PLEASE help! |
The throttle body on your Grand Prix is electronically controlled and when it goes bad, the reduced engine power light will come on and the vehicle will run rough, be hard starting, etc. Also, you have what is called an accelerator pedal position sensor that is part of the accelerator pedal assembly. These will give the same symptoms when it goes bad, too. Since it did set the light on, you will have trouble codes stored in your car's computer. This will help diagnose whether you need a new throttle body assembly or a new accelerator pedal. It would most likely need to be checked by a technician. |
6-21-11 Monte Carlo, once I turn left or right at times, makes a grudging noise and Service Traction System light appears, only does this once turning left or right slowly, almost 80% of the time departing from a parking space as well as parking. |
6-27-11 You probably have a bad hub bearing on your Monte Carlo. These have the wheel speed sensors built in to them, and when there is a problem the trac light will come on and usually the abs light as well. You can get the car checked for codes to see which side is causing you problems. Also check wiring harness to sensor for water intrusion and corrosion. |
7-19-11 2001 cavalier @ road speed engine will lug then Lunge then Trac lite comes on and stays on,Code says TCC stuck ON,Also @ stop engine lugs a little then is ok. But Monitor says PCM turned Traction control off. Any Ideas where to look? |
8-29-11 have a 2004 Monte carlo the ABS and Traction control light came on after doing a donut in a field on night. I have at the wheel off and checked the connections. Could there be a thrown bearing. If so how do i check to see if that is the problem. |
9-17-11 I have a 2007 chevy Cobalt SS the 4 door model the traction control light comes on all the time when I stay at a constant speed of 60-65 how do I fix it |
Did you check wiring to all four wheels? You need to get the computer scanned to find out what the code is. You are just guessing it is a speed sensor problem. Could be something else. |
You need to get the computer scanned to find out what problem your car has in then ABS system. |
10-5-11 I have a 1998 Ford E-150 Econoline van... I've installed the following rear drum brakes , wheel solenoids on the driver and passenger side as well as rear brake lines. Also I installed a new brake line from the front main box where all brake lines run from " I'm not sure what it's called but it's right under the brake line pump / fill reservoir.... Before during and after installing all this... I've test drove it on all aspect I'm getting the same results, out a 2 block street approx 18 times when I touch or hit the brake pedal I hear a winning sound kind of like you had. Manual car & put it in gear with accelerating at the same time, not a grinding sound!!! That lasts like 2 seconds its as if the brake pedal is rising or building pressure... Then immediately following that a knocking / pulsating sound is felt in the brake pedal slightly heard... It goes through approx 8-12 knocking. Then at the very end it seems as it's relieved pressure or something. Kind of like when your bleeding the brakes feeling !!! Does anyone have ideas or recommendations?I'd greatly appreciate your time and direction. Thank you - William |
10-13-11 i have a 2003 Monte carlo have had new brake pads and rotors now my abs and traction system lights coming on what could the problem be now. |
If the ABS light was not on before the brake repairs, it is possible that the person that did the repairs has damaged one of the wheel speed sensor harnesses. |
11-10-11 I have a 2006 Pontiac Grand Prix GT and I recently had the battery changed. Now it is telling me to service traction control, service ABS, and service effortless steering. I'm thinking the problem is something to do with the fuse box... Considering the fuse box had to be moved change the battery. Any suggestions? |
They may have caused a poor connection under the fuse box by moving it. This battery is tough to replace. Check the fuses first. |
12-21-11 I have a 2000 Pontiac Sunfire. The Service light, ABS, and Trac off light came on after a while of driving. I didn't notice anything different while driving or any funny noises. Whats wrong? |
Sounds like an ABS brakes problem. You need to get the computer scanned for any stored codes first. |
2-17-12 I have a Pontiac Aztec. The service traction system light is on. When I press the brake pedal, sometimes it feels like it's grinding or shaking, and it sort of tries to push upward under my foot. However, I don't have any trouble stopping, and the brakes and rotors have just been replaced (replaced after the problem started). |
You have a front wheel bearing / speed sensor or wiring to one of those sensors bad. Pads and rotors have nothing to do with ABS or traction. |
2-20-12 My 2006 Pontiac Grand Prix, my diagnostic codes are P1125, P2125, P2138...do all 3 codes mean I only need a APP sensor? |
Yes all these codes do point to the accelerator pedal. It is becoming quite a common item fail. But one other thing to check is a connector that I have seen problems with. Open the drivers door and on the side of the dash you will see a panel. Remove that and look for a flat electrical connector. Disconnect that and look for any signs of water. It may be actually went or the terminals might be green with corrosion. Especially check this if you have a sunroof since we have seen those leak down into that part of the dash and corrode the connector. If it looks okay then just replace the gas pedal. |
3-13-12 1998 Buick Regal GS symptoms are: bought yesterday - slight creaking noise when turning at low speed like in parking lots at stop signs etc - fine driving this morning - coming home today got progressively worse - felt as though there was less power during initial seconds of accelerate from stop and some chatter in/out of 1st - took some side roads on errands and the abs light, trac off light and service engine soon light all came on - removed abs fuses and felt as thought it was doing the same thing? Put back in and only the low trac light comes on (at most points of accelerate or when hitting bumps) and still very rough on low speed turning in both D and R - thinking it is probably a wheel speed sensor but I may just replace the entire hub assembly because the bearing, hub, sensor, and reluctor ring all comes in 1 package...whats weird is previous owner replaced the front hubs in 2010...? |
3-20-12 Went to the car wash, afterward service traction control system, service ABS system came on. What is the problem? |
3-24-12 I have a 2006 Chevrolet Cobalt SS 4-Door Sedan, and occasionally (but not all the time) my ABS light comes on and I have to restart the car to get it to go away and then it may or may not work. Further, my traction control light will come on at slow speeds or in combination with the ABS failure. I read earlier comments and I think it may be a bad wheel speed sensor. What do you think? Thanks |
There was probably some water intrusion into one or more of the wiring harnesses for the wheel speed sensors. If this is the case, it can cause corrosion which will require harness replacement. I'd recommend scanning the car for codes to see which wheel or wheels is acting up. |
3-26-12 I got a brake line replaced and repaired a year ago. It was leaking brake fluid. It happen again last Friday,why? This is on a 1995 Ford Contour. |
If the new line / hose replaced last year was not just rubbing on something, then it could be just a cheap part or contaminated fluid- if you are talking about a rubber line that is leaking. |
