resetting codes new speed sensor 98 mustang 3.8L 6 cylinder

[dawood]

A diagnostic scanner reported a bad speed sensor, so i replaced it with a new one. There was no improvement, and i was told the old codes needed to be deleted and allowed to reset. How is this done? No one seems to know and i havent been able to find any videos on youtube for it.

with the introduction of OBD2, it will usually take a scanner to clear the codes from memory.

What was the code you had before? What kind of improvement are you expecting to get? what is the problem with your car?

You start off describing the last part of your diag tree but I have no idea what you are trying to do.

What happened from the beginning? Did your "check engine" light come on or did you start having a driveability problem? Why did you scan for codes. What was the actual code numbers you pulled?

The more information I have the more informative answer I can give...

I had alternator replaced on 2006 Ford Focus wagon and mechanic said he had to drop the front axle. Is he pulling a fast one and where exactly is the alternator situated?

[carriedi]

have you looked at your engine to see where your alternator is located at? Does it look like there is room to get it out of the area where it is located at? Without looking at the alternator's location myself, there are some vehicles that you remove the axle to allow enough space to get the alternator out.

that being said, there is an engine roll restricter that can be unbolted. with the transmission in neutral, that will allow the engine to be pulled (rolled) forward and would allow the alternator to come out through the top.

I am going to change the spark plugs in my 1997 Sable. The engine is the Vulcan.

I bought 6 AGSF32FM plugs. I do not have a guage but the gaps on all of them visually look consistant side by side.

The gap required for the car is .044.

The Parts Guy at my Ford dealer tells me that the mechanics don't bother gapping the plugs, and just pop them in.

Other people have told me to do so.

I have two questions: does anyone know the gap of the plug virgin out of the box? Is it .044?

Secondly, do you gap your plugs or no more?

Clarity is appreciated.

Always check the gap.

you don't know if someone has dropped the box in transit. The problem comes when you have to adjust the gap. Fine wire platinum or iridium plugs have a very fine tip. so don't damage the tip when you gap the plug. Use the gap tool that moves the ground electrode

Found a gap tool. Out of the box gap was almost .060. Had to gap to .044.

If Ford is not gapping at the dealer, and putting them right in, we are all in trouble.

Simply unhook the ground cable off of The Ground Terminal on your battery for about 2 minutes and then the computer will be reset and codes will be cleared I have had to do this multiple times to get codes cleared after I have replaced parts( you will only have to do this one time each time you want to clear the old codes)

My1994 ford escort keep blowing the fuse for the fuel pump I have replaced fuel pump replace fuel filter and the fuel safety shutoff switch put a new gas tank can someone help me out with this ongoing problem

[carriedi]

what fuse keeps blowing? does it have anything written by the fuse or a fuse number? What fuse box? Inside the passenger compartment or in the engine compartment?

if it's the 30A fuel injector fuse, it powers up the pcm power relay and the fuel pump relay and goes to the alternator.

does it blow right away or does it take some time? If it blows right away, you have to look for a short to ground in the circuits. If it blows after you drive for a while you may have to separate the circuits and see if you can narrow down what circuit is the problem.

it's going to be tough to find if it takes a while to blow the fuse. You will need something that can measure the amp draw on the different circuits while the car is driven and see how much the draw is. Try looking at the wire harness for anywhere it might rub on the engine or the body and rub through. Wiggle the harness to see if you can make it blow the fuse.

a direct short would be easier to find. They make tools that send a tone through the circuit and you can follow the wiring until the signal stops and that's where you look for the short.
