HELP!! Accelerator pedal sensor issues

[ammojeep]

Hello all,

I am new to the site but was told this is a good place for off the wall issues.

I bought a 02 F350 Lariat LE with the 7.3l. After spending over $3k trying to resolve this issue, I have not succeeded.

After the engine is warm and things are running smooth, the pedal goes dead. Generally after I have got on it a little to climb a hill or pass someone. Everything else still works/ stays running. The check engine light only comes on after the pedal is depressed and goes out after it is released. I have taken it to the local dealer and they say it I'd the accelerator pedal sensor. Which I have replace and no success. After it sets for about an your or so (after everything cools down) the pedal starts working again.

I bought the legendary 7.3l for its reliability, and so far I love it. But I am using the truck go pull my horse trailer and cannot afford to have it cut out on me with livestock in the trailer.

Any input is welcome. Thank you all for your assistance.

Dave

It might be a longshot, but it is Free and a common issue anyway, so I think you might want to look into the problem of a shorted OD sw wire in the column. The link below assumes you're blowing a fuse because the the short is so established. But, when just starting to make contact with ground it can be just confusing the TPS (and some of these TPS's were so prone to failure there was a class action over them).

Look at this and consider taking a look at your wires. You don't have to replace anything, just reinsulate.

i agree with the overdrive cancel switch wiring may be causing your issue , and even if its not its worth checking to rule it out

OK thanks. I will check it out.

The only thing I am still concerned about is the temp issue. After cooling down, it starts working again. Just sayin.

But I will check it out.

So when ford replaced the pedal sensor did they replace the entire pedal assembly? The reason I ask is because there is a sensor on the pedal itself that can't be replaced without the entire go pedal being replaced. I just had to put a new one on my truck.

I had to replace the entire pedal. Some older trucks do have the removable sensor. The dealer wanted $800, I got it from O'Reilys for $160.

I will look at this as soon as I can. Thanks for the info. Might not be a bad idea for everyone to check this one out!!

Does anyone know where I can buy the wiring plugs that connect to the pedal and to the plug on the driver wheel well? I think i might have tracked a possible issue. Someone had cut and replaced a wire from the pedal to where it connects to the plug on the wheel well. And a couple of the other wires look a little less than desirable.

Thanks

Electrical connectors
Maybe you can find the connector in there?

I see that this catalog is for 08-09. Do you know if there is one for 02?
