I did a search, but nobody seemed to have this same exact issue. Was stopped at a light yesterday, went to accelerate, and nothing. Truck idles fine, starts fine, just won't accelerate. Could it really be something as simple as the accelerator pedal!?!?

 

That is where I would start!! Good Luck!!

 

You can get a replacement throttle position switch from the parts store. I'm not sure of the number but I do know that Dorman makes it.


Found it:

If the link doesn't work the part # is 699-200 Accelerator Pedal Position Sensor

Dorman Products - 699-200

 

There's a recall on some truck's for this. Call your dealer

 

I JUST OREDERED ONE FROM ED FOR 87$ SHIPPED

sorry for the caps

 

well, it turns out it was the #45 fuse.....10 amp. Replaced it, all is well--for now. Will let you know how long that lasts!

 

The IVS (Idle Validation Switch) contacts are normally open. They should close when you press the skinny peddle to send a signal to the PCM that you are off idle. Without that signal the PCM will ignore the throttle position signals. Dirty contacts of the IVS will give the symptoms you have described. You can try some contact cleaner spray to see if that helps before buying a new TPS.

 

I know exactly what your problem is! I had this happen last year, it will keep blowing that fuse - guaranteed - it will usually happen during turn. The issue is a wire that is rubbing within the steering column due to a bad wiper control/cruise control paddle on the steering column. You need to replace the controller on the right side of the column. Take the column apart and you can remove it pretty easy. I seem to remember that the controller was about $40.

I was completely dumbfounded, but do a search, and you'll find the info here.

 

thanks Dirtfarmer, this is what I suspected also, as it did occur during a turn to the right. Guess I'll have to get into it sooner or later.

 

I had the same issues minus the blown fuse...I just repaced the whole pedal assembly. If your SES light came on you need to get the code cleared, just some food for thought.

 

I have bine on here before,i have put 3 replacement pedals in my 2002 F250 PST.My truck worked fine the last couple times i drove it until i got rained on,twice.We also had a storm and i went outside to check to see if it worked and the throttle didn't work after the storm.It was fine the night before.Any ideas?

 

I would check to see if you have a leaky windshield.

 

I have checked to see if there is any dampness on the inside of the firewall and floor each time and they are dry.I'm getting frustrated.
