I used my KIWI OBDII to check for codes, and it showed P0698 APPS supply voltage too low. I cleared it, and it never came back. So now I'd like to know if the pedal itself gives a smooth readout when I depress it all the way.

 

I just talked to 2 mechanics (one car and one OTR truck mechanic) about that. They use expensive scanners ($3k+) and they can read everything a tps does. I replaced mine and it was the best $169 I could spend. It fixed problems that I never would have expected. Craig

 

What is it doing that causes you to think APPS? Just curious cause my truck drops rpm when you are coming to a stop, it will go down to 600 rpm then come back up to 700 750 rpm where it normally idles when i push the clutch in while moving it does it but won't do it if i'm setting still, reving on it in neutral.
