Idle too high - Page 2

aamt07 · 09-09-2011, 08:05 AM

It looked like a pain I still haven't attempted to do it because I think my extra is bad also when I unplug the bad one on the car and plug the other one in it has no effect. I thought it would at least bogg it down. All the codes I'm showing are 41 42 & 51. I might have more in another test. lol this car is full of good codes it could be a lot worse.

Are you plugging this other TPS in while it's on a throttle body and properly adjusted? Or is this other TPS removed when you plug it in?

Removed. Properly adjusted? How do you adjust it or does the ecu do that for you?

You adjust it by checking the resistance between the terminals on the TPS, and rotating it on the 2 mounting screws until the value read is within spec.

Here's the link to the TSRM page on how to adjust it:
