Starting to troubleshoot this code.

P1122 - Throttle Position Higher Than Expected

Car drives fine. Idles 1500 when warm.

I've read that people end up changing the TPS on this one.

OBD Software shows 42% TPS open at idle!

update:

Removed original TPS screws and attempted to adjust. Adjustment to the end would still show 31% open.

You don't have to drill the screws, a good pair of wire cutters will work, you can grab and turn the screw:



10/1 update :

Purchased cheap knock off TPS on ebay for $25. Will see if that fixes it and how long it will last. I've heard that the cheap ones go out quickly.

Got the new TPS. Took FOREVER. I suggest getting something that costs a little more and will arrive earlier.

OBD2 now shows 8%-88% throttle through the range. Will have to calibrate with volt meter. Check engine light is now off. High idle has also been fixed.

Car runs amazing now. The car must have been in limp mode with no timing advance. Now part throttle pulls nice and smooth all the way to WOT. Such a simple fix to such a big problem!
