pedal position sensor?

I went offroading last night and ran great until this morning when I washed my engine(cover the intake with a bag) but... now my check engine code is saying pedal position sensor... where is it and how much is it?

I think this would be the TPS (Throttle Position Sensor) and it is attached to the throttle body. Anyone have a pic of this? Try to disconnect all the harnesses at the throttle body first and check for water in them. Maybe use a little WD40 to get out the water, then plug back in. Maybe there is just a short.

Here ya go, and throttle position sensors are pretty inexpensive to buy (Autozone, Kragen, etc. should have it) and easily replaced. Only two small (T-25?) torx screws hold it in place. Make sure to align the little slot in the new TPS with the tab that sticks out of the throttle body so it engages correctly. And keep the high pressure sprayer off the sensors.

When you have a choice, buy American.

I don't know how touchy Jeeps are with the non-OEM TPS sensors, but back when I had my Dakota, I posted on Dakota forums and some members did some tests and found that the signals of the TPS sensors from the auto parts stores were WAY off from the dealer parts. The signals were bad enough that on many vehicles the sensors weren't functioning correctly and the trucks still had issues. Might be a worthwhile investment to shell out a few extra bucks and buy one direct from the dealer. Speaking from personal experience, I have also learned that buying sensors from the dealer is a smarter choice...costs more, but you know they will work properly. The exception to this is if you know a company is the provider of the OEM part...then you can buy the part direct from that company (or a company who sells that brand). ie. NGK makes the O2 sensors for the you can spend a crapload at the dealer on O2 sensors, or just buy NGK O2 sensors from another place for half the price.

I work for the owner of a Chrysler dealership...I've found this site to be pretty close in price to my "employee pricing" aside from the shipping charges.
