Engine/Transmission (1998.5 - 2002) 2000 and p0121

[jtisdale]

2000 ETC 5 speed 118k stock except edge ez. Every once in a while it seems to loose power (possible dead pedal?) and throws the CEL the p0121 code. I breifely looked it over, cleaned and dielectric greased the EZ connections, recalibrated the apps, checked the fuel pressure (excellent), found a bad IAT sensor (that still needs to be replaced). I am leaning toward the possibility the apps is on its way out, especially since it happened again after we recalibrated the apps.

Any ideas?

Thanks Jim.

How do you "clean it up and adjust the voltage"? I am getting the same code. It randomly drops to idle and I have to coast to the side. $439. 99 for tps at AutoZone. Where do I find the specs on it. It looks easy to get out, but hate to take it apart without knowing the procedure.

The tps at AutoZone may be the 12v unit. If you do some searching, the dealer may be the only source for the APPS. SNOKING

These part numbers (minus the letter suffixes) are from the model year 2000 Parts Catalog. Even though the part descriptions only mention 1998-1999 these are likely (check before ordering!) used for all the 24-valve Rams.
