Engine/Transmission (1998.5 - 2002) po122 code but no noticeable issue

[drlabatomy]

After rebuild of my free spinning hub kit from EMS offroad my mechanic got a check engine light that came on. Multiple scan and resets of the light keeps coming back with a p0122 code that he can't reset. He thinks its either one of the computers or TPS?? Anyone have any issues with this code i might need to know about. All voltages outgoing are correct. When accelerated while sitting and while driving everything seems normal. There is no lag or anything but the code still wont reset.



He looked around on the internet and checked with local dodge mechanic fairly familiar with cummins diesels to no avail. I told him i'd check here because you guys are the forfront for any info dealing with dodge diesels.



Thanks for the help

Have you tried resetting the APPS?


Resetting the APPS, turn on the key and with it left on, disconnect the batt negatives for about half an hour or so to fully discharge all the capacitors in the PCM. After the elapsed time, turn off the key, hook your batteries back up then turn on the key without moving the pedal. Now slowly depress the pedal all the way to the floor and then release it slowly all the way back up. The PCM re-learns the voltage curve and your code goes away...

It's work for others on the code P0122

Thanks for the help we tried that and 20 miles later the check engine light was back on.



I have found another hopeful solution i am installing it this week.

Replacement TPS/ APPS

just as a followup i did have my mechanic install the apps and it solved everything. All codes are gone and truck runs better than new. Now im in the process of getting rid of the rust...



Thanks for the help.
