Anyone know the part number for the APPS, accelerator pedal position sensor? Mine is under the battery tray driver side.

Mopar or NAPA number would be great

2003 diesel 6spd 4wd.

Parts store seems confused.

Thanks!

 

There's a good aftermarket tps for the engine mounted apps. I got mine from tst products - $169. I don't know if there is one for the batt box mounted apps. I've heard they are different but I don't know why. Try Mark @ tst. Craig

 

Continue to have problems with code P2121.

I decided to clean all grounds again on truck.

Found the big cable on driver side lower block with some corrosion.

All seems well now , code has not come back.

 

2 weeks of driving and no more codes, can't believe it was a ground cable.

Glad I never blew $500 on a TPS.

Hope it lasts!

 

Boy, I sure can! I had a heck of a time with grounding points on some aftermarket stuff. No dirt or corrosion at all, just had to find the best places to land the ground wires. I had long cranking and gremlins in the hvac and lift pump. I hope it keeps working for both of us! Craig
