Archived TPS problem 03 cummins

[JTSDIESEL]

The problem is, the truck does fine until full trottle (or pedal is on the floor). Then it just surges for a sec, and goes back to an idle. I put on a new tps, checked voltage and ohms on wires, and had computer checked and reflashed. Still the same thing is happening. The check engine light stays on even if the codes are cleared. The codes are P02123 and P02127. any help would be appreciated. Got to have this truck back on the road ASAP!

2123= Pedal postion sensor 1 high.

2127= Pedal validation switch 2 low.



The TPS on the 2nd generations were adustable for current out put, I don't know if the 3rd generations Pedal Postion sensor is.

As I recall, there are adjustments to make with automatic transmissions. No adjustment necessary on manuals.



Sorry I can't be of more help, but maybe someone will chime in that knows more.

Thanks but I already knew what the codes were, and that there was no adjustments on the TPS. Just didnt know if someone else had the same problem, or knew how to fix it. I really need my truck back on the road. Thanks again

If you go to "The Premiere website for Hemi Ram and Hemi SUVs. " and scroll down the left side you will find a free download for a factory service manual. There is a section for step by step to test and trouble shoot for the codes. You might also check out 2003 TSB's There is a tsb for 03 autos for water in one of the conectors
