2003 excursion tps problem

Ok I have an 03 ford excursion with the 6.0 diesel. Truck runs and drives but have codes for TPS. At times there is no problem but sometime when you get into it the RPMs with jump up and down. Let out of it and will go back to normal. I have a few of the truck and have pulled the pedal out of them and tried them. No luck same codes come back. All data looks right but wondering if the pcm is giving me these problems and not the pedal.

It is more likely that the wiring between the PCM and the TPS is the problem.

Yeah I kind was thinking that. As soon as you clear the codes turn key of then back on they come back. Just need to find the right wiring diagram with a write up of what number I should be see and when
