I'm having an issue with the throttle on the vehicle listed above; the wiring to the Throttle body was changed and I'm not sure that the connections were spliced correctly. The problem I'm having is the Lightning bolt symbol is on the cluster, scanning the system shows TP sensor 2 has no signal change when depressing the throttle and the vehicle goes into limp mode. I have replaced the throttle body with a new part with the same result. I have looked at the diagram from the OEM service manual, it shows that the 3.7L engine does not have the style of Throttle body that is on this vehicle, it shows that this style was used on the 5.7L version. Could someone advise me as to the proper wiring schematic for the 6-pin connector at the throttle body, showing the circuit numbers. I have done a pin out test from the connector back to the ECM all wiring tests okay, but I'm not sure if the pins are in the correct position on the connector.
Thank you for your assistance.

Sure, here are the throttle body wiring diagrams and pin out for the 3.7-liter engine. If you need the complete engine wiring diagrams let me know and I can upload them for you. Check out the images (below). Please let us know what happens.

Thank you for the prompt reply, this helped a lot, unfortunately it didn't solve my dilemma. Still am getting erroneous trouble codes which lead me to believe that the issue is in the PCM as everything else checks out. I'll keep you posted on my progress.

Hi Ken,

Sorry it has been a while just been super busy at work. Still having issues wiring is connected as per the diagram you sent the codes that I am getting are as follows P060E, P062C, P2166 and P2167. When I watch the throttle position 1 and 2 using my Autel scan tool I can watch the TP sensor #1, using graphing, voltage move up and down with pedal movement however TP sensor #2 shows no sign of voltage change whatsoever. Any thoughts?

These are all throttle pedal position sensor codes which makes sense that the second TP sensor is not seeing any movement. I take it you fixed the wiring at the throttle body correct?

P060E - Internal Control Module Accelerator Pedal Position Performance
P062C - Internal Control Module Throttle Actuator Control Performance
P2166 - Throttle/Pedal Position Sensor "E" Maximum Stop Performance
P2167 - Throttle/Pedal Position Sensor "E" Minimum Stop Performance

If so I would replace the accelerator pedal which will have the new sensor in it. Here is how the job is done, clear the codes once completed. Check out the images (below). Let us know what you find.

Hi Ken, yes I did verify wiring at the throttle body, it is as your information showed, I have replaced the accelerator pedal/sensor, the P2166, P2167, and P062c have all cleared I still am getting P060E even though I did a hard reset. Watching the voltages on my scanner they move as expected based on pedal position, one thing I have noticed is APP2 voltage periodically drops to zero momentarily then recovers. Watching it on a graph you can see it as well as the voltage reading going to zero. Another thing I find strange is the throttle angle doesn't change it is constant a 63% regardless of pedal position and the valve does not move. I know that the ETC motor is capable of moving the throttle valve because if I apply power to pin #1 & ground pin #4 momentarily the valve moves, it is like the PCM is not sending the signal to the ETC. I am considering taking the PCM to the local dealership to have them flash the programing, What are your thoughts?

Yep, that was my next suggestion. It could be a bad PCM as well. Here is the location and how to change it out.
