Codes p2115, p2116, p2166 and p2167

This sounds like it could be the TIPM. to be sure lets do a CAN scan which is the future of automotive repair. you can get a CAN scanner from Amazon for about $50.00 .here is a video to show you how:

Here is a guide to help you check the engine wiring with the diagrams below. I have also included the TIPM replacement instructions as well just in case It is easy to install because it self initializes. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Thank you for the reply. I have a history with the vehicle, I put 12,000 miles on it, but I knew it had an intermittent throttle position fault and every now and then it'd go into limp mode p0700 along with TPS fault. I bought a launch x431v+ and attempted a relearn which set hard faults, I purchased a new bellcrank accelerator and new reman throttle body and still had hard faults and couldn't do the relearn with the launch. Everything checked out, I thought possibly maybe I need a relearn with a capable scan tool. I took it to Gary Wilkins Gary's Car Craft in Orange Park Florida for a diagnosis as he has dealt with this before on these 3rd gen Ram pickups and he said he had 100 percent success rate with this accel pedal position fault and all it was was a relearn, he has the autel ultra the US version and that machine was able to handle the relearn and I can feel the difference of the new bellcrank accelerator. I'm used to being able to manipulate these 3rd gens without a scanner, doing battery disconnect type relearns and I guess I was so into the diag that I thought possible bad signal or return on app 2 but I since found out on early Chrysler you can't trust scan data on app 2 voltage drop because it's a b.s. parameter. I'm lucky I was able to take it over to Gary's and he's straight up he just charged me the diag hour that's it (he took of me). Thank you for your response and I really appreciate the wiring diagram, me working that diagram is what made me come to the conclusion that I probably needed to try a relearn with a better scan tool(no knock on the launch, my Dodge is a 2003 but so far the launch has been great honestly). Thanks for helping me.
