Truck will go back to idle while accelerating or if I just push the peddle past 1/4 throttle. Replaced apps with a timbo and its still doing it. Did the key cycle for codes and it gave me a list...pcm side 0622. 0122. 1765. 1693. The ecm side...0122. 1693. 1689. Looked up all the codes and was hoping there is a single problem possibly a wire causing all of this. Really getting on my nerves. Any ideas?

 

The codes are pointing to possibly a bad or corroded ground, bad wire, misplaced or misaligned connection, a connector not fully pushed in and locked in place.

0122 throttle position sensor too low
0622 generator/alternator field too high
1765 trans 12v control relay control circuit
1693 code cleared in JTEC module( general fault code)
1689 no communication between ECM & pump injection control module.

You need to reset your APPS, check your alternator, your transmission relays , and check the wiring to the ECM and Fuel Pump for corrosion. You might have a bad or corroded ground on the truck or battery.

 

Kinda what I was leaning towards had terrible luck with batteries not grounding and getting corroded to often resetting the apps right now gonna clean battery terminals and then idk where to go from there guess check the alternator connections
