You can unplug the pcm connector, turn the key on and it still shows oil pressure on the instrument cluster. #4 terminal on pcm has 5 volts on it with the key on and pcm connector unplugged.
I have already changed out the PCM, replaced oil pressure sensor, wiring checked out good.
This problem happened Immediately after I pulled the engine from a 2017 ram 1500 (5.7) and replaced it with a 2016 ram 1500 5.7.
So my CEL will stay on now, when the engine is on or off the pressure will remain the same. (Always showing over 92psi)
Any help or recommendations are appreciated.
