Well I’m running the quadzilla adr and I in plugged the quadzilla map sensor harness & I plugged the regular one back up and it runs out of limp mode and runs good but as soon as I plug the harness back up it goes back into limp mode I’m getting 3.7 volts at the map sensor stock harness

Okay, so I decided to replace the terminals on my 2001 dodge Cummins so I replaced all 4 battery terminals and when I went to start it up it started right up but then my check engine light illuminated and when I went to drive it it was in limp mode and it ran like ****. I did the key trick and 1488 and 0237 code came up so I replaced my map sensor and the problem is still occurring.
