1488 & 0237 engine code

[Molina]

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.

The MAP sensor code was tossed because the 5V signal voltage is too low so that push the sensor out of range on the low side trip the P0237 code. It might be wiring... But you might end up sending the ECM in for repair.

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

That being said it time to call @Quadzilla Power and have them test and diagnose your Quadzilla is it a wiring issue or a module issue.
