I have a 14 ram 1500 tradesman. I have the 3.7 v6. I’m having trouble with the a code that comes up when I go into a passing gear on a cold start p0523. If I drive around til operating temp and go into a passing gear no CEL. Also when in a passing gear the coolant temp will sky rocket upto 135+ depending on how long I Stay with it pressed. As soon as I drop speed or no long press the gas pedal down far the temp drops to normal. I did recently replace the engine. I’ve taken it to a mechanic and they can’t seem to find the issue. They’ve checked all the electrical and all seems fine. Changed the wiring harness and still have the issue. Can someone shed some light? It has coolant and no light for anything other than the p0523. Thank you in advance!
