hello all, scrolled through threads couldn't find my exact situation. so here it is 01 dodge 2500 4x4 auto trans. codes are 1757,1762,1693,this is doing the key cycling trick 3 times. those are the P PCU codes, then the P ECU codes are 0234,1693 i know what they mean. no loss of power,no dead pedal,no more smoke than normal,trans seems to have locckup issues at certain speeds nothing real bad though, stock setup except KN filter in stock housing, 4" exhaust straight back, then dumped.codes present before exhaust mod. did put 33x12.50 17 tires and wheels on it long ago,fuel filter is new, dont change anything fpr the better or worse. IAT sensor new looking in appearance no soot. will be checking this thread periodically today let me know questions if any thanks to all. new Factory LP 60,000 miles ago which was when i purchased truck with 60,000 miles on it. cracked lines open got great visual fuel pressure doesn't seem to starve for fuel but i think th CPU is trying to de-fuel it cause the code. only code shown when on a scanner is the 0234 always comes back sorry punctuation so terrible in a hurry thanks again "NEWBIE"

 

the map sensor might be the problem. if its reading wrong pressure, saying its to high, would cause it to throw the over boost code and defuel good luck with it. idk if ya can the map, but may be able to clean the map sensor. i know ya can the IAT sensor, so might try pulling it, and cleaning it up some.

 

also check the tps

 

thank you very much pulled it out just now going volt test it 2 see if its in range

well was ponderin that 160.00 aftermarket plug to see if it changed anything the one that goes on bottom of apps as opposed to the 500.00 factory replacement i steer clear of factory stuff they couldnt get a plastic mold figured out when they made this body style much less fuel air etc
