Probably a faulty sensor. Keep everyone posted...Hi everyone. I just purchased a Limited Renegade 2 nights ago and my check engine light just turned on. I'm taking it to the dealership in the morning. Did anyone else have this problem? I'm hoping it's nothing serious. I'm only at 115 miles
Allobyte, that was your cure for a bad Power Takeoff Unit.Yes is the control unit problem. Call the customer care, you have to update the software.
meanwhile if you have some problem unplug the negative of the battery for a while and all restart to work fine.
Good to hear - wonder where the leak was, since we don't have gas caps on the Renegade... maybe the capless seal mechanism was faulty? Did your service record show what part was replaced if any?It ended up being a leak in the vapor recovery system. They worded it slightly different, but still the same thing. Fingers crossed this is my only problem
I brought the Jeep back to the dealer yesterday. They read the codes, restarted vehicle, and a bunch of new codes came up. I guess this happened several times, codes would appear, clear, restart, new set of codes....I was driving in to work this am, my second day with the Trailhawk, when my 'check engine' notice came on.
That diagnostic makes sense. The ESIM acts a vent in the case of a large pressure differential. THe vent is mechanical with a switch to register it to the ECU. so either bum switch or bum mechanical bits would trigger as a leak.My paper work said : TEST AND FOUND ESIM VALVE. STUCK WON'T CLOSE THE SWITCH. REPLACED ESIM (EVAPORATIVE SYSTEM LEAK DECECTOR) CODE P0440 GENERAL EVAPORATIVE SYSTEM FAILURE
My car has been fine since then.
