I switched grills, to an all blacked out grill. When I put it on, and re started the jku, it threw a P0072. I think I may have hit a wire when putting the grill on. It is the only thing I can think of that was done that day besides a normal oil change and reset of the oil change light. Any one have a clue where to check for the P0072 error? I know what the error code is, just not where to look to see about getting it fixed. Also, will my AEV procal clear the code once I get it fixed?

The ambient air temperature sensor is located at the lower left corner of the grill, (driver's side).

Look for broken/disconnected wires to it.

Is it in the loom, or a seperate set of wires? Got a pics to go by? Since the code is low voltage, think that means it is still connected, maybe just nick'ed?

Okay, easy enough. Found sensor, wire looked pinched, freed it no problems. error code now gone. Check engine light flashes 10 time then stays lit. Can I Clear this with my procal or is it a trip to the dealship? Damn if so.

After three good trips, the light should go out. (Unless, or course, it's on for another reason.)

A pinched wire that threw code may be broken inside the insulation. The code could come back at any time.
