I tried to send this question yesterday but may not have been logged on properly.
2004 Grand Cherokee, 4.0l...184,000 miles
Error Code : P0141 Oxygen Sensor
Heater Circuit Bank 1, Sensor 2
I have: A.. replaced the Sensor, assuming the placement of bank one is the closet to the front off the car, sensor 2 being the after catalyst sensor.
B..inspect all the wiring back to the ECM, cleaned all the connections including the one on the ECM with Electronics cleaner and reseated them.
C.. Cleared the engine code light with My Actron code reader
D..Cleared the code by disconnecting the battery
E.. Stamped my feet and thrown my Car manual in frustration!
Any suggestions as where to look or go next?
