I have a code PO135 and have changed the o2 sensor twice, still get the code. I just have the transmission
rebuilt and did not have the code when the 04 Explorer went in.
JA: OK. To minimize me, please click the down arrow at the top right corner of this box.
Customer: can you help
JA: Have you located all of the vehicle's oxygen sensors
? Are the wires leading to and from each intact and in good shape?
Customer: Yes, the code says it is on Bank 1 sensor 1.
JA: What is the model/year of your Ford?
Customer: Are you reading my responses, its a 04 Explorer
JA: No. I'm the Ford Mechanic's Assistant.
Customer: So, can you help?
JA: What year is your Ford?
JA: Are you hoping to fix this yourself? What have you tried so far?
JA: Anything else you think the mechanic should know?
