Can't seem to find what I'm looking for by searching so...I have a 2001 Camry 6 cylinder w/ auto. I have the check engine lamp on and the indications from the OBD-II reader is that two of the three 02 sensors are gone. The code given is both P1155 and P1135. This appears to be: Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1) and (Bank 1 Sensor 2). Does this mean that both 02 sensors on the manifolds (not the one near the Cat) need to be replaced?
Thanks for the help.
After much BS from the dealer...they wanted over $100 to hook up a OBD-II tester.. I dove into the failure myself. What I found was that there was no voltage on any of the three heater circuits on any of the A/F sensors. All it was was a loose connector at the rear of the fuse block. Put it back on, it cleared all the failure codes and all is well. Now a letter goes out to the greedy dealer! :whatwhat:
