I have replaced both sensors and code will not reset. Don't tell me about the drive patterns to reset the readiness codes, done all that too. gas cap is good also....only thing i haven't been able to do is check the A/F heater fuse or A/F heater relay as there isn't one in the fuse boxes. besides the readiness status for the A/F heater is ok... the readiness for the catalyst monitor, evaporator monitor and oxygen monitor are incomplete even after every driving cycle known to man... Please someone help me with turning this code off.....

Those 3 pending codes take 100 miles or so for a pass/fail decision.

Believe need to resolve the p1135 before monitors will set.

Check bbbind.com for electrical schematic of heater sensor circuit.
If voltage to heater and circuit to ECM good then either sensor heater element not correct or ECM problem.

Measure ohms of old sensor( if not open) compare to that of new sensor.
OEM replacement?
