Hi -
After dumping the code (PO136), I replaced the bank 1 position 2 O2 sensor (per the code - also thanks to those with tips on how to get the center console out). Unfortunately this did not fix the error. On my monitoring SW the sensor shows a zero voltage outout. In order to eliminate the catalytic converter, I plugged the suspect sensor into the wiring harness for the other post catalytic converter sensor. After heating up, no issue with registering voltage. This should have exonerated both the new sensor and the bank one catalytic converter.
So I completed a continuity check from the sensor connector to the input of the PCM which showed no broken wires, etc. This seemingly points to the PCM unless I am missing something??
Any way to eliminate the PCM?
Thanks
