  1. PO135 – O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

    This has nothing to do with your fuel, so no worries there. New plugs and wires won’t hurt but not needed.

    The Heated part of the oxygen sensor is failing to do its job and causes the code PO135 to be stored. Replacing the Upstream Oxygen Sensor will fix the problem. (the upstream O2sensor is the one located before the catalytic converter)
