I have the trouble code titled Bank 1 Sensor 2 O2 Sensor Heater Circuit Malfunction. Can someone tell me what this means, where this O2 sensor is in my car, and what has to be done? It doesn’t sound like the trouble is in the sensor itself, but some wiring circuit in the car?
Bank 1 is on the same side as cylinder one on an engine.
Sensor 2 is the O2 sensor after the catalytic converter on bank 1.
