I have a check engine light on. I checked the code and was told it was the o2 bank 2 sensor 1. It has 4 o2 sensors. Two before and two after the cat. Converter. Can you tell me which o2 sensor this is?

Thanks!

Driver's side before the catalytic converter. Before you replace it, you might want to also make sure the wires are not chaffed / shorted or the connector accidnetally disconnected. It happens and would be a free fix rather than a 75.00 sensor.

Let me know what you find.
