Re: Check engine help!
Bank 2 sensor 2 would be the same as 2/2 which is one of the downstream sensors. My guess is if the code is for the sensor heater circuit then the sensor needs to be replaced. That said, all the downstream sensors do is monitor the catalytic converter performance, they are not critical to engine operation like the upstream sensors.
