Check Engine P0037
Has anyone had experience with the check engine light for code P0037? If so, what needed to be done to fix? Also, where is Bank 1 Sensor 2?

I used lower cost replacement parts first, Wrong !!! does not work. Changed to Denso brand sensor, it worked perfectly. no more CEL code.
DENSO 234-4509 O2 Oxygen Sensor direct replacement from Amazon, it worked for me. Cost $71

Bank one is located at the back of the engine as shown in the diagram above. I've not needed to change bank 1 sensor 2, but have seen it. Remove your plastic engine belly covers under the car. Locate the exhaust coming down from bank 1. Sensor 2 is there as the 2nd sensor in the system and just before the point where both banks come together under the car and converge into the main exhaust pipe leading under and out the back. IIRC this sensor has a long wired electrical connection so trace that back to its plug in point to ensure you can get that off before removing sensor.
