Question

What does obd2 code P 2097 and P0297 mean? And what repairs are necessary?

Answer 1

P2097 Downstream fuel system rich Bank 1 Sensor 2

Inspection would be the first assessment If you have a exhaust leak at the front 02 sensor this would cause the ECM to go rich due to a false reading of the front 02 sensor which would cause the rear to be too rich for the catalytic convertor to handle.,
