p2097 in a 2006 subaru forester?

Question

p2097 DTC code. What would cause the rich fuel trim condition and is the sensor wrong?

Answer 1

Are you using 91 octane fuel? if not I would erase the code and fill up 91 octane from Shell and see if that fixes the problem. If its does not  and there are no exhaust leaks, I would replace the oxygen sensor on bank 1
