Mcs p2196 p2ac4
I've had the following two codes pop up twice in the last two weeks. No obvious change in performance or operation of the engine, everything 'seems fine'.
P2196 O2 Sensor Stuck Rich
P2AC4 Front O2 Check Signal
My immediate thought is the Front/top O2 sensor is going bad.
Any other theories or trouble shooting I should do?
