My wife told me that the check engine light came on today on the CX-5 (2013 2.0Gas, 80K Miles).
She did not notice drivability concern, except saying the engine 'might be' a bit louder at loads.
I used OBD scanner and retrieved two codes:
P0172 running rich, P013a downstream O2 slow switch.
Either one will trip the CEL, so they were on at the same time.
What puzzles me is that fuel trim is determined by upstream O2, which might cause P0172, but what are the odds have both sensor fail simultaneously?
From Google not many people have the experience of having both codes (at least people who were bothered to post online).
I am wondering anyone can share some thoughts here?
Thank you.
