2018 Challenger R/T Plus - Billet Clearcoat
YouTube it. Someone has probably had that come up.
The link below provides some good detail on the condition:Got a check engine light for my 2014 Dodge Challenger srt8. Has 16k miles on it. Code is p2097, which I looked up and says Code P2097 stands for post catalyst fuel trim system too rich bank 1, indicates the downstream bank 1 O2 sensor is registering a rich condition.
Any advice on how to check what might be causing this? I have noticed my gas running out faster. I would like to try to fix it myself before taking it somewhere and paying a hefty price for labor. I have reset the light and it came back on within an hour.
The engine controller constantly checks the #1 O2 sensor is functioning correctly. This can be indirectly observed if one monitors the #1 O2 sensor voltage levels. They go up and down at idle about every second (more frequently as engine speed goes up) as the engine controller changes the air fuel mixture -- ever so slightly -- and looks for a corresponding change in the voltage level from the #1 O2 sensor.Probably either that O2 sensor, OR the upstream one. If the upstream one is failing, it will well then engine to run rich/lean incorrectly, and the down stream one is picking it up.
OR stuck fuel injector allowing too much fuel. Since it is 1 side only, and too rich, probably not a leak anywhere in anything.
