Code P2097 2008 Ford Fusion Description

The P2097 diagnostic trouble code (DTC) for a 2008 Ford Fusion indicates that the post-catalyst fuel trim system on bank 1 is too rich. This means that the engine control module (ECM) has detected that the air-fuel mixture after the catalytic converter is too rich, meaning there is an excess of fuel in relation to the amount of air being supplied to the engine. This can lead to decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
