Code P2096 2008 Ford Fusion Description

The P2096 diagnostic trouble code (DTC) for a 2008 Ford Fusion indicates that the post-catalyst fuel trim system on bank 1 is too lean. This means that there is an imbalance in the air-fuel mixture after the catalytic converter on the side of the engine with cylinder 1. The fuel trim system is responsible for adjusting the amount of fuel injected into the engine to maintain the optimal air-fuel ratio for combustion. When the system detects that the fuel mixture is too lean, it means there is too much air and not enough fuel in the combustion chamber.
