Code P2096 Acura Description

The P2096 diagnostic trouble code for Acura vehicles indicates that the Post Catalyst Fuel Trim System on Bank 1 is running too lean. This means that there is an imbalance in the air-fuel mixture after it passes through the catalytic converter. The fuel trim system is responsible for adjusting the air-fuel ratio to maintain optimal combustion in the engine. When the system detects that there is too much air and not enough fuel in the mixture, it triggers the P2096 code.
