Code P2096 GMC Description
The P2096 GMC code refers to the Post Catalyst Fuel Trim System Low Limit on Bank 1. This code indicates that the engine control module (ECM) has detected that the fuel trim for the post-catalytic converter oxygen sensor on bank 1 is outside of the specified range. The fuel trim is the adjustment made by the ECM to the air-fuel mixture to maintain proper combustion. When the fuel trim is too low, it means that the system is running too lean, which can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
