Code P2097 Acura Description
The P2097 diagnostic trouble code (DTC) for Acura vehicles indicates that the post-catalyst fuel trim system on bank 1 is reading too rich. This means that there is an imbalance in the air-fuel mixture after it passes through the catalytic converter on the first bank of cylinders. The fuel trim system is responsible for adjusting the amount of fuel injected into the engine based on various factors such as engine load, temperature, and oxygen sensor readings. When the system detects that the fuel mixture is too rich, it means that there is an excess of fuel being delivered to the engine compared to the amount of air present.
