Code P2097 Honda Description
The P2097 diagnostic trouble code for Honda vehicles indicates that the post catalyst fuel trim system on bank 1 is too rich. This means that there is an excessive amount of fuel being delivered to the engine, resulting in a rich air-fuel mixture. The post catalyst fuel trim system is responsible for monitoring and adjusting the amount of fuel being injected into the engine after it has passed through the catalytic converter. When this system detects that the fuel mixture is too rich, it will trigger the P2097 code.
