Code P0175 2009 Toyota Camry Description

The diagnostic trouble code P0175 in a 2009 Toyota Camry indicates that the engine control module (ECM) has detected a rich air-fuel mixture on bank 2 of the engine. This means that there is too much fuel being injected into the combustion chamber compared to the amount of air present, leading to a condition known as "running rich." In a properly functioning engine, the air-fuel mixture should be balanced at a specific ratio for optimal combustion and performance. When the mixture becomes too rich, it can result in a variety of issues that affect the vehicle's performance, fuel efficiency, and emissions.
