Code P0175 2006 Toyota Camry Description

When the diagnostic trouble code P0175 appears on a 2006 Toyota Camry, it indicates that the engine control module (ECM) has detected a rich air-fuel mixture on bank 2 of the engine. Bank 2 typically refers to the side of the engine that does not contain cylinder 1. This rich condition means that there is too much fuel being injected into the combustion chamber relative to the amount of air present. This can lead to a variety of issues, including decreased fuel efficiency, reduced engine performance, increased emissions, and potential damage to the catalytic converter.
