Code P0175 1998 Ford F150 Description

The P0175 code for a 1998 Ford F150 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 means that there is too much fuel being injected into the cylinders on that side, leading to a rich condition. A rich air-fuel mixture can result in poor fuel economy, reduced engine performance, increased emissions, and potential damage to the catalytic converter over time.
