Code P0175 2018 Chevrolet Silverado Description
The P0175 code on a 2018 Chevrolet Silverado indicates that the fuel trim system on bank 2 is running rich. This means that the engine control module (ECM) has detected that the air-fuel mixture is too rich on the second bank of cylinders. The fuel trim system is responsible for adjusting the air-fuel mixture to maintain optimal combustion and engine performance. When the system is running rich, it means there is an excess of fuel in the mixture, which can lead to poor fuel economy, reduced power, and increased emissions.
