Code P0174 2002 Ford F150 Description
The P0174 code for a 2002 Ford F150 indicates that the engine is running too lean on Bank 2. This means that there is an imbalance in the air-fuel mixture being delivered to the cylinders on the side of the engine labeled as Bank 2. In a properly functioning system, the air-fuel mixture should be balanced in order to ensure efficient combustion. When the mixture leans out, there is not enough fuel present in relation to the air, which can lead to a variety of performance issues.
