Code P0174 2011 Ford Fusion Description
The P0174 code for a 2011 Ford Fusion indicates that the fuel injection system on bank 2 is running too lean. This means that there is an imbalance in the air-fuel mixture being delivered to the engine. In a properly functioning system, the engine control module (ECM) constantly monitors the air-fuel ratio and adjusts it to ensure optimal combustion. When the ECM detects that there is too much air and not enough fuel in the mixture, it triggers the P0174 code.
