Code P0174 2006 Ford Fusion Description
The P0174 code for a 2006 Ford Fusion indicates that the fuel injection system on bank 2 is running too lean. In an ideal situation, the air-fuel mixture in the engine should be balanced, with the correct ratio of air to fuel for optimal combustion. However, when the system is running too lean, it means that there is too much air and not enough fuel being delivered to the engine. This can lead to a variety of issues that can impact the vehicle's performance and overall operation.
