Code P2066 2011 Ford Fusion Description

The P2066 diagnostic trouble code for a 2011 Ford Fusion indicates an issue with the Fuel Level Sensor 'B' performance. The fuel level sensor is a crucial component of the vehicle's fuel system, responsible for measuring the amount of fuel in the tank and sending this information to the vehicle's engine control module (ECM). This data is used by the ECM to calculate fuel consumption, adjust air-fuel mixture, and optimize engine performance.
