The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.
Certain police, fleet, and natural gas models may experience lower ball joint wear, requiring replacement of the front ball joints. Ford has issued a recall on certain vehicles for this condition. Please contact your local dealer for more information.
The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.
