Rough Idle Caused By EGR Sensor Sticking on Ford F-150 Heritage

Problem Description and Possible Solution

The Ford F-150 Heritage is known for intermittent rough idling, which may be accompanied by illumination of the check engine light, and poor fuel mileage.

This may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open, and diagnostic testing must be conducted.

The EGR valve and sensor must be replaced together to correct this concern.
