2011 Ford Focus Problems
RepairPal has identified the most common problems with the 2011 Ford Focus based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Many customers state that whule driving their vehicle, the engine will hesitate, stumble, or lose power. In more severe cases, the EGR valve can be physically damaged. In all cases, the check engine light will be illuminated, and diagnostic trouble codes will be stored in the PCM.
Diagnosis of the issue has concluded the differential pressure feedback EGR sensor (DPFE) is at fault many times, and incorrectly measures exhaust gas re-circulation (EGR) pressure.
Correction of the issue requires a diagnostic scan, identification of the faulty sensor, and, ultimately, the sensor and EGR valve may require replacement. In some models, the DPFE sensor is integrated into the EGR valve, and must be replaced together.
As the motor mounts break down or wear, additional noise and vibration may be noted when the vehicle is at idle. Replacement of the motor mounts would be required to remedy this condition.
