2011 Ford Flex Check Engine Light Codes

The most common codes we see on a 2011 Ford Flex at Larry H. Miller Ford Lincoln Draper in Draper, UT include P0171/P0174 (fuel trim and vacuum/oxygen sensor issues), P0300–P0306 (misfires from ignition or fuel delivery), and P0420 (catalytic converter efficiency). If left unaddressed, a P0171 or P0174 can lead to poor fuel economy and increased emissions, costing more in fuel and potential catalytic repairs. Misfire codes can cause engine damage over time and escalate to costly repairs like cylinder head work. P0420 left unchecked may require an expensive catalytic converter replacement. Our certified technicians provide clear cost estimates and explain the immediate and long-term costs of postponing repairs. We use genuine Ford parts and offer efficient repairs designed to reduce return visits.
