Question about 2002 Ford Explorer
Engine light on 2002 Explorer. engine code P1400 . What is differental press feedback EGR circuit low input? We replaced EGR valve, cleared the code and drove car 2 miles and light came back on.
This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.
