Most Reported On
P0350 is an OBD-II diagnostic trouble code meaning “Ignition Coil Primary/Secondary Circuit Malfunction.” This is a generic code indicating the engine computer detected a fault in an ignition coil's primary or secondary circuit. The computer monitors the coil control circuits that fire the spark plugs; when the expected electrical activity is missing or abnormal, this code sets. Because it does not always specify which coil, related cylinder-specific codes may also be present. It typically causes misfires, rough running, hesitation, hard starting, and reduced power. This code is most commonly reported on 2001-2011 Kia Rio, with repair costs ranging from $120 to $600.
