P0352: Ignition Coil B Primary/Secondary Circuit Malfunction
10 vehicles · 8 makes · $60-$1,000 repair
Most Reported On
P0352 is an OBD-II diagnostic trouble code meaning “Ignition Coil B Primary/Secondary Circuit Malfunction.” This is an ignition/engine code. Each ignition coil takes the car's low battery voltage and steps it up into the high-voltage spark that fires a spark plug. P0352 means the engine computer detected a problem in the primary or secondary circuit of ignition coil 'B' — it isn't getting the proper electrical signal back when the coil is commanded to fire. This often causes a misfire, rough running, hesitation or reduced power, and if left unaddressed can lead to unburned fuel damaging the catalytic converter. This code is most commonly reported on 2008-2021 Volkswagen Jetta, 2006-2009 Volkswagen Rabbit, and 2007-2020 Honda Fit, plus 7 other vehicles, with repair costs ranging from $60 to $1,000.
