P0352 on Kia
Ignition Coil B Primary/Secondary Circuit Malfunction
P0352 on Kia vehicles indicates ignition coil b primary/secondary circuit malfunction. Au7o has documented this code across 1 Kia model — most commonly on Rio. 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. Typical repair costs on Kia range from $120 to $600, depending on the specific model and root cause.
Common Causes of P0352
- •Failed ignition coil 'B'
- •Damaged wiring or corroded connector at the coil
- •Open or short in the coil primary/secondary circuit
- •Worn or fouled spark plug increasing coil stress
- •Poor power or ground supply to the coil
- •Faulty ignition control circuit/driver in the ECM (less common)

- Ignition Coil and Plug Wire Failure Causing Misfire, Hesitation, and Check Engine Light2001-2011
Across both generations of Rio, owners frequently report ignition-related misfires caused by failing coil packs, deteriorated plug wires on earlier cars, or worn spark plugs. The problem typically shows up as rough idle, hesitation under load, flashing MIL, and poor fuel economy. It is common enough in owner complaints and repair forums to be considered a recurring Rio issue, especially as these cars age.
