1 Honda model · 1 documented issue · $80-$300 repair
P0352 on Honda by model: symptoms, diagnosis and fix
Ignition coil packs can fail causing engine misfires. Usually one coil fails at a time. Engine misfire, rough idle, check engine light with misfire codes. Bosch ($50-80 each) or Denso ($60-90 each) replacement coils recommended on FitFreak. Replace all four at once ($200-300) to prevent future failures and repeated labor costs. DIY installation very easy (bolt on, connector plug) - saves $100-200 in shop labor.
Common Symptoms
- Engine misfire
- Rough idle
- Check engine light with misfire codes P0300-P0308
- Reduced fuel economy
- Hesitation during acceleration
How to Fix
Test coil pack resistance with multimeter before replacing to confirm failure. Replace failed ignition coil pack. Consider replacing all four if one fails (preventive measure, $200-300 for all four). Bosch ($50-80 each) or Denso ($60-90 each) recommended. DIY installation very easy.

Frequently asked questions
What does P0352 mean on a Honda?
P0352 stands for "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. On Honda it is documented across 1 model: Fit.
What are the most common causes of P0352?
The most common causes of P0352 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0352 on a Honda?
Published repair estimates on Honda range from $80 to $300 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
