How to diagnose and fix P0352: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Volkswagen Jetta · 2008–2021
The ignition coils on 2.0T engines can fail, causing misfires, rough running, and check engine lights. This is especially common on older coils and when using aftermarket spark plugs. High boost applications accelerate coil wear.
Common Symptoms
- Misfire codes (P0300-P0304)
- Rough idle
- Loss of power
- Flashing check engine light
- Poor fuel economy
How to Fix
Replace failed ignition coil(s). Consider replacing all four coils at once as they tend to fail at similar mileage. Use OEM or quality aftermarket coils (Bosch, Eldor). Replace spark plugs at same time with proper gap.

Volkswagen Rabbit · 2006–2009
The 2006-2009 Rabbit with the 2.5L 5-cylinder engine (07K) is notorious for premature ignition coil pack failures. The individual coil-on-plug packs crack internally from heat cycling, causing misfires and rough running. The 5-cylinder layout requires all 5 coils to function properly for smooth operation, and a single failed coil creates noticeable vibration. Coils typically fail between 40,000-80,000 miles.
Common Symptoms
- Engine misfires (flashing check engine light)
- Rough idle and vibration
- Loss of power
- Check engine light with codes P0300-P0305
- Poor fuel economy
- Stumbling during acceleration
How to Fix
Replace all 5 ignition coil packs at once (VW part# 07K-905-715-F or Bosch equivalent). Replace spark plugs simultaneously with NGK ILZKR7B-11S or Bosch FR7NPP332. This is a DIY-friendly job requiring only basic tools and 30-45 minutes. Do not replace just the failed coil - the others are the same age and will follow.

Honda Fit · 2007–2020
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?
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.
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?
Repair costs for P0352 range from $60 to $1,000, depending on the vehicle and root cause.
