P0352 on Toyota: How to Diagnose & Fix
Ignition Coil B Primary/Secondary Circuit Malfunction
1 Toyota model · 1 documented issue · $60-$350 repair
P0352 on Toyota by model: symptoms, diagnosis and fix
The individual coil-on-plug ignition coils fail from age and heat cycling on high-mileage Corollas, causing a cylinder misfire. This sets P0351-P0354 (coil circuit) and/or P0300-P0304 (misfire). OEM coil PN 90919-02239 is the common part for 2000-2008 1ZZ-FE cars. A failing coil produces rough idle, a flashing check engine light under load, and a raw-fuel smell; a chronic misfire can also foul the catalytic converter.
Common Symptoms
- Rough idle and shaking
- Flashing check engine light under acceleration
- Loss of power / hesitation
- Raw fuel smell from exhaust
How to Fix
Identify the misfiring cylinder from the codes and swap that coil to a neighboring cylinder to confirm the fault follows the coil. Replace the failed coil (and inspect/replace worn spark plugs as a set on high-mileage cars). OEM 1ZZ-FE coil PN 90919-02239 (~$40-70 each); Denso 673-1303 and other quality aftermarket units cross-reference. Use OEM/Denso-grade coils, as cheap coils commonly re-fail. Clear codes after repair.

Frequently asked questions
What does P0352 mean on a Toyota?
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 Toyota it is documented across 1 model: Corolla.
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 Toyota?
Published repair estimates on Toyota range from $60 to $350 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.
