5% of P0360 cases are fixed by replacing this part
Check These First (Before Buying Parts)
- Visually inspect the ignition coil for cylinder 3 for any cracks, burn marks, or signs of physical damage.
- Ensure the electrical connector to the cylinder 3 ignition coil is securely attached and free of corrosion.
How to Diagnose P0360
- 1Visually inspect the ignition coil and wiring for cylinder 3 for any obvious damage, cracks, or loose connections.
- 2Swap the ignition coil from cylinder 3 with a coil from a different cylinder (e.g., cylinder 1). If the code changes to P0361 (or P0351 for cylinder 1), the coil is faulty.
- 3Remove and inspect the spark plug from cylinder 3 for wear, fouling, or damage. Replace if necessary.
- 4Use a multimeter to test the resistance of the ignition coil and check for proper voltage and ground at the coil connector.
- 5If the issue persists after checking coil, plug, and wiring, consider further diagnosis of the PCM, though this is uncommon.

Frequently Asked Questions
What does P0360 mean?
P0360 indicates a malfunction in the primary or secondary electrical circuit of the ignition coil for cylinder 3. This means the engine computer isn't seeing the correct electrical signal from or to that specific coil.
Can I drive with P0360?
Yes, for short trips only. You can drive your vehicle to a repair shop or home, but limit driving. Continued driving with a misfire can send unburned fuel into your catalytic converter, causing expensive damage over time.
Will P0360 clear itself?
No, P0360 will not clear itself. The underlying issue causing the circuit malfunction must be diagnosed and repaired. Once the repair is complete, you will need to clear the code with an OBD-II scanner.
How do I fix P0360 myself?
Start by visually inspecting the ignition coil and its wiring for cylinder 3. If no obvious damage, swap the cylinder 3 coil with another cylinder's coil. If the misfire moves, replace the faulty coil. If not, inspect and replace the spark plug for cylinder 3. Check the coil's electrical connector and wiring for damage or corrosion.
How much does it cost to fix P0360?
DIY repair costs for P0360 typically range from $35-$220, primarily for a new ignition coil and possibly a spark plug. Professional repair at a shop usually costs $150-$400, covering parts and labor.
P0360 keeps coming back - why?
If P0360 keeps returning, it indicates the initial repair did not address the root cause. This often happens if you only replaced the coil but the spark plug was also bad, or if there's an intermittent wiring issue, or a rare PCM fault that was overlooked.
Will P0360 fail emissions/smog test?
Yes, P0360 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and a misfire directly impacts exhaust emissions.
What's the difference between P0360 and P0303?
P0360 specifically indicates a problem with the electrical circuit of the ignition coil for cylinder 3. P0303 indicates a general misfire detected in cylinder 3, which could be caused by the coil, spark plug, fuel injector, or even engine mechanical issues. P0360 points directly to the coil's electrical function.
P0360 on Honda Civic?
On Honda Civics, P0360 is most commonly caused by a failing ignition coil for cylinder 3. These coils can degrade over time, especially with higher mileage. It's a straightforward replacement, often done with the spark plug.
Questions to Ask Your Mechanic
Did you test the resistance of the ignition coil for cylinder 3?
Good answer: Yes, the primary and secondary resistance were out of specification, indicating an internal coil fault.
Did you check the wiring and connector to the cylinder 3 ignition coil for continuity and corrosion?
Good answer: Yes, we checked for voltage, ground, and signal at the connector, and inspected the wiring for any breaks or shorts.

Beginner-friendly - Replacing an ignition coil and spark plug for a single cylinder is a common and accessible DIY repair for most vehicle owners with basic tools.
Cost of Waiting
Continued misfires from P0360 send unburned fuel into your exhaust system. This can rapidly overheat and destroy your catalytic converter, turning a $35-$220 ignition coil job into a $800-$2,500 catalytic converter replacement.
While You're In There...
It's directly related to the coil's function and often wears out at a similar rate. Replacing it with the coil prevents repeat labor for a potential future misfire.
Applying dielectric grease to the coil boot helps seal out moisture, prevents corrosion, and ensures a good electrical connection, extending the life of the new coil.
If replacing the spark plug, applying anti-seize to the threads prevents the plug from seizing in the cylinder head, making future replacements easier.
Tools You'll Need
- OBD-II scanner
- Socket wrench set
- Spark plug socket (if replacing plug)
- Dielectric grease
- Anti-seize compound (for spark plug threads)
- Multimeter (for advanced diagnostics)
P0360 is a common ignition system code. Most repairs involve replacing a single ignition coil or spark plug, which is a straightforward fix that will get your engine running smoothly again.

Your Next Steps
Step 1: Visually inspect the ignition coil and wiring for cylinder 3. Look for any obvious damage or loose connections.
Step 2: If no visual issues, swap the ignition coil from cylinder 3 with a known good coil from another cylinder. Clear the code and see if the misfire code follows the coil. If it does, replace the coil.
Step 3: If swapping the coil does not resolve the issue, remove and inspect the spark plug for cylinder 3. Replace it if it's worn, fouled, or damaged.
