OBD2 Error Code P0353: How to Fix It

Q: What causes OBD2 error code P0353?

P0353 is typically caused by a faulty ignition coil, damaged wiring to the coil, loose electrical connections, a bad spark plug, or rarely, a defective engine control module (PCM).

Q: Can I drive with P0353 error code?

You should avoid driving with P0353 as it indicates ignition system problems that can cause engine misfires, damage to the catalytic converter, and poor fuel economy. Get it diagnosed and repaired promptly.

Q: How much does it cost to fix P0353?

Repair costs typically range from $100-300 if only the ignition coil needs replacement, or $150-400 if both coil and spark plug need replacement. Wiring repairs may cost more depending on extent of damage.

Q: Will P0353 clear itself?

P0353 will not clear itself as it indicates a hard fault in the ignition system. The code will remain until the underlying problem is repaired and codes are manually cleared with an OBD2 scanner.

Q: What happens if I ignore P0353?

Ignoring P0353 can lead to engine misfires, reduced power, poor fuel economy, rough idling, potential catalytic converter damage, and possible engine damage from unburned fuel entering the exhaust system.
