P0353

Ignition Coil C Circuit Malfunction

The engine computer found a problem with ignition coil C or its wiring. This can cause a misfire, rough running, and poor engine performance.

Severity3/5 Moderate
Can I drive?⚠ With caution

You may be able to drive short distances, but the engine can run poorly and may misfire. Continued driving can damage the catalytic converter if the misfire is severe.

What It Means

P0353 means the powertrain control module detected an electrical fault in the ignition coil C circuit. This may be an open circuit, short circuit, high resistance, damaged coil, or a driver circuit problem inside the PCM. The fault can affect spark delivery to one cylinder and trigger a misfire code along with P0353.

FAQ

What does ignition coil C mean?

It usually refers to a specific ignition coil circuit assigned by the manufacturer. On some engines it may be the coil for one particular cylinder.

Can a bad spark plug cause P0353?

Yes, a badly worn or fouled spark plug can contribute to misfire and sometimes lead to coil circuit problems, but the code usually points first to the coil or wiring.

Will clearing the code fix it?

No. The code will return if the underlying electrical or ignition problem is still present.

Is it okay to keep driving with P0353?

Only for short, cautious trips if the engine runs normally. If it is misfiring or shaking, stop driving and fix the problem soon.
