What does code P0350 mean?

P0350 — Primary or secondary ignition coil circuit malfunction (generic). Engine isn't getting adequate spark — misfires, poor performance. Belongs to the powertrain.misfire system. Severity: critical.

What are the common causes of P0350?

Open primary or secondary coil winding; Damaged coil control wiring from ECM; Corroded or damaged coil connectors; Failed ECM coil driver transistor; Damaged ignition control module (where used)

Can I drive with code P0350?

Not recommended. Continued driving can damage the engine, transmission, or catalyst. Use a tow truck or take the shortest possible route to a workshop.

How do I diagnose P0350?

Read the code and freeze-frame with a scanner, check related-system errors, inspect the components listed (wiring, connectors, sensors). See the "How to diagnose" section above for the full step-by-step.

How do I clear code P0350?

The code can be cleared via an OBD-II scanner (e.g. ELM327 + the Car Diagnostics app): plug the adapter into the OBD port, go to Errors → Clear. If the underlying cause isn't fixed, the code will return within a few drive cycles.
