Co oznacza ten kod błędu?

The catalytic converter can overheat if cylinder 4 misfires so that unburned fuel reaches the exhaust system. The engine control module (ECM) sets the fault code when such misfires are detected early after the engine starts.

Możliwe przyczyny

Poor fuel quality
Clogged or leaking injection valve
Incorrect fuel pressure
Air leak
Uneven compression
Incorrectly calculated ethanol content

Co możesz zrobić

1Read the fault codes; camshaft-related codes should be traced first
2Check that the fuel suits the season and that the fuel level is sufficient
3Check that the intake system and the crankcase ventilation do not leak or are not clogged
4If you have a diagnostic tool: read the misfire counter for cylinder 4 in live data with the engine running and see whether it is raised compared with the other cylinders
5Have a workshop with diagnostic equipment check the injection valve and the VVT unit on cylinder 4, and the compression
