Co oznacza ten kod błędu?

The fault code is stored when the engine control module (ECM) detects misfires on several cylinders that can damage the catalytic converter. Unburned fuel that reaches the exhaust system can cause the catalytic converter to overheat. The code is part of a misfire series and does not replace the cylinder code that shows which cylinder is affected.

Możliwe przyczyny

Poor fuel quality, for example summer fuel in winter
Clogged crankcase ventilation
Damaged VVT unit
Uneven compression
Incorrectly calculated ethanol content
Low fuel level

Co możesz zrobić

1This code has no fault tracing of its own; read the cylinder-specific codes to see which cylinders misfire
2Check that the fuel level is sufficient and that the fuel suits the season
3Check the crankcase ventilation hoses and valve for clogging
4If you have a diagnostic tool: read the misfire counters for each cylinder in live data with the engine running and see whether any of them stands out
5Have a workshop with diagnostic equipment check the VVT unit, the compression and the fuel pressure

Objawy, które możesz zauważyć5

The engine is hard to start and cranks slowly
Uneven idle
The engine feels short of power
The engine jerks or hesitates when driven
The Check engine light lights up or behaves abnormally

Na co może wpływać usterka3

The catalytic converter diagnosis is switched off
Rear oxygen sensor control is switched off
