Co oznacza ten kod błędu?
The engine control module has detected that cylinder 4 is misfiring, and the misfire affects emissions. The fault is permanent, so it is present right now. The cause can be related to fuel or ignition, but air leaks and uneven compression can also produce the same fault.
Możliwe przyczyny
- Blocked or leaking injector
- Uneven compression in the engine
- Air leakage into the engine
- Faulty fuel pressure
- Low fuel level, or contaminated or incorrect fuel
- Repeated cold starts without the engine reaching normal temperature between them
Co możesz zrobić
- 1Check the engine oil level
- 2Read and note that the code refers to cylinder 4, clear it and road test
- 3Check the spark plug in cylinder 4 for damage to the insulation and for moisture in the plug well
- 4If you have a diagnostic tool: read the misfire counter for cylinder 4 at idle and see whether it rises
- 5Look for air leaks at the intake hoses and joints, especially where a hose may have come loose
- 6If the fault remains, have a workshop measure fuel pressure and compression with diagnostic equipment
Objawy, które możesz zauważyć4
- The engine misfires
- The engine is hard to start
- Performance is reduced
- Idle is uneven
Na co może wpływać usterka3
- Catalytic converter diagnosis is switched off
- Leak diagnosis is switched off
