Co oznacza ten kod błędu?
The engine control module (ECM) counts misfires in cylinder 4 and stores the fault when the count exceeds a set limit while driving. The cylinder is not burning its fuel properly, which shows up as a rough idle and weaker throttle response. The fault should not be ignored, since unburnt fuel can damage the catalytic converter.
Możliwe przyczyny
- Blocked or leaking injector for cylinder 4
- Fault in the EGR system
- Uneven compression in cylinder 4
- Air leakage in the intake system
- Faulty fuel pressure or damaged fuel pipes
- Faulty ignition system or contaminated fuel
Co możesz zrobić
- 1Read out the fault code, erase it and road-test to see whether it returns
- 2Make sure the fuel tank has enough fuel and that the engine oil level is correct
- 3High-voltage ignition parts: keep clear while the engine runs. Check the cylinder 4 spark plug wells for moisture and damaged plug insulation
- 4Look for air leaks in the rubber hoses and intake pipe, especially at the connections. A stuck EGR valve can also cause the fault
- 5If you have a diagnostic tool, check in live data how the misfire counter for cylinder 4 behaves at idle compared with the other cylinders
- 6If the fault remains, have a workshop with diagnostic equipment measure the fuel pressure and compression and check the injector for cylinder 4
Objawy, które możesz zauważyć4
- The malfunction indicator lamp (MIL) is lit
- The engine misfires and does not fire on all cylinders
- The engine is difficult to start
- Poor performance and uneven idle
