Co oznacza ten kod błędu?
The engine control module (ECM) adjusts injection from the lambda sensor reading. The code is set when that adjustment has to be made close to its maximum in the lower or upper part-load range, and the signal is too high. The fault may lie in the fuel, a leak in the exhaust system, the fuel pressure, the lambda sensor or the injectors.
Możliwe przyczyny
- Too high an ethanol content in the fuel
- Air leakage in the exhaust system
- Low fuel pressure
- Damaged heated oxygen sensor (HO2S)
- Damaged or incorrect type of injectors
- Incorrectly calculated ethanol content
Co możesz zrobić
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Check the exhaust system for air leakage
- 3Have a workshop measure the fuel pressure and check that it is not too low
- 4Think back on how the car has been refuelled; if the fuel may have too high an ethanol content, have a workshop check the ethanol calculation
- 5Check that the injectors do not leak, and have a workshop do this if you lack the right equipment
- 6Replace the lambda sensor if nothing above cures the fault, since a damaged lambda sensor can also set this code
Objawy, które możesz zauważyć4
- The malfunction indicator lamp (MIL) is lit
- The car hesitates or surges when accelerating
- The idle is uneven
- The engine does not start and only cranks
