Was bedeutet der Fehlercode?
The engine control module (ECM) adjusts the fuel injection from the lambda sensor reading to keep the mixture at λ=1. The code is set when that adjustment has to be made close to its maximum in the lower or upper part-load range, meaning the mixture runs too lean. The fault may lie in a leak, the mass air flow sensor, the fuel pressure, the lambda sensor or the injectors.
Mögliche Ursachen
- Air leakage in the intake system before the turbo
- Damaged mass air flow (MAF) sensor
- Air leakage in the exhaust system
- Low fuel pressure
- Damaged heated oxygen sensor (HO2S)
- Damaged or incorrect type of injectors
Was Sie tun können
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Look for leaks between the mass air flow sensor and the turbocharger, and check the hoses for cracks and loose clamps
- 3Check the exhaust system for air leakage
- 4Check that the mass air flow sensor is not damaged or dirty, and that its connectors and wiring are intact
- 5Think back on how the car has been refuelled; fuel with too high an ethanol content can cause this code, so have a workshop check the ethanol calculation
- 6Replace the lambda sensor if nothing above cures the fault, since a damaged lambda sensor can also set this code
Symptome, die Sie bemerken können1
- The malfunction indicator lamp lights up or behaves abnormally
