Was bedeutet der Fehlercode?
The ECM compares the front and rear oxygen sensors with each other and with their learned correction values. If the front sensor shows a lean mixture while the rear one shows a rich one, or the values drift too far apart, the code is stored. The fault can lie in the front or rear sensor circuit, and an exhaust leak can cause it.
Mögliche Ursachen
- Leakage in the exhaust system
- Oxygen sensor gives an incorrectly lean signal
- Damaged oxygen sensor
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look for air leaks in the exhaust system, such as cracks and leaking joints
- 3Look at the oxygen sensor connectors for oxidation and loose connections
- 4If there is no leak, have a workshop try replacing the oxygen sensors, since a damaged front or rear sensor can also cause the fault
Symptome, die Sie bemerken können1
- The malfunction indicator lamp (MIL) is lit
Was der Fehler beeinflussen kann2
- Oxygen sensor control is switched off
- Catalytic converter diagnostics are switched off
