Was bedeutet der Fehlercode?
The oxygen sensor gives the engine control module information about the fuel and air mixture. The code is set when the module detects that the sensor's calibration signal is wrong, here too low. The fault can only be checked when the sensor is calibrated, which is a workshop task.
Mögliche Ursachen
- The signal lead is short-circuited to ground
Was Sie tun können
- 1Check the connector to the oxygen sensor for loose connections and damage
- 2With the ignition off, use a multimeter to check that the signal lead from the oxygen sensor is not short-circuited to ground
- 3Look for chafing or pinch damage on the signal lead where it may have touched ground
- 4Have a workshop check the oxygen sensor during calibration if the fault remains after the wiring check
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
- The engine control module uses the last measured value
