Was bedeutet der Fehlercode?
The ECM follows the voltage from the rear oxygen sensor on bank 2, the cylinder row at the rear. The code is set when the sensor reads rich incorrectly, or when the voltage falls outside the range the ECM accepts.
Mögliche Ursachen
- Signal wire shorted to voltage
Was Sie tun können
- 1If you have a diagnostic tool: let the engine idle for a while, then read the fault status once the diagnosis is complete
- 2Do not use rust solvent spray or grease in the oxygen sensor connector
- 3Check the signal wire between the control module and the rear oxygen sensor on bank 2 with a multimeter, to see that it does not short to voltage
- 4If the fault remains after these checks: have a workshop replace the rear oxygen sensor
Symptome, die Sie bemerken können1
