Co oznacza ten kod błędu?

The control module monitors the EGR valve function and sets the fault if the signal from the position sensor is too high. The causes may be poor contact in the connections, an open circuit in the supply or signal wire, a signal wire shorted to voltage, or a damaged EGR valve.

Możliwe przyczyny

Contact resistance, oxidation or poor contact in the connections
Open circuit in the supply or signal wire
Signal wire short-circuited to voltage
Damaged EGR valve

Co możesz zrobić

1Switch off the ignition and check the connections to the EGR valve for poor contact, contact resistance and oxidation
2Look for chafing on the signal wire near the EGR valve, and use a multimeter to check that it is not shorted to voltage
3Also use a multimeter to check that the supply to the position sensor has no open circuit
4If you have a diagnostic tool, read the EGR position sensor value in live data at idle and see whether it stays consistently high
5If the fault remains, have a workshop with diagnostic equipment check the EGR valve
