Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the EGR valve and performs an adaptation of it when needed. If the adaptation value is below the permitted level, meaning outside a predefined value, the fault code is stored. The fault can be caused by a short-circuited signal cable, a damaged position sensor or a damaged EGR valve. The code affects EGR control.
Mögliche Ursachen
- Signal cable short-circuited to ground
- Damaged position sensor
- Damaged EGR valve
Was Sie tun können
- 1Read the fault code, clear it and test drive the car to see whether it returns
- 2Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
- 3Check the signal cable to the position sensor for breaks and chafing; with a multimeter, confirm that the cable has no contact with ground (the body)
- 4If you have a diagnostic tool: read the EGR valve position in live data with the engine running and see whether the value is below what is expected
- 5Have a workshop with diagnostic equipment check the position sensor and the EGR valve and carry out the adaptation
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
