Was bedeutet der Fehlercode?
The ECM does not receive correct values when it learns the end positions of the EGR valve, or the learning does not succeed. Although the code is named as a low signal, the condition concerns that learning.
Mögliche Ursachen
- Loose connection, contact resistance or oxidation in the connections

- 2Check the connections to the EGR valve for loose contacts, contact resistance and oxidation
- 3Use a multimeter to check that the signal cable to the EGR valve is not short-circuited to ground
