Was bedeutet der Fehlercode?
The code concerns EGR control, that is exhaust gas recirculation, and is set when the engine control module has registered a fault in the EGR valve or its wiring that causes incorrect EGR control. The causes include poor contact, a short or open circuit in the wiring, and a valve that sticks or is damaged.
Mögliche Ursachen
- Poor contact, contact resistance or oxidation at the EGR valve connectors
- Short circuit to supply voltage in the wiring to the EGR valve
- Short circuit to earth in the wiring to the EGR valve
- Open circuit in the wiring to the EGR valve
- The EGR valve seizes or has jammed
- Damaged EGR valve
Was Sie tun können
- 1Check that the fuses are intact.
- 2Go through the connectors at the EGR valve and make sure they are secure and clean.
- 3Look for breaks and chafed wires to the EGR valve, which may have touched earth or supply voltage.
- 4Check that the EGR valve is not stuck from soot or dirt.
- 5Have a workshop check the valve with diagnostic equipment. If it is damaged it needs replacing.
