Was bedeutet der Fehlercode?
The engine control module (ECM) adjusts the exhaust camshaft position with a changeover valve on bank 1, the cylinder row nearest the front. The fault code is set when the control signal to the valve is too low. Common causes are poor contact in the connectors or a signal or supply wire shorted to ground.
Mögliche Ursachen
- Contact resistance in the connectors
- Signal wire shorted to ground
- Voltage supply wire to the valve shorted to ground
- Damaged exhaust camshaft changeover valve
Was Sie tun können
- 1Check that the fuse for the valve circuit is intact. If it has blown, use a multimeter to check whether the wire is shorted to ground
- 2Check the connector at the changeover valve for loose connections, oxidation and contact resistance
- 3Use a multimeter to check that the wires to the valve are not shorted to ground, with the connectors disconnected
- 4Measure the valve resistance if the connector and wiring are in order, or have a workshop do it
- 5After the repair, check that the fault code does not come back
Symptome, die Sie bemerken können4
- Check engine lamp (MIL) lights up
- Uneven idle
- Poor performance and lack of power, especially when pulling away
- The engine can stall while driving, during acceleration, deceleration or at steady speed
Was der Fehler beeinflussen kann1
- Exhaust camshaft control is switched off
