Hva betyr feilkoden?
The code concerns the circuit to the control valve in the variable intake system on bank 2. The circuit is open, so the control signal to the valve is missing. The ECM monitors the control signal to the damper.
Mulige årsaker
- Poor contact or oxidation at the connector contacts
- Open circuit in the signal wire
- Open circuit in the supply wire
- Open circuit in the ground wire
- Signal wire shorted to ground
- Damaged damper actuator
Hva du kan gjøre
- 1Check that the fuses are intact and that the relevant functions of the car work, using the buttons, controls or a test drive
- 2With the ignition off, check that the connector to the control valve is secure
- 3Use a multimeter to check that the signal, supply and ground wires to the control valve have no open circuit, and that the signal wire is not shorted to ground
- 4If you have diagnostic equipment, activate the control valve and listen for a clicking sound
- 5If the wiring is intact but the fault remains, have a workshop check the damper actuator
Symptomer du kan merke4
- The car performs poorly and lacks power, especially at take-off
- The engine hesitates or surges during acceleration, during deceleration or at steady speed
- The engine stalls while driving
- The Check engine light comes on or behaves abnormally
