Hva betyr feilkoden?

The code concerns the control valve in the variable intake system on bank 2. The ECM monitors the control signal to the damper, and the code is set when that signal is missing or too low.

Mulige årsaker

Poor contact or oxidation at the connector contacts
Open circuit in the signal wire
Open circuit in the supply or ground wire
Signal wire shorted to ground
Supply 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
2With the ignition off, check the connectors to the control valve for contact resistance and oxidation
3Use a multimeter to check that the signal wire has no open circuit and is not shorted to ground, and that the supply and ground wires are intact
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 merke3
