What does this fault code mean?

The engine control module checks the signal wire to the control valve at the inlet and stores the code when the signal is too low. The control valve operates the damper in the intake pipe, and the fault can lie in the connectors, the signal wire, the power supply or the valve itself.

Possible causes

Poor contact, contact resistance or oxidation in the connectors
Open circuit in the signal wire
Open circuit in the power supply
Signal wire shorted to ground
Damaged control valve at the inlet

What you can do

1Check that the damper in the intake pipe has not stuck
2Check the connectors at the control valve and the control module for play, contact resistance and oxidation
3Use a multimeter to check that the signal wire is not broken and not in contact with ground
4Have a diagnostic tool? Activate the control valve and check that the damper moves
5If the connectors and wiring are sound but the fault remains, have a workshop check the control valve
