Was bedeutet der Fehlercode?

The ECM operates the variable intake system and monitors the control signal to the actuator for the intake manifold tuning valve on bank 1. The code is set when that control signal is missing, and the circuit may be open or shorted to ground.

Mögliche Ursachen

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 actuator

Was Sie tun können

1With the ignition off, check that the connectors to the actuator and to the engine control module are secure, free from contact resistance and oxidation
2Use a multimeter to check that the signal, supply and ground wires to the actuator have no open circuit, and that the signal wire is not shorted to ground
3Check that the fuses are intact and that the relevant functions of the car work, using the buttons, controls or a test drive
4If the wiring is intact, have a workshop check the actuator
5Clear the fault code after the repair and check that it does not return

Symptome, die Sie bemerken können4
