A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Valve actuator or its vacuum hose
- The flap sticks because of carbon or the linkage is broken
- Valve position sensor
What you can do yourself
- The valve switches the intake runners to suit engine speed. With this fault the engine pulls less well at low or high revs, but you can drive.
- Check the valve connector and its vacuum hose, if it has one.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
