Idle Control Valve Position Circuit
2001-2005 BMW 330i E46 3.0L I6
Description
The DME detected a malfunction in the idle control valve (ICV) position circuit. The ICV regulates airflow at idle to maintain a stable engine speed. On BMW engines, this is commonly caused by a sticking or carbon-fouled valve.
Symptoms
- Rough or unstable idle
- Engine stalling at idle
- Idle speed too high or too low
- Check Engine Light
Common Causes
- Carbon-fouled idle control valve
- Faulty idle control valve motor
- Wiring issue to ICV
- Vacuum leak affecting idle
- DME output driver failure
Diagnostic Steps
- Test ICV operation by commanding open/close with scan tool
- Measure ICV motor resistance
- Clean ICV with throttle body cleaner
- Check vacuum lines around throttle body
- Inspect ICV wiring
Repair Notes
Clean the idle control valve with throttle body cleaner; replace if cleaning does not resolve the issue.
