Throttle Actuator Control Position Performance
2003-2014 Volvo XC90 3.2L I6
Description
The ECM detected that the electronic throttle actuator is not achieving or maintaining the commanded throttle position within acceptable performance tolerances over time.
Symptoms
- Check Engine Light
- Sluggish throttle response
- Intermittent reduced power mode
- Unstable idle
Common Causes
- Worn throttle body actuator motor
- Carbon buildup causing drag
- Throttle position sensor drift
- Wiring intermittent fault
- Throttle body return spring weak
Diagnostic Steps
- Monitor commanded vs actual throttle position over time
- Clean throttle body
- Perform throttle adaptation
- Test throttle motor current draw
- Inspect throttle body for mechanical wear
Repair Notes
Clean the throttle body and perform adaptation; replace if mechanical wear is found.
