Throttle Actuator Control Position Performance
2024-2024 Volvo EX30 Single Motor RWD
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.
