Throttle Actuator Control Motor Current Range/Performance
The current draw of the throttle motor lies outside the expected range — either much higher (binding plate) or much lower (worn brushes, open winding) than calibrated.
Affected components
- Throttle actuator motor
- Throttle body
Common causes
- High likelihood: Plate binding from carbon
- Medium likelihood: Motor windings aged or open
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- Check engine light on
- Reduced throttle response, possible limp mode
- Hesitation or surging
- Idle too high or too low
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
- Reduced-power or limp mode may occur
