  • Engine may stall
  • EPC warning light on

Common Causes

  • Carbon buildup on throttle plate
  • Faulty throttle body motor
  • Throttle position sensor fault
  • Wiring issue
  • ECU throttle driver failure

Diagnostic Steps

  1. Perform throttle body adaptation/basic setting

  3. Test throttle motor by commanding positions
  4. Check wiring and connector
  5. Monitor commanded vs actual throttle position

Repair Notes

Clean throttle body and perform adaptation; replace if motor has failed.
