Throttle Position Control Malfunction

on 2011 Porsche Cayenne 3.6L V6 · AWD

What this code means

The ECU detected that the electronic throttle body is not achieving the commanded position. The actual throttle opening deviates from the target by more than the allowable tolerance.

Symptoms

  • Check Engine Light
  • Reduced power mode
  • Throttle response sluggish
  • 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
  2. Clean throttle body
  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.
