    • Record the turbocharger actuator arm position.

    Does the turbocharger actuator arm change position when commanded? 

    Yes No
    The system is operating correctly at this time.
    RETURN to SYMPTOM CHARTS for further direction.    		 INSTALL a new Turbocharger Actuator.
    REFER to the appropriate Engine Controls - Fuel Charging And Controls article. CARRY OUT the Reset And Clear The Specified Function Turbo System and MAF Sensor on the scan tool.
    REFER to CLEAR THE CONTINUOUS DIAGNOSTIC TROUBLE CODES (DTCS) AND RESET THE EMISSION MONITORS INFORMATION IN THE POWERTRAIN CONTROL MODULE (PCM) .

  11. AK11 CHECK FOR CORRECT TURBOCHARGER ACTUATOR OPERATION 
    • Visually inspect for:
      • pushed out pins
      • corrosion
    • Connect the turbocharger actuator connector and make sure it seats correctly.
    • Carry out the PCM self-test and verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new Turbocharger Actuator. REFER to the appropriate Electronic Engine Controls article.
    CARRY OUT the Reset And Clear The Specified Function Turbo System on the scan tool. REFER to CLEAR THE CONTINUOUS DIAGNOSTIC TROUBLE CODES (DTCS) AND RESET THE EMISSION MONITORS INFORMATION IN THE POWERTRAIN CONTROL MODULE (PCM) .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
