Turbocharger Wastegate Actuator Position

The computer is monitoring the wastegate, which controls how much exhaust goes into the turbo. If the actuator position isn't where the system expects, it sends this code.

The control module expects the wastegate position to vary as engine load changes. If it sees a steady voltage that doesn't correspond to the expected actuator position, it triggers a fault.

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

1. 11. Inspect wiring and connectors to the wastegate actuator for any signs of damage, corrosion, or loose connections. Caution: ensure the vehicle is off and the key is out.
2. 22. Check the vacuum supply to the actuator (if applicable). Ensure that any vacuum hoses are intact and there is sufficient vacuum pressure (generally expected to be about 20 inHg).
3. 33. Use a scan tool to observe the actual position of the wastegate actuator compared to specified values. If it's out of range, proceed to next step.
4. 44. Manually test the wastegate actuator by applying known voltage (typically between 5V-12V). Ensure the actuator moves freely. If it doesn’t move, replace the actuator.
5. 55. If actuator is moving but readings are still off, suspect turbocharger assembly issues or further internal faults.

• Faulty wastegate actuator
• Wiring issues or bad connectors
• Faulty turbocharger assembly
• Vacuum supply issues (if applicable)
