Description: Turbocharger/Supercharger Wastegate Solenoid B Malfunction
- Check for any additional trouble codes that may be present and address them first.
- Inspect the wastegate solenoid wiring and connectors for damage, corrosion, or loose connections.
- Test the wastegate solenoid using a multimeter to ensure it is receiving power and ground signals properly.
- Verify the operation of the wastegate by manually actuating it to ensure it moves freely without obstruction.
- Check for vacuum leaks in the turbocharger/supercharger system that could affect wastegate operation.
- If applicable, use a scan tool to perform an active test on the wastegate solenoid to verify its functionality.
- If all tests pass but the code persists, consider replacing the wastegate solenoid as a last resort after confirming no other issues are present.
