• Ignition off
• Check the boost pressure sensor connector. Check for contact resistance and oxidation
• Reinstall the components, reconnect the connectors etc.
• Ignition on.

  Read off the boost pressure and the atmospheric pressure.

  The difference in pressure must not be greater than 140 hPa.

  If the difference is less than 140 hPa, the cause of the fault was loose connections in the connector.

Is the difference between the pressures less than 140 hPa? 

• YES 

  OKAY:  Troubleshooting has been completed.

• NO
