• Ignition off.
• Check boost pressure sensor connector for contact resistance and oxidation according to Contact resistance and oxidation .
• Reinstall components, reconnect connectors etc.
• Ignition on.
• Read boost pressure and atmospheric pressure.
• The difference in pressure should not be greater than 140 hPa.

  If the difference is less than 140 hPa it means that the cause of the fault has been loose connections in the connector.
