• Reinstall the connector
• Ignition on.

  Read off the boost pressure and atmospheric pressure.

  Check that the boost pressure sensor value does not deviate from the atmospheric pressure sensor value by more than 200 mbar. The atmospheric pressure sensor value is used as a reference value for this test.

Is the boost pressure sensor value within 200 mbar of the atmospheric pressure sensor value? 

• YES 

  OKAY:  Troubleshooting has been completed.

• NO 

  Refer to Checking the wiring

  Check that the boost pressure sensor value does not deviate from the atmospheric pressure sensor value by more than 200 mbar. The atmospheric pressure sensor value is used as a reference value for this test.

  Try a new boost pressure sensor if the boost pressure sensor value does not correspond to the atmospheric pressure sensor value.
