• Ignition off
• Check the boost pressure sensor connector. Check for contact resistance and oxidation.
  NOTE:

  The intake air temperature (IAT) sensor is integrated in the boost pressure sensor

• Reinstall the components, reconnect the connectors etc.
• Ignition on
• Read off the intake air temperature (IAT).

  Check that the intake air temperature (IAT) is within its permitted range. If the intake air temperature (IAT) is now within its permitted range, the fault was caused by loose connections in the connector.

  Other information: 

  • To access or replace the intake air temperature (IAT) sensor, see Temperature and pressure sensor, replacing .
