• Reinstall components, reconnect connectors etc.
• Ignition on.

  Read off the outside temperature in Volt. Check that it is correct according to the table values:Intake air temperature (IAT) sensor inlet .

  If the temperature is now OK it means that the fault was caused by loose connections in the connector.
