Diagnostic help
The temperature sensor reading can be obtained on
an ISAT scan tool.
- Turn the ignition switch to the ON position and
then back to the OFF position.
- Connect an ISAT scan tool.
- Select "READ FUNCTIONS".

If the temperature sensor is in perfect working order
the ISAT scan tool should show the current intake air
temperature.
