Inspection
1.

Turn the ignition switch OFF.

2.

Disconnect ambient temperature sensor.

3.

Check the resistance of ambient temperature sensor between terminal “+” and “-” whether it is changed by changing of the ambient temperature.

If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.

5.

If the problem is corrected, replace the ambient temperature sensor.
