Checking the technical condition
1. Turn off the ignition.
2. Disconnect the ambient temperature sensor.
3. Check the change in resistance between terminals 1 and 2 of the ambient air temperature sensor.
Note: Specifications:
4. If the measured resistance value is not within specifications, substitute a known-good ambient air temperature sensor and check for proper operation.
5. If the problem is corrected, replace the ambient air temperature sensor.
Replacement
1. Disconnect the negative battery terminal.
2. Disconnect the connector and remove the outdoor temperature sensor (A).
3. Install in the reverse order of removal.
