* When prying with a flat-tip screwdriver, wrap it with protective tape to prevent damage.
* Before testing the sensor, check for climate control DTCs.

1. Sunlight Sensor - Test





1. Remove the sunlight sensor (A).

2. Turn the ignition switch to ON (II).

3. Measure the voltage between (+) probe on terminal No. 2 and (-) probe on terminal No. 4 with the connector connected.

NOTE: The voltage readings will not change under the light of a flashlight or a fluorescent lamp.

Voltage should be:
* 3.56 V with no sunlight or the sensor covered up
* Less than 3.56 V with sunlight on the sensor
(depending on sunlight intensity)

4. If the voltage is not as specified, replace the sunlight sensor.
