Sunload Sensor Inspection

Remove sunload sensor. Refer to SUNLOAD SENSOR REMOVAL AND INSTALLATION .
Light over the sensor vertically with an incandescent light of approximately 100 watt.
The distance between the sensor and the light should be approximately 100 mm (3.94 in.).
Measure the voltage between the terminals with the (+) probe on the terminal "a" and the (-) probe on the terminal "b".
Make sure if the voltage is approximately 0.38 - 0.42 V. If not, replace the sensor with the new one.
