Lumina V6-3.1L VIN J (2000)
Ambient Light Sensor: Description and Operation
The DRL ambient light sensor is a light sensitive variable resistor. The DRL ambient light sensor's resistance decreases as the outside light intensity
increases. Measuring the voltage drop across the DR ambient light sensor and determining whether it should operate in the day mode or in the low light
mode are the 2 basic features of the DRL ambient light sensor.
