It Is A Sensor That Detect Light So If Its Dark Your Screen Monitor Brightness Will dim down so you're not looking at one source of extreme bright light, When Its Bright The Screen Monitor Will go up to compensate for the extra light around you so you can still see the monitor comfortably
how do you replace ambient light sensor on 2002 silverado
I believe it is the Ambient light sensor to auto adjust screen brightness.
In my 2004 GMC Canyon, the ambient light sensor is mounted at the right side of the dashboard. It is mounted below the dashboard and has a lens on the surface so that it can measure the ambient light that reaches the sensor through the windshield.
To measure ambient temperature, you can use a thermometer or a temperature sensor placed in the area you want to monitor. It's important to place the sensor away from direct sunlight or sources of heat to get an accurate reading. Ambient temperature is the surrounding temperature of a specific environment.
Not wanting to state the obvious here, but it's a sensor that detects the ambient (outside) temperature. This then links through to a light on the dash and is used to warn you of a possible risk of ice. HTH
The ambient air temperature sensor is in front of the radiator. Connecting wires come from the right, near the rear of the left head light, as you are facing the engine from the front of the car.
The airflow ambient temperature sensor is located on the air intake housing. The sensor should be labeled as the airflow ambient temperature sensor.
Most vehicles use a light sensor to detect the ambient light level and automatically turn on the daytime running lamps when it gets dark. This sensor is usually located on the dashboard or near the rearview mirror.
I posted pictures on the location and replacement of an ambient temp. sensor for a 2001 S40. Google "ambient temperature sensor location/replacement" or go to Matthew's Volvo site and search there.
middle of the dash, up by the windshield. looks like a little black LED light, but obviously doesn't light up.
The iPod touch has an Ambient Light Sensor at the top of the device that detects how much ambient light the environment has and adjusts the brightness of the device accordingly to make things more viewable in different lighting conditions.
