16 where is the Buick lacrosse light sensor?

The light sensor of Buick LaCrosse is on the center console.

The ball protruding from the Buick center console is a light sensor, which is the basis of screen brightness and automatic air conditioning adjustment.

The location of the lacrosse sensor is as follows: 1. Oxygen sensor: The oxygen sensor is installed on the exhaust pipe, which monitors the combusted gas and judges whether the engine is fully burned or not, and the mixture is too thin or too rich. 2. Wheel speed sensor: The wheel speed sensor is usually located in the front wheel brake disc, and mainly collects the vehicle speed to judge whether there are signs of slipping. So there is a special sensor to collect the wheel speed of the car to complete this work, which is generally installed on the hub of each wheel. Once the sensor is damaged, abs will fail. 3. Water temperature sensor: The water temperature sensor is installed beside the thermostat to convert the temperature of cooling water into an electrical signal, increase the fuel injection amount or ignition advance angle at low temperature, prevent explosion at high temperature and delay the ignition advance angle. 4. Intake pressure sensor: generally installed at the throttle. As the name implies, the intake pressure sensor senses a series of resistance and pressure changes when the engine speed and load are different, and converts them into voltage signals for ecu to correct the fuel injection quantity and ignition timing angle. If something goes wrong, it will cause problems such as difficult ignition, unstable idle speed and weak acceleration.
