Where is the Buick LaCrosse sensor installed?

Different sensors have different installation positions. The following is the specific installation location of Buick sensor: 1. Oxygen sensor: installed on the exhaust pipe, used to monitor the gas after combustion and judge whether the mixture is too thin or too rich according to the combustion situation. 2. Wheel speed sensor: generally installed on the front wheel brake disc, it mainly collects the vehicle speed to judge whether there are signs of slipping. But ABS is invalid when the sensor is damaged. 3. Water temperature sensor: installed beside the thermostat, it converts the temperature of cooling water into an electrical signal, increases the fuel injection amount or increases the ignition advance angle at low temperature, and prevents combustion and delays the ignition advance angle at high temperature. 4. Intake pressure sensor: generally installed at the edge of the throttle valve, as the name implies, it senses the change of resistance and pressure, and converts it into voltage signal according to different speed loads for ECU to correct fuel injection quantity and ignition timing angle. Failure will cause problems such as difficult ignition, unstable idle speed and weak acceleration. Therefore, the installation position of the sensor will be different with different functions.
