Where is the sensor of Toyota VIOS?

The function and position of sensors are different. The position of Toyota VIOS sensor is as follows: 1. Oxygen sensor: installed on the exhaust pipe, it monitors the burnt gas and judges whether the engine is fully burned and whether the mixing degree is too thin or too rich. 2. Wheel speed sensor: generally located on the front wheel brake disc, it mainly collects the speed of the car to judge whether the car slips. If the sensor is damaged, ABS will fail. 3. Water temperature sensor: it is installed next to the temperature controller and converts the temperature of cooling water into an electrical signal. At low temperature, increase the fuel injection or ignition advance angle; At high temperature, prevent explosion and delay the ignition advance angle. 4. Intake pressure sensor: generally installed on the throttle valve, it senses a series of resistance and pressure changes with the engine speed and load, and converts them into voltage signals for ECU to correct fuel injection and ignition timing angle. If the sensor fails, it will cause problems such as ignition difficulty, unstable idle speed and weak acceleration.
