What is a Jetta sensor?

The positions of Jetta's main sensors are as follows: 1. Oxygen sensor: The oxygen sensor is installed on the exhaust pipe to monitor the gas after combustion. It can be judged whether the engine is fully burned and whether the mixing degree is too lean or too rich. 2. Wheel speed sensor: it is mainly used to collect the rotating speed of the car to judge whether the car is slipping. Sensors are usually 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 next to the thermostat and converts the temperature of cooling water into an electrical signal. At low temperature, the fuel injection or ignition advance angle can be increased; At high temperature, it can prevent explosion and delay the ignition advance angle. 4. Intake pressure sensor: generally installed on the throttle. The intake pressure sensor can sense a series of resistance and pressure changes and convert them into voltage signals of different engine speeds and loads for ECU to correct the fuel injection and ignition timing angles. In addition, Jetta is equipped with other sensors, such as camshaft position sensor. These key sensors can help Jetta achieve efficient fuel injection and time control.
