Where is the Jetta sensor?

The main sensor positions of Jetta are as follows: 1. Oxygen sensor: an oxygen sensor installed on the exhaust pipe, which is used to monitor the burnt gas and judge whether the engine combustion is fully mixed or too rich; 2, wheel speed sensor: mainly to collect the speed of the car to judge whether there are signs of slipping, so there are sensors specially collecting the wheel speed of the car to complete this work, 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 next to the thermostat and converts the cooling water temperature into an electrical signal. When the temperature is low, the fuel injection amount increases or the ignition advance angle increases. When the temperature is high, the explosion-proof ignition delays the ignition advance angle. 4. Intake pressure sensor: Generally, the intake pressure sensor installed on the throttle, as its name implies, senses a series of resistance and pressure changes with the different engine speed and load, and converts them into voltage signals for ECU to correct the fuel injection amount and ignition timing angle.
