Yes. The 13 new Jetta models have a throttle sensor, and the Volkswagen Jetta has three sensors. The locations are as follows.
1. Oxygen sensor: Installed on the exhaust pipe, it is used to monitor the burned gas and determine whether the engine combustion is sufficient and whether the mixing level is too lean or too rich.
2. Wheel speed sensor: In the front wheel brake disc, it mainly collects the speed of the car to determine whether the car is slipping.
3. Water temperature sensor: Generally installed next to the thermostat, it converts the temperature of the cooling water into an electrical signal and increases the amount of injection when the temperature is low.
4. Intake pressure sensor: generally installed on the throttle valve. As the name suggests, the intake pressure sensor senses a series of resistance and pressure changes as the engine speed and load vary, and converts it into a voltage signal for the ECU to correct the fuel injection amount and ignition timing angle. If it fails, it will cause problems such as difficulty in ignition, unstable idling, and weak acceleration.
