31432653 Fuel Tank Pressure Sensor

1.  Oxygen sensor: When the oxygen sensor fails, the ECU cannot obtain this information, and it does not know whether the amount of gasoline injected is correct. An improper air-fuel ratio will reduce the engine power and increase emission pollution;

2.  Wheel speed sensor: It mainly collects the speed of the car to determine whether the car has any signs of slipping. Therefore, there is a sensor that collects the wheel speed of the car to complete this work. It is generally installed on the hub of each wheel. Once the sensor is damaged, ABS will fail;

3. Water temperature sensor: When the water temperature sensor fails, the temperature signal of the hot car is often displayed when the cold car is started. The ECU cannot get the correct signal and can only supply the thinner mixture of the engine, so it is not easy to start when the engine is cold. , And it will also be accompanied by unstable idle speed and insufficient acceleration power;

4.  Electronic accelerator pedal position sensor: When the sensor fails, the ECU cannot measure the accelerator position signal, and cannot obtain the correct position of the accelerator pedal. Therefore, the engine will be unable to accelerate or even the engine cannot accelerate;

5.  Intake pressure sensor: As the name implies, the intake pressure sensor senses a series of resistance and pressure changes with different engine speed loads, and converts them into voltage signals for ECU to correct the fuel injection volume and ignition timing angle. Generally installed on the side of the throttle valve, if it fails, it will cause problems such as difficulty in ignition, unstable idling, and weak acceleration.
