The intake pressure sensor is generally installed between the air cleaner and the throttle?

1, oxygen sensor: When the oxygen sensor fails, the ECU can't get this information, so it doesn't know whether the injected gasoline quantity is correct. An inappropriate air-fuel ratio will reduce the engine power and increase the emission pollution;

2. Wheel speed sensor: it mainly collects the rotating speed of the car to judge whether there are signs of slipping. Therefore, there are special sensors to collect the wheel speed of the car to complete this work, which are 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, it often displays the temperature signal when the cold car starts, and the ECU can't get the correct signal, so it can only supply lean mixture to the engine, which makes it difficult to start the cold car, and it will also be accompanied by problems such as unstable idle speed and insufficient acceleration power.

4. Electronic accelerator pedal position sensor: When the sensor fails, the ECU can't measure the accelerator position signal, and the correct position of the accelerator pedal can't be obtained, so the engine can't accelerate, or even 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 fuel injection quantity and ignition timing angle. Generally installed on the throttle side, if it fails, it will cause problems such as ignition difficulty, unstable idle speed and weak acceleration.
