What are the causes of intake pressure sensor failure?

[SanPaul]

The causes of intake pressure sensor failure are as follows: 1. Open or short circuit in the internal wiring of the sensor. 2. The output signal of the sensor cannot change with the variation of intake manifold vacuum. 3. The output signal voltage of the sensor is too large or too small, deviating from the normal range. Below is information about the function of the intake pressure sensor: The function of the intake pressure sensor is to detect the absolute pressure in the intake manifold behind the throttle. It detects changes in the absolute pressure within the manifold based on engine speed and load, then converts this into a signal voltage sent to the ECU. The ECU controls the basic fuel injection quantity based on the magnitude of this signal voltage.
