Description

Air intake pressure sensor (ManifoldAbsolutePressureSensor), hereinafter referred to as a MAP. It is connected to the intake manifold with a vacuum tube, and with the different speed load of the engine, the vacuum change in the intake manifold is induced, and then the resistance change in the sensor is converted into a voltage signal for the ECU to correct the injection amount and ignition timing Angle.

In the EFI engine, the intake pressure sensor is used to detect the intake volume, which is called the D-injection system (velocity density type). The intake pressure sensor detects the intake volume is not directly detected like the intake flow sensor, but uses indirect detection, and it is also affected by many factors, so there are many different places in the detection and maintenance than the intake flow sensor, and the fault generated also has its particularity.
