What is the MAP sensor?

MAP is the intake pressure sensor. The intake pressure sensor detects the absolute pressure of the intake manifold behind the throttle. It detects the change of the absolute pressure in the manifold according to the engine speed and the load, and then converts it into a signal voltage and sends it to the signal voltage. An electronic controller (ECU) that controls the amount of basic fuel injection based on the magnitude of this signal voltage. Poor operation of this sensor can cause the vehicle to be difficult to start, the sensor cannot be repaired, and only a new replacement can be replaced after the failure.

The sensor (English name: transducer/sensor) is a detection device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information. Requirements for transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first step in achieving automatic detection and automatic control. The existence and development of the sensor allows the object to have senses such as touch, taste and smell, and let the object slowly become alive. Generally, it is divided into ten categories according to its basic sensing function: thermal element, photosensitive element, gas sensor, force sensor, magnetosensitive sensor, humidity sensor, sound sensor, radiation sensor, color sensor and taste sensor. .
