What does MAF mean in automotive systems?

In automobiles, MAF is the air flow meter of the engine intake system. The control of fuel injection pulse width by air flow sensor is divided into three parts: the air flow sensor (MAF), throttle position sensor (TPS), and engine speed sensor control the basic fuel injection pulse width; The intake temperature sensor (MAT), coolant temperature sensor (ECT), and atmospheric pressure sensor (BARO) are responsible for adjusting the fuel injection pulse width. No fault code is set for air flow rate; If the throttle position sensor of the vehicle is damaged, and the throttle opening data transmitted to the ECU is 3% without any change in engine operating conditions, the input information to the ECU is actually the engine speed of 800r/min, throttle opening of 3%, and air flow (MAF) sensor of 2kHz, while the engine speed is 800r/min. Section 1: Engine Coolant Temperature (ECT) Sensor and Its Maintenance Section 2: Intake Air Temperature (IAT) Sensor and Its Maintenance Section 3: Absolute Pressure (MAP) Sensor and Its Maintenance Section 4: Mass Air Flow (MAF) Sensor and Basic Maintenance Section 7: Crankshaft Position (CKP) Sensor and Its Maintenance Air Flow (Hz) Air Flow (MAF) Sensor The signal input to the powertrain control module is a frequency signal that varies from 3000 Hz at idle to 7000 Hz at Wide Open Throttle (WOT) The power system control module converts the frequency signal into grams per second for displaying air flow on the fault diagnosis instrument. Coolant, also known as antifreeze, antifreeze, water tank treasure, etc. The main function is to protect the normal and good operation of the engine, circulate in the engine water tank, and achieve anti freez

ing, anti boiling, anti rust, anti-corrosion and other effects. Most antifreeze liquids are red or green in color to observe whether there is leakage or to distinguish them from other engine fluids and avoid confusion. The throttle position sensor, also known as the throttle opening sensor or throttle switch, is a device used to detect the engine status. The LC-QA1 atmospheric pressure sensor adopts Swiss imported chips for packaging, and after precise temperature compensation, it has the characteristics of high precision and high sensitivity. The measurement of air pressure and altitude using Mu Si Xin is a complementary product of automatic weather stations.
