WebFeb 28, 2024 · The principles of how the sensor works haven’t changed. The 8-pin sensor is typically a hot-wire design. As with many other MAF sensors, the ECM monitors the current flow through the sensor to determine how much air is flowing into the engine. What has changed is the addition of the humidity sensor, BARO sensor, and an additional … WebThere are two common types of MAF sensors: hot-wire and hot-film. Hot-wire types are the most common; troubleshooting procedures for hot …
WebDec 26, 2024 · Hot Wire MAF Sensor Benefits: The Hot Wire (MAF Sensor) is less sensitive to location and orientation and it senses faster changes in air flow rate. 4. Humidity … WebWhile there are several distinct MAF sensor technologies ranging from hot-wire or hot-film to Karman vortex and Corialis sensors, and while MAF sensor outputs may take the form of variable frequency, variable current or a simple analog voltage, the diagnostic principles remain largely the same.
WebAug 30, 2024 · Testing for malfunctioning or sensor failure can be performed by testing the resistivity of the reference and exposed wires for hot-wire sensors. A shorted sensor or a snapped wire should read infinite resistance and signifies the critical issue of mass airflow sensor failure. Another method is to connect the sensor to an oscilloscope and, for ... WebFeb 10, 2024 · Hot Wire-Type Mass Air Flow Sensor – This is commonly found on most modern cars.
