How To Save Gas While Driving: 23 Hacks! The Ultimate Guideĥ Wire Mass Air Flow Sensor Wiring Diagram 5 Wire Mass Air Flow Sensor Wiring DiagramĪ five-wire MAF sensor consists of five wires.Ī MAF sensor power wire gives a positive current to the MAF sensor.

Accurate Measurements: The MAF Sensor measures the mass flow rate of air entering a fuel-injected internal combustion engine, allowing for accurate fuel calculations and delivery to the engine. This helps control humidity, as the ECU adjusts fuel injection to account for humid air being less dense than dry air.ĥ. Humidity Control: The MAF Sensor has a platinum wire passing through the intake path of the engine and sends information to the ECU. Hot Wire MAF Sensor Benefits: The Hot Wire MAF Sensor is less sensitive to location and orientation and responds faster to changes in air flow rate.Ĥ. This helps improve fuel efficiency as the ECU adjusts fuel injection accordingly.ģ. Fuel Efficiency: The Mass Air Flow (MAF) Sensor monitors air levels and sends this data to your car’s electronic control unit (ECU). Improved Engine Performance: The Mass Air Flow (MAF) Sensor allows for a correct air/fuel ratio within the engine’s combustion chamber, resulting in improved engine performance.Ģ.
