Disconnect mass air flow sensor harness connector. Restart engine and let it idle for at least 5 seconds. Stop engine and reconnect mass air flow sensor harness connector. Make sure DTC P0102 is displayed. WebDec 26, 2024 · The MAF sensor signal is used by the engine control module to calculate the amount of fuel needed for ignition. In winter, the air is denser hence more fuel is injected into the ignition chamber. If the engine gets warmer the gasoline consumption will be less. A mass air flow sensor comes with different numbers of wires.
A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies wi… WebDec 7, 2024 · A MAF sensor monitors the temperature and weight of air entering your engine.
