9/9/2020· The engine associated sensors include the TP (Throttle Position) sensor, ECT (Engine Coolant Temperature) sensor, MAP (Manifold Absolute Pressure) sensor, and MAF (Mass Air Flow) sensor. Transmission related sensors include the TFT (Transmission Fluid Temperature) sensor, TSS (Turbine Shaft Speed) sensor, also called an input shaft speed sensor ...

Mass flow sensor Wikipedia

+

A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuelinjected 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 with …

Bad Mass Air Flow Sensor? (7 Symptoms with Fixes) | The ...

22/10/2018· To clean the sensor surface, you should only use a Mass Air Flow Sensor cleaner (MAF cleaner) or electrical contact cleaner. Try not to touch the sensor surface with your hands as grease and dirt from your hands can damage it. Let the sensor surface dry completely before refitting it to the vehicle. 4. Refit the mass air flow sensor to the car.

Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.

MAF Mass Air Flow Sensor: Symptoms Cleaning Dirty MAF

+

The MAF sensor provides the ECM and TCM with valuable information regarding engine load. It is calculated by multiplying air density by air volume. The transmission control unit uses this information for shift control. A mass air flow sensor left unplugged, faulty, or dirty will dramatically affect a …

22/6/2020· The mass air flow (MAF) sensor is an important component which the engine control unit depends on. When the flow of air enters the fuel injection system of the engine, the mass air flow sensor will analyze how much air is flowing in there. It will then relay this information back to the engine control unit.
