· We have sensors that communicate engine parameters, like coolant temperature, engine RPM, Oxygen in the exhaust, throttle position, engine speed by crankshaft rotation, and engine load via a MAP (manifold absolute pressure) or amount of airflow entering the engine MAF (Mass AIr flow sensor). MAF sensors have three different types starting with the vane air flow, the hot wire MAF and a …

MAF sensor which measures the mass of air flow – Hot Film sensor (HFM) Fig. 4. Hotfilm MAF sensors function much like a hot wire sensor, and used a centrallyheated film or metallic gridtype element. One side of the film encounters cooling airflow, while the shielded backside maintains a consistent temperature, and the current differential between the two is measured and relayed as a ...

MAF Sensor Testing The TechAssist Team It’s always a good idea to test a Mass Airflow (MAF) sensor before replacing it. Here is a fast and accurate way to track a MAF’s performance and output to the PCM. Connect a scan tool to see the MAF sensor Parameter Identification Data (PID) information. With the engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g ...
To do this, hot film mass air flow sensors measure a small portion of the air entering the engine. The sensor takes into account positive and negative intake pulses caused by intake and exhaust valves opening and closing. Intake air temperature or ambient pressure changes have no effect on air mass measurement. HFM5 sensor housing and measuring tube are designed to accommodate engine …

· A mass airflow sensor (MAS) determines the mass of air entering a vehicle''s fuel injection engine, and passes that data to the Engine Control Unit, or ECU. The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine. When a vehicle''s mass airflow sensor is faulty or defective it can cause a variety of problems, and usually results ...

· Take off air intake guard. Step 2. Undo bolt connecting the MAF sensor to the Air intake to the engine. Disconect MAF wires. Step 3. Undo Air box cover, 3 screws. Put a rag in the pipe coming out of the engine to stop crap getting into the engine. Replace Air filter and clean bugs out of the bottom of the air box. Step 4.
MASS AIR FLOW SENSOR INVESTIGATION. No dealership or service provider, when contacted, has ever been able to provide us with evidence to support this "myth," and in fact, our investigations have revealed that even authorized dealerships are simply speculating and do not have the test equipment necessary to know whether the sensor has failed or why.
Splash water, such as during heavy rain, can enter the clean air side via the air filter and damage or contaminate the sensor. Salt water, such as from road salt and slush, increases this effect. Oil particles from oilwetted sports air filters can damage or contaminate the sensor. Oil mist on hotfilm sensor.

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 the ambient ...
· Most modern EFI engines have a Mass Air Flow (MAF) sensor located in the air intake of the engine. This is the device that measures how much air is coming into the engine so that the computer can determine how much fuel it needs to inject. While the MAF sensor does not directly measure the actual flow rate of air, it measures the density. Air density changes with temperature, altitude and ...
Mass Air Flow Sensors ( MAF Sensors) are precision components that measure the amount of airflow entering the intake manifold and must communicate clearly with the Engine Control Module (ECM). Remanufactured MAF sensors with debris from prior use can hinder this communication and cause the vehicle to experience drivability issues.
· On the newer type of MAF sensor, both hot wires are inside the air inlet cavity but within view and these too can be easily cleaned by just spraying them. 3. If the MAF sensor is dirty, both resistors on the hot wires will be full of dark fuzz. A clean resistor is usually a light gray color, and of course, it won''t have any type of fuzz on it. 4. Resist the temptation to physically wipe the ...

· The mass air flow (MAF) sensor in an automobile converts the amount of air drawn into the engine into a voltage signal to calculate engine load. This is necessary to determine how much fuel to inject, when to ignite the cylinder, and when to shift the transmission. The air flow sensor is located directly in the intake air stream, between the air cleaner and throttle body where it can measure ...
