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.
The engine requires the same mass of fuel in both conditions because the mass of air entering the cylinders is the same. If the throttle is opened all the way in condition 2, the manifold absolute pressure will increase from 50 kPa to nearly 100 kPa (14.5 psi, 29.53 inHG), about equal to the local barometer, which in condition 2 is sea level.
The 2004–2011 CVPI is rated for 186.5 kW (254 PS; 250 hp) @4,900 RPM. This better-flowing air intake system also has an integrated 80 mm (3.1 in) mass airflow (MAF) sensor that is part of the airbox lid (but can be serviced individually). This allows for much more precise flow calibration and reduces the chances of air leakage.
To manufacture a check-engine light, we unplugged the mass-airflow sensor on the Corolla, started the car, and verified that the light was on. Then we plugged in each scanner and evaluated the ...

Alternatively, a manifold vacuum sensor can be used. The manifold vacuum sensor signal, the throttle position, and the crankshaft speed can then be used by the engine control unit to calculate the correct amount of fuel. In modern engines, a combination of all these systems is used. [5] Mechanical injection controlling systems as well as ...
