How does the ECM work in a fuel injection system?
Electricity heats up the wire or film, leading to a decrease in current, while air flow cools the wire or film leading an increase in current. The ECM correlates the resulting current flow with air mass, a critical calculation in fuel injection systems.
How does the mass air flow sensor work?
It measures the amount of air that enters the engine via the throttle valve. Mass air flow sensor takes the form of a heated film through which an electric current passes from your car’s Engine Control Module (ECM), which helps to control its temperature.
What is fault code for Mercedes Benz mass air flow?
As confirmation for faulty Mass Air Flow meter is fault code “P0101 – Mass or Air Flow Volume Sensor Circuit Range/Performance”, if it shows this fault it is definitely that MAF has failed. As the P0101 trouble code relates to internal damage, there’s not much that can be done at the roadside to solve the issue.
How does compression work in the air intake system?
Because compression increases the temperature of the intake air, compressed air flows through an intercooler to reduce temperature to reduce the chance of engine ping, detonation, and pre-ignition.
Can a factory MAF sensor handle increased air flow?
However, when air flow is significantly increased, with a larger throttle body and aftermarket intake manifold and cylinder heads, and/or high flow fuel injectors, the factory MAF sensor may not be able to handle the additional flow. Two issues can arise, calibration and size.
