A mass air flow (MAF) sensor responds to the amount of air flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the air. The sensor for volume consumption of air is used in many systems for management of engines for measuring value of the transitory cost of air.

Airmass sensor Function troubleshooting | HELLA

+

The airmass sensor is used to measure the intake air mass. It consists of a tubular housing with flow straightener, sensor protection, and sensor module. It is mounted in the intake pipe between the air filter housing and the intake manifold. Two temperaturedependent metal film resistors affixed to a glass membrane are arranged in the air flow.

Video: Diagnosing Replacing a Failing Mass Air Flow (MAF ...
