What to do if your air flow sensor is dirty?

If a sensor is dirty, your mechanic may suggest cleaning it (cleaning the airflow sensor is a delicate procedure) as a temporary solution; sometimes it could help. When replacing the mass air flow sensor, make sure the air filter is installed properly.

What kind of meter is used to test airflow?

With a probe on a cord, these meters access hard-to-reach places in duct. This meter is often used to test airflow through supply and return grilles and air filters.

How is the mass air flow sensor tested?

How the mass air flow sensor is tested. In modern cars, the only way to test the mass air flow sensor is with a scan tool. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. They compare the readings to the specifications or to the readings of a known-good mass airflow sensor.

What’s the accuracy of an inline flow meter?

Measure the total flow volume of gasoline, diesel fuel, and kerosene. More than twice as accurate as standard totalizers for fuel, these are rated for ±2% accuracy. Often used in heating, cooking, and power-generating systems. Designed for use with light oils.
