Some engines do not idle with an air flow meter failure.

Air flow meters may fail or wear out.

An air flow meter also measures the volume of air entering the induction system.

Thus air flow meters are simply an application of mass flow meters for a special medium.

An air flow meter is used in some automobiles to measure the quantity of air going into the internal combustion engine.

Also see Air flow meter.

All modern electronically controlled diesel engines use air flow meter, as it is the only possible means of determining the air intake for them.

Other changes were, different air flow meter, engine ecu, cam angle sensor and throttle position sensor.

In its simplest electronic form, the instrument consists of an air bottle connected to the external atmosphere through a sensitive air flow meter.

If the engine is naturally aspirated, an air temperature sensor is located in the air flow meter to work out the air mass.

The engine employs an electronic fuel injection system using a vane-type air flow meter and an electronic ignition system with a crankshaft angle sensor instead of a distributor.

The system is closed loop using camshaft sensors, crankshaft sensors, air flow meter, throttle position as well as oxygen sensors and/or Air-Fuel ratio sensors in order to calculate engine load.

In the development process of internal combustion engines with engine test stands, an air flow meter/air flow measuring unit is used for measuring the continuous gravimetric air consumption of combustion engines.

The Turbo A models also measured air based on manifold pressure rather than using an air flow meter, had a larger intercooler, larger throttle body, optimized CT-26 turbo, and various other differences.

The industrial division's products include gas mass flow meters, air flow meters, biogas flow meters, thermal mass flow meters, gas flow switches, liquid flow switches, flow sensors, level switches, and flow conditioners.

The vane (flap) type air flow meters (Bosch L-Jetronic and early Motronic EFI systems or Hitachi) actually measure air volume, whereas the later "hot wire" and "hot film" air mass meters measure speed of air flow.

In many cars (with the exception of some turbocharged models), inputs from the air flow meter are also ignored, as they might otherwise lower engine performance due to the mixture being too rich or too lean, and increase the risk of engine damage due to detonation if the mixture is too lean.

The design of the 13CU also deviated from the original L-Jetronic design in that it used a hot-wire air mass sensor rather than the Jetronic's mechanical flap sensor.
