The air flow meter continuously measures the airflow drawn in by the engine. This allows the car's computer to constantly adjust the fuel injection parameters.
Proper operation of the air flow meter allows the air/fuel mixture to be optimized, ensuring constant performance in all circumstances and minimal consumption.

Air Flow Meter Location
The air mass meter is located between the throttle body and the air filter. Its installation is quite simple and does not require any special knowledge of automotive mechanics.
Causes of a flow meter out of service
Air impurities very often accumulate on the sensitive part of the sensor and disrupt its operation. Your vehicle's computer thus receives incorrect information.
Symptoms of a faulty flow meter
- Unstable idle
- Increased fuel consumption
- Loss of power observed
- Jolts
- Smoke released (in some cases)
