Natural gas J6 shows the position of the intake air flow sensor.

The intake flow sensor is generally installed on the intake pipe of the engine, behind the filter element of the air cleaner and in front of the throttle body.

I.e. between the air filter element and the throttle valve. The following is more information about the intake air flow sensor: 1. Intake air flow sensor is a technical term of automobile, also known as "air flow sensor" and "air flow meter". 2. The air flow sensor is an instrument that converts the inhaled air flow into an electrical signal. It is a sensor used to measure the air intake in the automobile air intake system. 3. The air flow sensor on the car mainly detects the air intake of the engine, and then converts the information of the air intake of the engine into an electrical signal and sends it to the ECU. Then the driving computer will calculate the fuel injection quantity according to the information. 4. The air intake system consists of air filter element, air flow sensor, air intake pressure sensor, throttle body, idle speed control valve, power room, air intake manifold, etc. The automobile air intake system has two main functions. First, reduce noise and improve ride comfort. The other is to deliver clean, dry, sufficient and stable air for the engine, so as to avoid the abnormal wear and tear of the engine caused by impurities and large particle dust in the air entering the engine combustion chamber.
