[Working principle]The outside air into the throttle flow through the sensor, into the engine take away a very large part of the heat, the greater the flow of outside air, take away more heat in order to maintain the necessary temperature of the air flow sensor, it needs additional current to heat the sensor, it regulate the size of the air flow through the current. [Replace in Time]When your car shakily, acceleration is weak, fuel consumption increases, black smoke from the exhaust pipe, etc indicating that your mass air flow sensor needs to be replaced. Replacing the sensor improve fuel efficiency, assist the catalytic converter in better eliminating harmful gases from the vehicle's exhaust system, reduce emissions, and prevent premature catalytic converter damage. [NOTE]Please clean out the air box and replace the air filter before installating this Mass Air Flow Sensor Meter, or the Code and Check Engine Light may keep showing even if you replace a Mass Air Flow Meter Sensor measures the volume and density of air entering the engine, providing highly accurate airflow readings to the ECU over a wide range of ambient temperatures.
