[Working principle]The outside air into the throttle will flow through the sensor, into the engine will 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 will regulate the size of the air flow through the current.[Replace in Time]When your car idles 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 MAF sensor will 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 new MAF Mass Air Flow Meter MAF 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.Condition: NewItem Type: Mass Air Flow SensorManufacturer Part Number: AFH70M-101,22752508 ,4819491Other Part Number: 22752508 ,4819491Interchange Part Number: AFH70M101,4819491Fitment Type: Direct ReplacementNumber of Pin: 5PinsFit for:FOR CHEVROLET CAPTIVA (C100, C140) 2.2 D 4WD 03/2011 - 2231 135 184 A 22 DMH SUVFOR OPEL ANTARA 2.2 CDTi 12/2010 - 2231 120 163 A 22 DM A 22 DM SUVFOR OPEL ANTARA 2.2 CDTi 4x4 12/2010 - 2231 135 184 A 22 DMH A 22 DMH SUVFOR OPEL ANTARA 2.2 CDTi 4x4 12/2010 - 2231 120 163 A 22 DM A 22 DM SUVFOR VAUXHALL ANTARA (J26, H26) 2.2 CDTi 12/2010 - 2231 135 184 A 22 DMH SUVcolor:BlackMaterial:plasticPackage Contents:1 x MAF SensorOnly the ad
