• FUNCTION - It can effectively solve the problem of Acceleration difference, Idling instability and Exhaust pipe smoke for your car. Let you drive easily and joyfully.Before purchasing this part, check the compatibility information or call your local dealer to verify the correct OEM part number and clean out the air box and replace the air filter before installing the MAF Meter, or the Code and Check Engine Light may keep showing even if you replace a new MAF
• Tips to one - If it works well at first but months later can not work,Please clean the inside of the duct and the air filter; If the Engine code with P0100 or P0101,please check the air flow meter plug for any contact failure and measure it with a multimeter;
• Tips to two - When the Engine code with P0102, maybe the air duct in the car is too dirty,and dust enters the sensor head, which weakens the signal strength; If everthing is alright but the car is not stable at idle speed, and the throttle is weak when driving at low speed, please check the valve and estimate the leak. It must be sealed.
