Hello friends welcome to my YouTube channel
Friends Aaj ke is video me bataya gaya hai ki Maruti Suzuki Swift Dzire me Check Engine Light problem kaise diagnose karte hai. Aaj ke is video me bataya gaya hai ki agar car me low pickup problem ho to aapko kya replace karna hota hai . Swift Dzire me Mass Air Flow Sensor Replacement Kaise karte hai. Mass Air flow sensor ka location kaha aata hai. Mass Air flow sensor ko kaise Diagnose karte hai or Mass Air flow Sensor ko clean kaise karte hai. Mass Air flow sensor kharab hone par car me kya fault aa sakta hai. Aap sab fault ko kaise clear kar sakte hai. 

More Information about Mass Air flow sensor
A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine.

The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder.

There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air.

Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0.0–5.0 volt or a pulse-width modulation (PWM) signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings for most post on-board diagnostics (OBDII) vehicles. Vehicles prior to 1996 could have MAF without an IAT. An example is the 1994 Infiniti Q45.

When a MAF sensor is used in conjunction with an oxygen sensor, the engine's air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop controller predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass. Also see the manifold absolute pressure sensor (MAP sensor). Since around 2012, some MAF sensors include a humidity sensor.
