How Mass Air Flow (MAF) Sensor Works in Hindi

A Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. The mass air flow sensor measures the amount of air entering the engine or the air flow.
In modern cars, an intake air temperature or IAT sensor is built in the mass air flow sensor. There are few types of air flow sensors, however, modern cars use a hot-wire type.

A hot-wire mass air flow sensor has a small electrically heated wire (hot wire). A temperature sensor installed close to the hot wire measures the temperature of the air near the hot wire.
When the engine is idling, a small amount of air flows around the hot wire, so it takes a very low electric current to keep the wire hot. When you press the gas, the throttle opens allowing more air to flow over the hot wire. The passing air cools the wire down.
The more air flows over the wire, the more electrical current is needed to keep it hot. The electric current is proportional to the amount of air flow. A small electronic chip installed inside the air flow sensor translates the electric current into a digital signal and sends it to the engine computer (PCM). The PCM uses the air flow signal to calculate how much fuel to inject. The goal is to keep the air/fuel ratio at the optimal level.
In addition, the PCM uses the air flow readings to determine the shift points of the automatic transmission. If the air flow sensor doesn't work properly, the automatic transmission might shift differently too.

Bahut hi achi jaankari

[@AsimAli-sc7dj]

Sir you are doing great job👍.
I have a question"what is differnce between MAF and MAP sensnor"
Why some have MAF and other have MAP?
Thank you ❤

Yes

sir sensor ko petrol se dho sakte he

[@lorryboysajju]

Sir mera maf sensor 3 baar change kiya
Fir kharab ho gaya
Mechanic ne ab us ko disconnect kar ke bola ki aise he chalao kuch nhi hoga
Pickup to sahi hai abhi but badme me koi problem hoga kya?
Pls reply sir

Hello sir .
Optra 1.6 petrol 2005
Hai meri car mai abhi 2month say starting achi hoti per 2000rpm k baad rpm vary kerta hai 800 1000 500 aprox fir off ho jaati hai.
Dobera start kerne per normal rpm rehta hai 900rpm.
Maine petrol,Airfilter dono change kia hai or throtal b clean kia per problem ni theek hui.
I request to you please suggest what I do?

Dear
Mass air sensor air flow ko measure karta hai. Based on air flow fuel is injected.

[@RizwanKhan-is1tn]

Sir but diesel engine me throttle to nhi hota. Phir acceleration ke doran kitni air chahiye wo kam Jada q nhi hoti
