MASS AIR FLOW SENSOR
(MAFS)

FUNCTION AND OPERATION PRINCIPLE

MAFS uses a hot-film type sensing element to measure
the mass of intake air entering the engine, and send the
signal to ECM.
A large amount of intake air represents acceleration or
high load conditions while a small amount of intake air rep-
resents deceleration or idle.
The ECM uses this information to control the EGR sole-
noid valve and correct the fuel amount.

Fig.2

Fig.1) AFS signal waveform at IG KEY "ON". It shows digital signal of 50% duty, 1.8KHz.  
Fig.2) AFS signal waveform at idle(790RPM, EGR actuator duty 5%, air flow for each cylinder 410mg/st). 
          It shows digital signal of 50% duty, 2.2~2.7KHz.

COMPONENT INSPECTION

1.

Check the MAFS visually.
-

Mounting direction correct.

-

Any contamination, corrosion or damage on con-
nector.

-

Air cleaner’s clogging or wet.

-

MAFS cylinder’s deforming or blocking by any for-
eign material.

2.

Check any leakage on intake system and intercooler
system.
