Mass Air Flow Sensor(MAFS)

2007 > 2.7L V6 GASOLINE >
INSPECTION
FUNCTION AND OPERATION PRINCIPLE
Mass Air Flow Sensor (MAFS) is a hot - film type sensor and is located in between the air cleaner and the throttle
body. It consists of a tube, a sensor assembly and honeycomb cell and detects intake air quantity flowing into the
intake manifold. Air flows from the air cleaner assembly through the honeycomb cell and over the hot film element. At
this time, heat transfer is generated by convection and this sensor loses its energy. This sensor detects the mass air
flow by using the energy loss and transfers the information to the PCM by frequency. The PCM calculates fuel quantity
and ignition timing.

Manifold Absolute Pressure Sensor (MAPS)

2007 > 2.7L V6 GASOLINE >
INSPECTION
FUNCTION AND OPERATION PRICIPLE
Manifold Absolute Pressure Sensor (MAPS) is speed- density type sensor and is installed on the surge tank. This
MAPS senses absolute pressure in surge tank and transfers this analog signal proportional to the pressure to the
PCM. The PCM calculates the intake air quantity and engine speed based on this signal. This MAPS consists of
piezo - electric element and hybrid IC that amplifies the element output signal. The element is silicon diaphragm type
and adapts pressure sensitive variable resistor effect of semi- conductor. 100% vacuum and the manifold pressure
applies to both sides of it respectively. That is, this sensor outputs the silicon variation proportional to pressure change
by voltage.

Intake Air Temperature Sensor(IATS)

2007 > 2.7L V6 GASOLINE >
INSPECTION
FUNCTION AND OPERATION PRICIPLE
Intake Air Temperature Sensor (IATS) is installed inside the Mass Air Flow Sensor (MAFS) and detects the intake air
temperature. To calculate precise air quantity, correction of the air temperature is needed because air density varies
according to the temperature. So the PCM uses not only MAFS signal but also IATS signal. This sensor has a
Negative Temperature Coefficient (NTC) and its resistance is in inverse proportion to the temperature.
