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.

Description
The automatic transmission is a combination of 3 - element 2 - phase 1 - stage torque converter and double shaft
electrocally - controlled unit which provides 4 speeds forward and 1 reverse. To improve the efficiency of power
transmission, the line pressure control was changed applying “Variable Force Solenoid (VFS) valve” on this model.
However, adopting VFS on this model, the line pressure is variably changed according to TPS and the vehicle speed,
this will enable more improved efficiency of power transmission and fuel consumption.
Characteristics
Some of the characteristics include:
▶Different power transfer
▶Different component layout
▶New shift logic(HIVEC) to improve shift feeling
▶Position of Valve Body
▶Variable shift pattern
▶Communication protocol and method
▶Step gate type shift lever.
Item Details
Weight Reduction 1. Aluminum oil pump
a. 2.3kg Approx
2. Pressed parts a. Retainer and hub of brakes and clutches
b. Carrier of planetary gear set
Better shift quality 1. Independent control of clutches and brakes enabled better control of
hydraulic pressure and skiped shifts (4 to 2, 3 to 1)
2. During N to D or N to R shift, feedback control adopted.
3. When starting from Creep condition, reduction of shock.(Creep condition is
controlled with 1st gear)
4. Solenoid valve frequency is increased for more accurate control. 35Hz to
61.3Hz except DCCSV that is 35Hz and VFS that is 600Hz.
5. HIVEC adoption for better shift feeling.
6. Variable shift pattern.
Increase in Power train efficiency 1. Fully Variable Line Pressure
2. VFS(Variable Force Solenoid)
- Manual shifting possible
- Step gate type shift lever
