Service Interval- Initial cleaning: 5,000 km, Clean or change every 10,000 km as
required. However, change every 30,000 km.
- If the vehicle is operated under severe condition (short distance
driving, extensive ldling or driving in dusty condition): More frequent
maintenance is required.

OVERVIEW AND OPERATION PROCESS
1. INTAKE SYSTEM LAYOUT
1) Work Flow of Intake System
HFM Sensor
The HFM sensor is installed in the air intake
passage between the air cleaner and the intake
manifold. It measures the air volume supplied to
the combustion chamber and the ai
r
temperature.
Major Functions
It controls the EGR feedback.
It controls the pressure control valve for the
turbocharger booster. -

EGR Valve and Its Location
(* For details, refer to "EGR" section.)
Vacuum Modulator
Turbocharger Intercooler
The charging efficiency may be lowered or the
knocking may happen as the intake air is
heated and the density of air is lowered. The
intercooler is the device which cools the
supercharged air.

(2) Turbocharger Intercooler Assembly
The turbocharger is designed to improve the engine power by introducing more air (oxygen)
into the engine.
However, the intake air is heated during the compression process in the turbocharge
r
compressor and the density is lowered.
The intercooler is the device which cools (50 ~
the air entering the engine from
high temperature (100 ~
to maintain the turbocharging efficiency.
Thus, more air is entered the cylinder than the engine only with the turbocharger to give more
power.
Intercooler
For removal and installation procedures, refer to the "Cooling system" section in DI engine
service manual. -
