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.
