Swirl control valve
It operates variably in accordance with the
engine load and rpm.
Refer to Chapter “Engine Control”.
Intake manifold
It is the passage for intake air when the swirl
vale is operating. The T-MAP sensor for
measuring the pressure and temperature of
pressurized air in turbocharger is installed on
the left top of intake manifold.
3. LAYOUT OF INTAKE SYSTEM
1) Overview
The intake system for D20DTF(Low CO2) engine is equipped with a throttle body which includes a flap.
This flap is controlled by an electrical signal to cut off the intake air entering to the engine when the
ignition switch is turned off. The intake manifold contains the swirl control valve and dual port system to
make the optimum turbulence. The T-MAP sensor is located on the left top of the intake manifold and
the HFM sensor for precise control is located at the rear side of air cleaner. To reduce the intake noise
and to improve the intake efficiency, the volume of air cleaner has been increased.
2) Components
Electric throttle body

HFM sensor, version 6
Refer to Chapter “Engine Control”.
Air cleaner assembly
Its volume is increased and air flowing
efficiency is improved.Intercooler assembly
Its volume is increased and cooling efficiency is
improved.

3. BASIC INSPECTION
1) Battery Terminal
Make sure the terminal connections are
securely tightened. If the terminals are
corroded, clean them or replace the battery. -
* Cleaning
Remove the corrosion or dirt with a wire brush
or sand paper, and then wash out with
lukewarm soapy water.
2) Measuring the Voltage Drop
Measuring at battery terminal ▶
Measure the voltage between battery
terminal (+. -) and wiring clamp. -
Specified valuebelow 0.3V
If the terminals are corroded, clean and
retightening them. If the specified tightening
torque cannot be kept, replace the clamp.
Terminal (+)
Terminal (-)
Terminal (+): 4 ~ 5 Nm
Terminal (-): 6 ± 1Nm

14-6
Measuring at (-) wiring ▶
Measure the voltage between battery wiring
and body ground. -
Specified valuebelow 0.3V
If the voltage is out of the specified value,
check the wiring mounting bolt for corrosion
and looseness. If there is a poor contact due
to corrosion or paint, wipe out the contact area
and retighten it.
Wiring mounting bolt to body
ground (-): 17 Nm
Measuring the battery voltage ▶
Stop the engine and wait for 20 minutes.
Measure the voltage between terminal (+)
and terminal (-) with the ignition switch OFF
and all electric devices OFF. -
Specified valueover 12V
