Swirl control valve
It operates variably in accordance with the
engine load and rpm.
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.

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

Inspection
Start the engine and turns on the headlamp, blower and heated wire at their full load. Then, measure
the maximum output current (MSM measurement value) when racing the engine to 2,700 rpm. 1.
Specified value60% of rated current (limit)
Turn the ignition OFF after inspection.
Disconnect the negative cable from the battery and remove the testers (ammeter and
voltmeter). 2.
3.
Characteristic curve (output from alternator)
The output current may not reach the limit value due to various parameters (high temperature or
electric load etc.). Thus, do not perform the inspection with fully charged battery.

5. INSPECTION - REGULATING VOLTAGE
Perform the basic inspection. -
Setting up the testers
Preparation
Set up the ammeter and voltmeter as shown
in the figure. 1.
Inspection
Turn the ignition ON and measure the voltage on the voltmeter. 1.
Start the engine and turn all electric devices OFF.
Increase the engine speed to 2,700 rpm and maintain the speed. Measure the voltage when the
output current from alternator decrease below 30A. 2.
3.
Specified valueover 12V
Specified value11.5 ~ 15.5V
Make sure to set up the tester while keeping
its polarity.

8. DTC SETTING CONDITIONS
Charge warning lamp ON condition
Turn the ignition ON (Engine stopped)
Open or short circuit of L terminal wiring, open or short internal circuit of alternator (fixed control of
13.8V)
Open or short circuit of F terminal wiring, no feedback output signal 1.

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -
10 A 15 A
Make sure to turn "OFF" the ignition switch
and other lamp switches before disconnecting
or connecting the negative battery cable.
(Otherwise, semiconductor parts can be
damaged.)
