EGR VOLUME CONTROL SYSTEMPFP:14710
DescriptionEBS0035N
SYSTEM DESCRIPTION
This system controls flow rate of EGR led from exhaust manifold to intake manifold. The opening of the EGR
by-pass passage in the EGR volume control valve changes to control the flow rate. A built-in step motor
moves the valve in steps corresponding to the ECM output pulses. The opening of the valve varies for opti-
mum engine control. The optimum value stored in the ECM is determined by considering various engine con-
ditions.
The EGR volume control valve remains close under the following conditions.
lEngine stopped
lEngine starting
lLow engine coolant temperature
lExcessively high engine coolant temperature
lHigh engine speed
lWide open throttle
COMPONENT DESCRIPTION
EGR Volume Control Valve
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.

ValveLifterHoleDiameter
lUsing inside micrometer, measure diameter of valve lifter hole of
cylinder head.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (hole diameter of valve lifter) – (outer diam-
eter of valve lifter).
lWhen out of specified range, referring to each specification of outer and inner diameter, replace either or
both valve lifter and cylinder head.
Valve ClearanceEBS009R1
INSPECTION
lPerform inspection as follows after removal, installation or replacement of camshaft or valve-related parts,
or if there is unusual engine conditions due to changes in valve clearance over time (starting, idling, and/
or noise).
1. Warm up engine. Then stop it.
2. Remove front RH engine side cover.
3. Remove rocker cover.
Refer toEM-31, "
Removal and Installation".
4. Turn crankshaft pulley in normal direction (clockwise when
viewed from front) to align TDC identification notch (without
paint mark) with timing indicator.
5. At this time, check that the both intake and exhaust cam noses
of No. 1 cylinder face outside.
lIf they do not face outside, turn crankshaft pulley once more. Standard:
34.000 - 34.021 mm (1.3386 - 1.3394 in)
Standard:
0.020 - 0.056 mm (0.0008 - 0.0022 in)

PRECAUTIONS
Precautions for Multiport Fuel Injection System or Engine Control System
EAS000FT
lBefore connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS000FU
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after start-
ing.
lIf engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS000FV
HOSE REMOVAL AND INSTALLATION
lTo prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
lTo reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
GI-27
Cold or Hot Start Up
On some occasions an electrical incident may occur only when the car is started cold, or it may occur when
the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to
make a proper diagnosis.
CIRCUIT INSPECTION
Introduction
In general, testing electrical circuits is an easy task if it is approached in a logical and organized method.
Before beginning it is important to have all available information on the system to be tested. Also, get a thor-
ough understanding of system operation. Then you will be able to use the appropriate equipment and follow
the correct test procedure.
You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring har-
ness or electrical component to do this.
NOTE:
Refer to "How to Check Terminal” to probe or check terminal.
Testing for “Opens” in the Circuit
Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This
will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your work-
ing knowledge of the system.
CONTINUITY CHECK METHOD
The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance
function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure to always start
with the DMM at the highest resistance level.
To help in understanding the diagnosis of open circuits, please refer to the previous schematic.
lDisconnect the battery negative cable.
lStart at one end of the circuit and work your way to the other end. (At the fuse block in this example)
lConnect one probe of the DMM to the fuse block terminal on the load side.
lConnect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that
portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an
over limit or infinite resistance condition. (point A)
lConnect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the cir-
cuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infi-
nite resistance condition. (point B)
lConnect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of
the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or
infinite resistance condition. (point C)
OPENA circuit is open when there is no continuity through a section of the circuit.
SHORTThere are two types of shorts.
lSHORT CIRCUITWhen a circuit contacts another circuit and causes the normal resistance to
change.
lSHORT TO GROUND When a circuit contacts a ground source and grounds the circuit.

LIFTING POINTPFP:00000
Special Service ToolsEAS000FH
CAUTION:
lEvery time the vehicle is lifted up, maintain the complete vehicle curb condition.
lSince the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.
lSince the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.
lBe careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety StandEAS000FI
WA RN ING:
lPark the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.
lNever get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.
