OPERATIONS AFTER ENGINE IS WARMED UP

PERIODIC INSPECTION AND MAINTENANCE

9. If there is a deviation from the standard value,

check the following items:

• Diagnosis output

• Fuel pressure

• Injector

• Ignition coil, spark plug cable, spark plug

• EGR control system

• Evaporative emission control system

• Compression pressure

NOTE:

Replace the three way catalyst when the CO and
HC contents are not within the standard value,
even though the result of the inspection is normal
on all items.

E8. CHECK EXHAUST GAS
RECIRCULATION (EGR) SYSTEM

M6020600800096

EGR CONTROL VALVE CHECK

1. Remove the EGR valve and inspect for sticking,

carbon deposits, etc. If found clean with a suitable
solvent so that the valve seats correctly.

2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the

vacuum is maintained.

4. Apply a vacuum and check the passage of air by

blowing through one side of the EGR passage.

5. Replace the gasket, and tighten to the specified

torque.

Tightening torque:

21

± 4 N⋅m <4G1>

20

± 2 N⋅m <4G6>

EGR CONTROL SOLENOID VALVE
CHECK <4G1>

NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid

valve.

2. Disconnect the harness connector.

3. Connect a hand vacuum pump to nipple (A) of the

solenoid valve.

4. Check air tightness by applying a vacuum with

voltage applied directly from the battery to the
EGR control solenoid valve and without applying
voltage.

5. Measure the resistance between the terminals of

the solenoid valve.

Standard value: 29

− 35 Ω (at 20°C)

OTHERS

F1. CHECK BODY CONDITION FOR
DAMAGE

M6020700100027

1. Check underbody coating for damage.
2. Check body painting for damage.

F2. ROAD TEST

M6020700200080

Drive the vehicle and check for conditions.
1. Check free play of steering wheel.
2. Check efficiency of service brakes and parking

brakes system.

3. Check driveability of engine.
4. Check condition of instruments, gauges

indicators, exterior lamps, heater and ventilators.

5. Check abnormal noise of each part.
6. Check the tyres for wear and for the correct air

pressure.
