E4.
REPLACE ENGINE OIL FILTER
(1) Start the engine and allow it to warm up until the
temperature of the coolant reaches 80
_C to 90_C.
(2) Remove the engine oil filler cap.
(3) Remove the drain plug to drain oil.
Caution
Use care as oil could be hot.
(4) Remove the under cover.
(5) Use the respective tool in the following table to remove
the engine oil filter.
(6) Clean the filter bracket side mounting surface.
(7) Apply a small amount of engine oil to the O-ring of the
new oil filter.
(8) Once the O-ring of the oil filter is touching the flange,
use the respective tool in the following table to tighten to
the specified torque.
(9) Install the drain plug and refill the engine oil.
(10)Race the engine 2-3 times, and check to be sure that no
engine oil leaks from installation section of the oil filter.

E5.
CHECK ENGINE IDLING SPEED
(1) Before inspection, set the vehicle to the pre-inspection
condition.
(2) Turn the ignition switch to “LOCK” (OFF) position.
(3) Connect the MUT-
II/III to the diagnosis connector or
connect a tachometer to the engine speed detection
connector.
(4) Connect a timing light.
(5) Start the engine and let it run at idle.
(6) Check that ignition timing is at the standard value.
Standard value:
approximately 10
_ BTDC <4G1>
approximately 5
_ BTDC <4G6>
(7) Check the idle speed.
Standard value: 750
± 100 r/min
NOTE
1.
The idle speed is controlled automatically by the idle
speed control system.
2.
When using the MUT-
II, select item No.22 and take
a reading of the idle speed.
(8) If the idle speed is outside the standard value, inspect
the MPI system (Refer to WORKSHOP MANUAL
GROUP 13 -- Troubleshooting).
E6.
CHECK CO CONCENTRATION
(1) Before inspection, set the vehicle to the pre-inspection
condition.
(2) Turn the ignition switch to “LOCK” (OFF) position.
(3) Connect the MUT-
II/III to the diagnosis connector or
connect a tachometer to the engine speed detection
connector.
(4) Connect a timing light.
(5) Start the engine and let it run at idle.
(6) Check that ignition timing is at the standard value.
Standard value:
approximately 10
_ BTDC <4G1>
approximately 5
_ BTDC <4G6>
(7) Run the engine at 2,500 r/min for 2 minutes.
(8) Set the CO, HC tester.

(9) Check the CO contents and the HC contents at idle.
Standard value
CO contents:
0.5% or less <4G1>
0.6% or less <4G6>
HC contents: 100 ppm or less
(10)If there is a deviation from the standard value, check the
following items:
D Diagnosis output
D Fuel pressure
D Injector
D Ignition coil, spark plug cable, spark plug
D EGR control system
D Evaporative emission control system
D 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
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.
Vacuum
Passage of air
5.3 kPa or less
Air is not blown out
27 kPa or more
Air is blown out
(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 (refer to the illustration at left).
(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)
EGR CONTROL SOLENOID VALVE CHECK <4G6>
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 (refer to the illustration at left).
(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.
