Oil Pressure Check
Oil level in oil pan.
If oil level is low, add oil up to Full level mark (hole) (1) on oil
level gauge.
Oil quality.
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to the table in Section 0B.
Oil leaks.
If leak is found, repair it.
1) Disconnect oil pressure switch coupler (1) and remove oil
pressure switch (2) from cylinder block.
2) Install special tools (Oil pressure gauge) to vacated threaded
hole.
Special tool
(A) : 09915-77310
(B) : 09915-78211
3) Start engine and warm it up to normal operating tempera-
ture.
4) After warming up, raise engine speed to 4,000 rpm and mea-
sure oil pressure.
Oil pressure specification
280 – 430 kPa (2.8 – 4.3 kg/cm
2, 39.8 – 61.1 psi) at 4,000
rpm
5) Stop engine and remove oil pressure gauge and attachment.NOTE:
Prior to checking oil pressure, check the following items.
2. Low level mark (hole)
NOTE:
Be sure to place transmission gear shift lever in “Neu-
tral” (shift selector lever to “P” range for A/T model), and
set parking brake and block drive wheels.

Flywheel
If ring gear is damaged, cracked or worn, replace flywheel.
If the surface contacting clutch disc is damaged, or exces-
sively worn, replace flywheel.
Check flywheel for face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Flywheel runout
Limit : 0.2 mm (0.0079 in.)
Sensor Plate
Check sensor plate for crack or damage. If malcondition is
found, replace it.
Cylinder Block
Distortion of gasketed surface
Using straightedge and thickness gauge, check gasketed
surface for distortion and, if flatness exceeds its limit, correct
it.
Cylinder block flatness
Limit : 0.05 mm (0.0020 in.)
Honing or reboring cylinders
1) When any cylinder needs reboring, all other cylinders must
also be rebored at the same time.
2) Select oversized piston according to amount of cylinder
wear.

On-Vehicle Service
Accelerator cable adjustment
1) With throttle valve closed, check accelerator pedal play
which should be within following specification.
If measured value is out of specification, adjust it to specifi-
cation with cable adjusting nut (1).
Accelerator pedal play
“a” : 2 – 7 mm (0.08 – 0.27 in.)
2) With accelerator pedal depressed fully, check clearance
between throttle lever (2) and lever stopper (3) (throttle
body) which should be within following specification.
If measured value is out of specification, adjust it to specifi-
cation by changing height of pedal stopper bolt (1).
Accelerator cable adjustment clearance
(With pedal depressed fully)
“a” : 0.5 – 2.0 mm (0.02 – 0.07 in.)
Idle speed / idle air control (IAC) duty inspection
Before idle speed / IAC duty check, make sure of the following.
Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.
Accelerator cable has some play, that is, it is not tight.
Valve lash is checked and adjusted according to mainte-
nance schedule.
Ignition timing is within specification.
All accessories (wipers, heater, lights, A/C, etc.) are out of
service.
Air cleaner has been properly installed and is in good condi-
tion.
No abnormal air inhaling from air intake system.
After above items are all confirmed, check idle speed and IAC
duty as follows.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
vehicle), and set parking brake and block drive wheels.

Fuel cut operation
INSPECTION
1) Warm up engine to normal operating temperature.
2) While listening to sound of injector (1) by using sound scope
(2) or such, increase engine speed to higher than 3,000 r/
min.
3) Check to make sure that sound to indicate operation of injec-
tor stops when throttle valve is closed instantly and it is
heard again when engine speed is reduced to less than
about 2,000 r/min.
A/C condenser fan control system
SYSTEM INSPECTION
Check system for operation referring to “Flow Table B-7” in Sec-
tion 6.
If A/C condenser fan fails to operate properly, check relay, A/C
condenser fan and electrical circuit.
A/C condenser fan
INSPECTION
1) Check continuity between each two terminals.
If there is no continuity, replace A/C condenser fan motor. NOTE:
Before inspection, check to make sure that gear shift
lever is in neutral position (with A/T model, selector lever
in “P” range), A/C is OFF and that parking brake lever is
pulled all the way up.
WARNING:
Keep hands, tools, and clothing away from A/C con-
denser fan to help prevent personal injury. This fan is
electric and can come on whether or not the engine is
running. The fan can start automatically in response to
the ECT sensor with the ignition switch in the “ON” posi-
tion.

REMOVAL
1) Disconnect negative cable at battery.
2) Disconnect EGR valve connector.
3) Remove EGR pipe.
4) Remove EGR valve and gasket from cylinder head.
INSPECTION
1) Check resistance between following terminals of EGR valve
(1) in each pair.
If found faulty, replace EGR valve assembly.
