highest pressure on compression gauge.
NOTE
• For measuring compression pressure,
crank engine at least 250 r/min. by using
fully charged battery.
• If measured compression pressure is
lower than limit value, check installation
condition of special tool. If it is properly
installed, possibility is compression
pressure leakage from where piston ring
and valve contact.

kPa (1.0 kgf/cm
2, 14.2 psi)
10) Carry out Steps 7) through 9) on each cylinder to
obtain 4 readings.
11) After checking, install spark plugs and ignition coil
assemblies with high-tension cord referring to “Spark

gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T model), and set
parking brake and block drive wheels.

2) Stop engine and turn off the all electric switches.
3) Remove air cleaner assembly with air suction hose
referring to “Air Cleaner Assembly Removal and
Installation”.
4) Remove PCV hose (1) from PCV valve (2).
5) Connect special tool (Vacuum gauge) to PCV hose
(1).

Diagnostic Information and Procedures
Oil Pressure CheckS6RW0D1504001
WARNING!
To avoid the danger of being burned, do not
touch the exhaust system when the system is
hot. Any service on the exhaust system
should be performed when the system is
cool.

NOTE
Prior to checking oil pressure, check the
following.
• Oil level in oil pan
If oil level is low, add oil up to full level
mark (hole) (1) on oil level gauge referring
to “Engine Oil and Filter Change in Section
0B”.
• Oil quality
If oil is discolored or deteriorated, change
it. For particular oil to be used, refer to
“Engine Oil and Filter Change in Section
0B”.
• Oil leaks
If leak is found, repair it.

1) Disconnect oil pressure switch coupler (1).
2) Remove oil pressure switch (2) from cylinder block.3) Install special tools (oil pressure gauge) to vacated
threaded hole of oil pressure switch.
Special tool
(A): 09915–77310
(B): 09915–78211
4) Start engine and warm engine up to normal
operating temperature.
NOTE
Be sure to shift transaxle gear shift lever in
“Neutral”, set parking brake and block drive
wheels.

5) After warming up, raise engine speed to 4,000 r/min.
and measure oil pressure.
Oil pressure specification
More than 270 kPa (2.7 kgf/cm2, 39.8 psi) at 4,000
r/min. (rpm)
6) After checking oil pressure, stop engine and remove
oil pressure gauge and attachment.
7) Before reinstalling oil pressure switch (2), be sure to
wrap its screw threads with sealing tape (1) and
tighten switch to specified torque.

stopped: 360 – 400 kPa (3.6 – 4.0 kgf/cm2,
51.2 – 56.9 psi)
b) Start engine and warm it up to normal operating
temperature, and measure fuel pressure at
idling.
Fuel pressure specification
At specified idle speed: 360 – 400 kPa (3.6 –
4.0 kgf/cm2, 51.2 – 56.9 psi)

minute after stopping.
Fuel pressure specification
With 1 min. after engine (fuel pump) stop
(Pressure reduces as time passes): Over 250
kPa (2.5 kgf/cm
2, 35.6 psi)
6) After checking fuel pressure, remove fuel pressure
gauge.
WARNING!
As fuel feed line is still under high fuel
pressure, make sure to release fuel pressure
according to the following procedures.
• Place fuel container under joint.
• Cover joint with rag (1) and loosen joint nut
slowly in order to release fuel pressure
gradually.
