Engine Lubrication System: For J20 Engine 1E-13
Diagnostic Information and Procedures
Oil Pressure Check
S5JB0A1524001
WARNING
!
To avoid danger of being burned, do not
touch exhaust manifold when exhaust
system is hot.
When servicing, be sure to perform it after
exhaust system has cooled down.
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
hole 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 connector.
2) Remove oil pressure switch (1) from cylinder block.
3) Install special tool (Oil pressure gauge) to vacated
threaded hole.
Special tool
(A): 09915–77311
(B): 09915–78211
CAUTION
!
Be careful not to make special tool touch
Exhaust manifold when installing because
Exhaust manifold becomes very hot.
4) Start engine and warm it up to normal operating
temperature.
NOTE
Be sure to place transmission gear shift lever
in “Neutral” (shift selector lever to “P” range
for A/T model), and set parking brake and
block drive wheels.
5) After warming up, raise engine speed to 4,000 rpm
and measure oil pressure.
Oil pressure specification
More than 390 kPa (3.9 kg/cm
2
, 55.5 psi)
6) After checking oil pressure, stop engine and remove
oil pressure gauge.
7) Before reinstalling oil pressure switch (2), be sure to
wrap its screw threads with sealing tape (1) and
tighten switch to specified torque.
Tightening torque
Oil pressure switch (a): 13 N·m (1.3 kgf-m, 9.5
lb-ft)
NOTE
If sealing tape edge is bulged out from screw
threads of switch, cut it off.
8) Start engine and check oil pressure switch for oil
leakage. If oil leakage is found, repair it.
9) Connect oil pressure switch coupler.
