Oil pump discharge pressure measurement
NOTE:
Prior to checking oil pressure, check the following.
Oil level in oil pan.
If level is low, add oil up to Full level hole on oil level gauge.
Oil quality.
If oil is discolored, or deteriorated, change oil. For particular
oil to be used, refer to table in SECTION 0B MAINTENANCE
SERVICE.
Oil leak.
If leak is found, repair it.

(A): 09915-77310
4) Start engine and warm it up to normal operating temperature.
5) After warming up, raise engine speed to 3,000 r/min and mea-
sure oil pressure.
6) After checking oil pressure, stop engine and remove oil pres-
sure gauge.
7) Before reinstalling oil pressure switch, be sure to wrap its screw
threads with sealing tape and tighten switch to specified torque.
Tightening Torque
Oil pressure switch: 14 N·m (1.4 kg-m, 10.5 Ib-ft).
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut off edge.
8) After installing oil pressure switch, start engine and check
switch for oil leakage.
