Oil Pressure Check

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.
Oil quality
If oil is discolored, or deteriorated, change it. For particular oil to be used, refer to ENGINE OIL AND FILTER CHANGE .
Oil leaks
If leak is found, repair it.

Disconnect oil pressure switch connector.
Remove oil pressure switch (1) from cylinder block.

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.
After warming up, raise engine speed to 4,000 rpm and measure oil pressure.
Oil pressure specification

More than 390 kPa (3.9 kg/cm² , 55.5 psi)
After checking oil pressure, stop engine and remove oil pressure gauge.
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: 15 N.m (1.5 kg-m, 11.0 lb-ft)

NOTE: If sealing tape edge is bulged out from screw threads of switch, cut it off.
