Oil Pressure Check
Prior to checking oil pressure, check the following items.
Oil level in oil pan
If oil level is low, add oil up to Full level mark (hole) (1) on oil level gauge.
2. Low level mark (hole)
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.
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 temperature.
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.
4) After warming up, raise engine speed to 4,000 r/min. and measure oil pressure.
Oil pressure specification
280 – 430 kPa (2.8 – 4.3 kg/cm², 39.8 – 61.1 psi) at 4,000 r/min. (rpm)
5) Stop engine and remove oil pressure gauge and attachment.
6) Before reinstalling oil pressure switch (2), be sure to wrap its screw threads with sealing tape (1) and tighten switch to specified torque.
If sealing tape edge is bulged out from screw threads of switch, cut it off.
Tightening torque
Oil pressure switch ( a ): 14 N·m ( 1.4 kg-m, 10.5 lb-ft)
7) Start engine and check oil pressure switch for oil leakage. If oil leakage is found, repair it.
8) Connect oil pressure switch coupler (1).
