Engine Oil Pressure: Testing and Inspection
Engine Oil PressureINSPECTION
1. Remove the oil pressure switch from the cylinder block.
2. Connect the oil pressure gauge hose to the cylinder block.
3. Connect the ground cable to battery.
4. Start the engine, and measure the oil pressure.
OIL PRESSURE (at oil temperature of 80 degrees C (176 degrees F)):
Standard:
135 kPa (1.4 kgf/cm2, 20 psi) or more (at 600 rpm)
500 kPa (5.1 kgf/cm2, 73 psi) or more (at 5,000 rpm)
^ If the oil pressure is out of specification, check oil pump, oil filter and lubrication line.
^ If the oil pressure warning light is ON and oil pressure is within specification, check the oil pressure switch.
5. After measuring the oil pressure, install the oil pressure switch.
