Engine Oil Pressure: Testing and Inspection
Engine Oil PressureINSPECTION
1) Disconnect the ground cable from battery.
2) Remove the oil pressure switch.
3) Attach the oil pressure gauge to the cylinder block.
4) Connect the ground cable to battery.
5) Start the engine, and measure the oil pressure.
NOTE:
^ Standard value is based on an engine oil temperature of 80 degrees C (176 degrees F).
^ 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.
Engine oil pressure:
Standard
98 kPa (1.0 kgf/cm2, 14 psi) or more at 600 rpm
294 kPa (3.0 kgf/cm2, 43 psi) or more at 5,000 rpm
6) After inspection, install the related parts in the reverse order of removal.
