Engine Oil PressureINSPECTION
1) Disconnect the ground cable from battery.
2) Remove the oil pressure switch.
3) Install the oil pressure gauge to cylinder block.
4) Connect the battery ground terminal.
5) Start the engine, and check the oil pressure.
NOTE:
^ Standard value is based on an engine oil temperature of 80°C (176°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.
