Oil pressure:
Standard
98 kPa (1.0 kg/cm2, 14 psi) or more at 600 rpm
294 kPa (3.0 kg/cm2, 43 psi) or more at 5,000 rpm
CAUTION:
^ If the oil pressure is out of standard values, check the oil pump, oil filter and lubrication line.
^ If the oil pressure warning light is turned ON and oil pressure is in the specified range, replace the oil pressure switch.
NOTE: Standard value is based on an engine oil temperature of 80°C (176°F).
5. After measuring the oil pressure, install the oil pressure switch.
