Engine Oil Pressure: Testing and Inspection
INSPECTION1. Remove the collector cover.
2. Remove the oil pressure switch from engine cylinder block.
3. Connect the oil pressure gauge hose to cylinder block.
4. Connect the battery ground cable to battery.
5. Start the engine, and measure the oil pressure.
Oil pressure (Standard):
At 800 rpm 98 kPa (1.0 kgf/cm2, 14 psi) or more
At 5,000 rpm 294 kPa (3.0 kgf/cm2, 43 psi) or more
CAUTION:
^ If the oil pressure is out of specification, check oil pump, oil filter and lubrication line.
^ If the oil pressure warning light is turned to ON and oil pressure is within specification, replace the oil pressure switch.
NOTE: The specified value is based on an engine oil temperature of 80°C (176°F).
6. After measuring the oil pressure, install the oil pressure switch.
