Engine Oil Pressure: Testing and Inspection
Oil Pressure TestIf the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:
1. Connect a tachometer or a Honda PGM Tester.
2. Remove the engine oil pressure switch, and install an oil pressure gauge (A).
3. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
4. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
Engine Oil Temperature: 176°F (80°C)
Engine Oil Pressure:
At Idle: 70 kPa (0.7 kgf/cm2, 10 psi) minimum
At 3,000 rpm: 300 kPa (3.1 kgf/cm2, 44 psi) minimum
5. If the oil pressure is NOT within specification, inspect these items.
^ Check the oil strainer for clogging.
^ Check the oil pump.
