Engine Oil Pressure Test

Special Tools Required
Oil pressure gauge attachment ( 07406-0030000)

Oil pressure gauge ( 07506-3000001)

If 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 the special tools.

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: 80°C (176°F)
Engine Oil Pressure:
At Idle: 70 kPa (0.7 kgf/cm², 10 psi) minimum
At 3,000 rpm (min^-1): 340 kPa (3.5 kgf/cm², 50 psi) minimum

5. If the oil pressure is NOT within specification, inspect these items.

Check the oil screen for clogging.
Check the oil pump.
