Engine Oil Pressure: Testing and Inspection

Check oil pressure using gauge at oil pressure switch location. Oil pressure should be 34.47 kPa (5 psi) at idle or 205 to 551 kPa (30 to 80 psi) at 3000 RPM.
1. Remove pressure sending unit and install oil pressure gauge.

CAUTION: If oil pressure is 0 at idle, do not run engine at 3000 RPM.

2. Warm engine at high idle until thermostat opens.
