Engine Oil Pressure: Testing and Inspection

Check oil pressure using gauge at oil pressure switch location. Oil pressure should be 34 kPa (5 psi) at idle or 205 - 550 kPa (30 - 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.
