Oil Pressure Gauge: Testing and Inspection
Oil Pressure Gauge/Oil Pressure Switch
With the tester attached to the oil pressure switch connector and the ignition switch lock cylinder in the RUN position (engine not running), set the
tester to infinite resistance. The center line of the pointer should fall on or below the "L" mark.
Short the connector directly to engine ground. The centerline of the pointer should fall slightly above mid-scale.
-
If the oil pressure gauge (9273) tests within calibration, replace the oil pressure switch.
-
If the oil pressure gauge still tests out of calibration, replace the gauge.
