Oil Pressure Gauge: Testing and Inspection

1. INSPECT OIL PRESSURE RECEIVER GAUGE OPERATION





a. Disconnect the connector from the sender gauge.
b. Turn the ignition switch ON, and check that the receiver gauge needle indicates LOW.





c. Ground terminal on the wire harness side through a 3.4 W test bulb.
d. Turn the ignition switch ON, and check that the bulb lights up and that the receiver gauge needle moves to the high side.
If operation is not as specified, measure the receiver gauge resistance.





2. INSPECT OIL PRESSURE RECEIVER GAUGE RESISTANCE
Measure the receiver gauge resistance between terminals.
Resistance: 40-48 Ohms.
If resistance value is not as specified, replace the receiver gauge.
