Engine Coolant Temperature Receiver Gauge: Testing and Inspection

1. INSPECT ENGINE COOLANT TEMPERATURE 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 COOL.

c. Ground terminal on the wire harness side connector through a 3.4 W test bulb.
d. Turn the ignition switch ON, and check that the bulb lights up and the receiver gauge needle moves to the hot side.

If operation is as specified. replace the sender gauge. Then, recheck the system.

If operation is not as specified, measure the receiver gauge resistance.
