Component Inspection
INSPECT ENGINE COOLANT TEMPERATURE RECEIVER GAUGE OPERATIONa. 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 toward the hot side.
Then recheck the system.
If operation is not as specified, measure the receiver gauge resistance.
INSPECT ENGINE COOLANT TEMPERATURE RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
HINT: Connect the test leads so the current from the ohmmeter can flow according to the chant order.
If resistance value is not as specified, replace the engine coolant temperature receiver gauge.
