Fuel Gauge Sender: Testing and Inspection

NOTE: This article contains changes called out by TSB# PG008-05.




INSPECT FUEL RECEIVER GAUGE OPERATION
a. Disconnect the connector from the main sender gauge.
b. Turn the ignition switch ON, check that the receiver gauge needle indicates EMPTY.




c. Connect the main sender gauge.
d. Disconnect the connector from the sub sender gauge.
e. Turn the ignition switch ON, check that the receiver gauge needle indicates EMPTY.

HINT: Because of the silicon oil in the gauge, it will take a short time for needle to stabilize.

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







INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals with fixing pointer to the stopper.
If resistance value is not as specified, replace the receiver gauge.







INSPECT FUEL MAIN SENDER GAUGE RESISTANCE
Measure the resistance between terminals 1 and 2 for each float position.
If resistance value is not as specified, replace the main sender gauge.







INSPECT FUEL SUB SENDER GAUGE RESISTANCE
Measure the resistance between terminals 1 and 2 for each float position.
If resistance value is not as specified, replace the sub sender gauge.







INSPECT SPECIFIC FUEL CONSUMPTION GAUGE RESISTANCE
Measure the resistance between terminals with fixing pointer to the stopper.
If resistance value is not as specified, replace the meter.
