Fuel Gauge Sender: Testing and Inspection

INSPECTION

FUEL GAUGE
1. Disconnect the fuel sender connector from the fuel sender.
2. Connect a 3.4 wattages, 12V test bulb to terminals 2 and 3 on the wire harness side connector.
3. Turn the ignition switch to the ON, and then check that the bulb lights up and the fuel gauge needle moves to full.





FUEL SENDER
1. Using an ohmmeter, measure the resistance between terminals 2 and 3 at each float level.




2. Also check that the resistance changes smoothly when the float is moved from "E" to "F".





3. If the height resistance is unsatisfied, replace the fuel sender as an assembly.

CAUTION:
After completing this test, wipe the sender dry and reinstall it in the fuel tank.
