TEST PROCEDURE 26 – Fuel Level Sending Unit
See General Warning on page 10-1.
WARNING
• To avoid the possibility of fire or explosion, make sure the fuel tank cap is securely in place while
performing this test procedure.
1. Disconnect battery and spark plug wire(s). See Disconnecting the Battery – Gasoline Vehicles, Section 10,
Page 10-2.
2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2k ohms, place the red (+) probe of the multimeter on the center post of the sending unit.
Place the black (–) probe on the ground connection of the sending unit
(Figure 11-42, Page 11-42) .
4. The following resistance readings (in ohms) should be obtained depending on the position of the float inside
the fuel tank. The resistance reading will vary according to the exact position of the float. The chart below may
be used as a guideline to determine if the fuel level sending unit is operating correctly. Make sure the float
is at the surface of the fuel in the tank.
FLOAT POSITION RESISTANCE READING FUEL GAUGE READINGS
Lower position (tank empty) 240 ± 20 ohms Empty
Center position (tank half full) 120 ± 20 ohms Half full
Upper position (tank full) 60 ± 20 ohms Full

5. If the readings are within the specifications listed above, the fuel level sending unit is working properly. If the
readings are incorrect, the fuel level sending unit has failed and the fuel tank must be replaced.
See Fuel
Tank Removal on page 15-25.
6. If the readings are correct and the fuel gauge does not function correctly, check the continuity of the orange wire
from the fuel level sending unit to the fuel gauge/hour meter. Leave the battery disconnected while checking
continuity. Also check the continuity of the blue wire from the fuel gauge/hour meter to the key switch, and the
black ground wires at the fuel level sending unit and at the fuel gauge/hour meter.
See Fuel Gauge/Hour
Meter Removal on page 12-26.
7. If the readings are correct according to the position of the float, but give an incorrect reading on the fuel
gauge/hour meter, test the fuel gauge/hour meter.
See Test Procedure 27 – Fuel Gauge on page 11-43.
