5. 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) 250 ohms (±10) Empty
Center position (tank half full) 141 ohms (±8) Half full
Upper position (tank full) 33.3 ohms (±6) Full
5.1. If the readings are within the specifications listed above, the fuel level sending unit is working properly.
5.2. If the readings are incorrect, the fuel level sending unit has failed and the fuel pump module must be
replaced.
5.3. If the readings are correct and the fuel gauge does not function correctly, go to step 5.3.1. Leave the
battery disconnected while checking continuity.
5.3.1. Check the continuity of the orange wire from the fuel level sending unit to the orange wire on
the fuel gauge/hour meter.
5.3.2. Check the continuity of the red/white wire from the fuel gauge/hour meter to the blue wire on the
key switch.
5.3.3. Check the continuity of the black ground wire at the fuel level sending unit.
5.3.4. Check the continuity of the black ground wires at the fuel gauge/hour meter.
6. 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.
