Fuel Receiver Gauge Malfunction [08/2013 - ]: Description

• The meter ECU uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank. The resistance of the fuel sender gauge will vary between approximately 13 Ω with the float at the full position, and 414 Ω with the float at the empty position. The meter outputs battery voltage through two resistors that are mounted inside the meter ECU. The meter ECU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in the meter. Voltage measured at this point will vary as the float of the fuel sender gauge is moved. The highest voltage observed should be approximately half of the battery voltage.

HINT: 

The fuel level warning light will come on when the fuel level is below 9.7 liters (10.3 US qts, 8.5 Imp.qts).
