Fuel Receiver Gauge Malfunction: Description
- The meter CPU 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 13.5 Ω with the float at the full position, and 414.5 Ω with the float at the empty position. The meter outputs battery voltage through two 820 Ω resistors that are mounted in parallel inside the meter CPU. The meter CPU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in parallel 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.
NOTE:
When the combination meter is removed or replaced, its connector is disconnected or fuel is added, the fuel receiver gauge display will return to normal a maximum of 16 minutes after the engine switch is turned on (IG) or when vehicle speed is input.
HINT:
The fuel level warning light will come on when the fuel level is below 10.7 liters (11.3 US qts, 9.4 Imp.qts).
