Fuel Receiver Gauge Malfunction

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 15 ohms with the float at the full position, and 410 ohms with the float at the empty position. The meter outputs battery voltage through two 820 ohms resistors that are mounted in parallel inside the meter ECU. 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 battery voltage.

HINT: The fuel level warning light will come on when the fuel level is below 10.5 liters.
