METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

| Fuel Receiver Gauge Malfunction |
DESCRIPTION
The combination meter assembly uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank. The resistance of the fuel sender gauge assembly will vary between approximately 15 Ω with the float at the full position, and 410 Ω with the float at the empty position. The combination meter assembly outputs battery voltage through two resistors that are mounted inside the combination meter assembly. The combination meter assembly measures the voltage between the variable resistor in the fuel sender gauge assembly and the two resistors mounted in the combination meter assembly. Voltage measured at this point will vary as the float of the fuel sender gauge assembly is moved. The highest voltage observed should be approximately half of the battery voltage.
The fuel level warning light will come on when the fuel level is below 7.5 liters (7.9 US qts, 6.6 Imp. qts).

CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY, FUEL TANK VENT TUBE SUB-ASSEMBLY)
Disconnect the E46 combination meter assembly connector.
Disconnect the L20 fuel suction tube with pump and gauge assembly*1 or fuel tank vent tube sub-assembly*2 connector.
