Fuel Level Sensor: Testing and Inspection
The fuel level sensor contains a variable resistor (track). As the float moves up or down, electrical resistance will change. To test the level sensor only, it
must be removed from vehicle. The unit is part of the fuel pump module. Refer to Fuel Pump Module Removal/Installation for procedures. Measure the
resistance across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6 ohms. With float in down position, resistance
should be 220 ohms ± 6 ohms.
