Instrument Panel and Gauges for Fuel Gauge testing. 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.
