Fuel Gauge & Warning Light

1. Unplug connector at fuel tank sending unit. Connect a 12-volt, 3.4-watt test light between lead wire and ground. Turn ignition on. Test light should flash and needle should vibrate.
2. Turn ignition off. Connect ohmmeter to sending unit terminals. Move sender arm and ensure resistance varies within specifications. See FUEL SENDING UNIT RESISTANCE  table. Gauge pointer should move when sender is connected and float arm is moved.

   Model	Float Position	Ohms
   Camry	Full	2-5
   Camry	Empty	107-113
   Land Cruiser	Full	15-19
   Land Cruiser	Half	35-45
   Land Cruiser	Empty	113-127
   All Others	Full	1-5
   All Others	Half	28-37
   All Others	Empty	102-118

3. To check low fuel warning light sensor, remove fuel sender from tank. Connect battery voltage to sensor terminal. Connect a 12-volt 3.4-watt test light between body of sending unit and ground. With sensor dry, light should come on within 40 seconds. With sensor in gasoline or water, light should not come on.
4. Check gauge resistance by measuring across terminals with ohmmeter. See Fig 19-Fig 31 . Ignition must be off and connector unplugged. See FUEL & TEMPERATURE GAUGE RESISTANCE  table.
