Low Fuel Lamp/Indicator: Testing and Inspection

The low fuel warning lamp receives its signal from the fuel gauge drive circuit. Due to production variations, the point where the lamp illuminates, may vary from 1/16 to 3/16 mark on the fuel gauge. There is a built in time delay before the lamp illuminates. This prevents the lamp from going on and off under various road conditions.
1. Verify that the fuel gauge is operating properly
2. Check the low fuel warning lamp assembly
3. If the lamp still does not function under a low fuel condition replace the printed circuit board.
