Fuel Temperature Sensor: Testing and Inspection

1. Connect fuel gauge unit to battery via test light (12 V-3.4 W). Immerse it in water.
2. The condition is good if light goes off when thermistor is in water and lights when it is removed from water.

CAUTION: Dry the unit, or water will get into the fuel tank.
