Fuel Gauge Sender: Service and Repair

Checking The Fuel Gauge Float Arm Position







With the pump placed on a level surface, the distance between the surface and the bottom of the float should be 0-3 mm.

The sensor resistance should be:
Tank empty, float in bottom position: 50 ±1.5 ohms.
Tank full, float in top position: 425 ±6.5 ohms.
