Fuel Gage Inaccurate or Inoperative - Dual Tanks

DIAGNOSTIC AIDS
- Ensure that the fuel level is in the same range as the customer concern.
- For intermittent diagnosis, refer to Testing for Intermittent and Poor Connections.
- Use the fuel sender resistance (40-250 ohms) to verify the fuel sender operation. When the fuel tank is empty, the sender resistance is approximately 40 ohms and when the fuel tank is full the sender resistance is approximately 250 ohms.
