Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative terminal of the battery to ensure safety while working with electrical components.
2. Inspect Fuel Gauge Fuse
  • Locate the fuse box (refer to the owner's manual for specific location).
  • Remove the fuel gauge fuse using a fuse puller.
  • Inspect the fuse for continuity; replace it with an identical rated fuse if blown.
3. Access Fuel Level Sender Unit
  • Raise the vehicle securely on jack stands.
  • Remove the access panel or fuel tank cover to reach the fuel level sender unit (if applicable).
  • Disconnect the electrical connector from the fuel level sender.
4. Test Fuel Level Sender
  • Use a multimeter to measure the resistance of the fuel level sender unit:
    • Connect the multimeter leads to the sender terminals.
    • At full tank, the resistance should be low (typically around 10-15 ohms), and at empty, it should be high (typically around 100-150 ohms).
  • Replace the fuel level sender unit if readings are out of range.
5. Reassemble and Test
  • Reconnect the fuel level sender electrical connector.
  • Reinstall the access panel or fuel tank cover.
  • Reconnect the negative terminal of the battery.
  • Start the vehicle and check the fuel gauge for proper operation.
