Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working with electrical components.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box under the dashboard or hood.
Identify the fuse responsible for the fuel gauge (refer to the owner's manual).
Remove the fuse and check for continuity; replace if blown.

3. Check Fuel Level Sender Unit

Tools Required: Multimeter, socket set
Access the fuel tank by removing the rear seat or accessing the trunk area (depending on model).
Disconnect the electrical connector from the fuel level sender unit.
Use the multimeter to measure the resistance across the sender unit terminals. Resistance should vary as the float moves.
- If resistance is constant or outside specified range, replace the fuel level sender unit.

4. Inspect Instrument Cluster

Tools Required: Screwdriver set
Remove the dashboard panel to access the instrument cluster.
Check for loose connections or damaged wiring.
If no visible issues are found, consider replacing the instrument cluster.

5. Reassemble and Test

Reconnect any electrical connectors and reassemble the dashboard.
Reconnect the battery.
If any components were replaced, ensure they are properly secured.
