Solution
1. Preparation
  • Tools Needed: OBD-II scanner, multimeter, screwdriver set, wiring harness repair kit (if needed)
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect Fuel Level Sensor
  • Locate the fuel level sensor, typically found in the fuel tank assembly.
  • Remove the fuel tank access cover (if applicable).
  • Disconnect the wiring harness from the fuel level sensor.
  • Use a multimeter to measure the resistance across the sensor terminals:
    • At empty, resistance should be around 0 ohms.
    • At full, resistance should be around 90-120 ohms (check service manual for exact specifications).
  • If readings are outside specifications, replace the fuel level sensor.
3. Check Instrument Cluster
  • If the sensor is functioning, the issue may lie within the instrument cluster.
  • Remove the instrument cluster from the dashboard by unscrewing it and gently pulling it out.
  • Inspect the connectors and wiring for any signs of damage.
  • If no damage is found, consider replacing the instrument cluster.
4. Reassemble Components
  • Reconnect all wiring harnesses securely.
  • Reinstall the fuel tank access cover and instrument cluster.
  • Reconnect the negative battery terminal.
