Solution
1. Preparation
  • Tools Required:
    • OBD-II scanner
    • Multimeter
    • Socket set
    • Screwdriver set
    • Torque wrench
  • Disconnect the vehicle's battery to prevent electrical shorts or shocks.
2. Remove Instrument Cluster
  • Using a screwdriver, carefully remove the screws securing the instrument cluster.
  • Gently pull the cluster out and disconnect the wiring harness from the back.
3. Inspect and Test Fuel Sender Unit
  • Location: The fuel sender unit is located in the fuel tank.
  • Remove the rear seat or access panel to gain access to the fuel pump module.
  • Disconnect the wiring harness from the fuel pump and sender unit.
  • Use a multimeter to measure the resistance of the sender unit:
    • At full tank, resistance should be around 0 ohms.
    • At empty tank, resistance should be around 90 ohms.
  • If the readings are outside this range, replace the fuel sender unit.
4. Check Wiring and Connectors
  • Inspect all wiring and connectors for damage or corrosion.
  • Clean any corroded connectors and ensure they are securely connected.
  • Repair or replace any damaged wiring as necessary.
5. Reassemble and Test
  • Reconnect the fuel sender unit and wiring harness.
  • Reinstall the instrument cluster by reversing the removal steps.
  • Reconnect the vehicle's battery.
