Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a wiring diagram for reference.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Remove the Instrument Cluster
  • Remove the dashboard trim surrounding the instrument cluster using a trim tool.
  • Unscrew the instrument cluster mounting screws and carefully pull it out.
  • Disconnect the electrical connectors from the back of the cluster.
3. Inspect the Fuel Sending Unit
  • Access the fuel tank by removing the rear seat or trunk panel (depending on the model).
  • Disconnect the electrical connector from the fuel sending unit.
  • Remove the fuel sending unit by unscrewing the retaining ring and lifting it out of the tank.
  • Inspect for any signs of damage, corrosion, or debris.
4. Test the Fuel Sending Unit
  • Using a multimeter, measure the resistance across the sending unit terminals while moving the float arm.
  • Compare the readings with the specifications in the service manual (usually around 0-90 ohms).
  • If readings are outside specifications, replace the fuel sending unit.
5. Reassemble
  • If the sending unit was replaced, install the new unit back into the tank and secure it with the retaining ring.
  • Reconnect the electrical connector and reassemble the access panel or rear seat.
  • Reconnect the instrument cluster connectors and secure it back into position, followed by reattaching the dashboard trim.
