Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

  • OBD-II scanner
  • Multimeter
  • Socket set
  • Torque wrench
2. Inspect and Repair Fuel Sending Unit
  1. Access the Fuel Sending Unit:

    • Remove the rear seat or access panel to reach the fuel tank, depending on your Camry model year.
  2. Remove the Fuel Sending Unit:

    • Disconnect the fuel lines and electrical connectors from the sending unit.

    • Carefully lift the sending unit out of the tank.
  3. Inspect the Sending Unit:

    • Check the float arm for any obstructions or damage.
    • Measure resistance with a multimeter to confirm it changes smoothly as you move the float.
  4. Replace if Necessary:

    • If damaged, replace the fuel sending unit with a new one.
    • Reinstall the sending unit by reversing the removal steps.
3. Inspect Instrument Cluster
  1. Remove Instrument Cluster:
