Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety during repairs.
  • Remove the rear seat or trunk panel to access the fuel pump assembly.
2. Remove Fuel Pump Assembly
  • Sub-steps:
    1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
    2. Disconnect the wiring harness from the fuel pump assembly.
    3. Remove the fuel lines from the assembly using a line removal tool.
    4. Unscrew the fuel pump assembly retaining ring and carefully lift the assembly out of the tank.
3. Inspect and Replace Fuel Level Sensor
  • Sub-steps:
    1. Remove the fuel level sensor from the fuel pump assembly.
    2. Use a multimeter to test the sensor resistance; it should vary smoothly as you move the float.
    3. If the sensor is faulty, replace it with a new one (ensure it’s compatible with the RAV4 XA40).
    4. Reassemble the fuel pump assembly, ensuring all seals are intact.
4. Reinstall Fuel Pump Assembly
  • Sub-steps:
    1. Place the fuel pump assembly back into the tank and secure it with the retaining ring.
    2. Reconnect the fuel lines and wiring harness to the fuel pump assembly.
    3. Reconnect the fuel pump fuse and reconnect the negative battery terminal.
