Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and support it with jack stands if needed.

2. Access Fuel Level Sensor

Remove the rear seat cushion or access panel to reach the fuel pump assembly.
Disconnect the fuel pump wiring harness and fuel lines carefully to avoid fuel spillage.
Use a socket set to remove the retaining ring and lift the fuel pump assembly out of the tank.

3. Inspect and Replace Fuel Level Sensor

Remove the fuel level sensor from the pump assembly by unscrewing it or unclipping it as necessary.
Inspect the sensor for signs of wear, damage, or corrosion.
If faulty, replace the fuel level sensor with a new one (ensure it’s compatible with the 2023 Honda CR-V).
Reinstall the sensor into the pump assembly, ensuring it's secured properly.

4. Reassemble Components

Reinstall the fuel pump assembly back into the fuel tank and secure it with the retaining ring.
Reconnect the fuel lines and wiring harness, ensuring a tight fit without leaks.
Reinstall the access panel or rear seat cushion as applicable.

5. Testing

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position (do not start) to prime the fuel system, then check for leaks.
Start the vehicle and monitor the fuel gauge for accurate readings.
