how to fix the Honda CR-V Sixth Generation (2023-present) fuel gauge not working

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Access Fuel Level Sending Unit

• Tools Required: Socket set, screwdrivers, safety glasses, gloves.
• Remove the rear seat or access panel to reach the fuel tank.
• Disconnect any fasteners and lift out the access cover to expose the fuel pump and sending unit.

3. Inspect and Test Sending Unit

• Tools Required: Multimeter.
• Carefully disconnect the electrical connector from the fuel level sending unit.
• Measure the resistance across the sending unit terminals. A typical range is 0 to 90 ohms when the tank is full.
• If the resistance is outside this range, replace the fuel level sending unit.

4. Replacing the Sending Unit (if necessary)

• Remove the old fuel level sending unit by unscrewing it from the tank.
• Install the new sending unit, ensuring it is seated properly and secure.
• Reconnect the electrical connector and any hoses or wiring removed during access.

5. Reassemble and Test

• Replace the access cover and reinstall the rear seat or access panel.
• Reconnect the battery and start the vehicle.
• Check the fuel gauge operation by monitoring it while adding fuel to the tank.
