Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent any electrical shorts.
Ensure the vehicle is parked on a level surface and the fuel tank is sufficiently low to avoid spills.

2. Inspect Wiring and Connections

Locate the fuel level sensor connector, typically found on top of the fuel tank.
Visually inspect the connector and wiring for signs of wear, fraying, or corrosion.
If damaged, repair or replace the wiring and connector as necessary.

3. Replace Fuel Level Sensor

Tools Required: Socket set, screwdriver set, fuel line disconnect tool (if applicable).
Remove the fuel tank if necessary (refer to manufacturer service manual for specific instructions).
Disconnect the fuel pump wiring harness and fuel lines using a fuel line disconnect tool.
Remove the retaining ring holding the fuel level sensor in place.
Carefully extract the fuel level sensor from the fuel tank.
Install the new fuel level sensor by reversing the removal steps, ensuring it is seated properly and the retaining ring is secured.

4. Reconnect Battery and Test

Reconnect the battery terminals securely.
Turn the ignition to the "On" position without starting the engine to allow the fuel system to pressurize.
Check for leaks around the fuel tank and connections.
Start the vehicle and observe the fuel gauge for proper function and accuracy.
