Solution

1. Preparation

Gather tools and parts before starting the repair.
Disconnect the battery to ensure safety while working on the fuel system.

2. Access Fuel Level Sensor

Lift the vehicle using a jack and secure it on jack stands.
Remove the fuel tank shield (if equipped) by unscrewing the bolts with a socket set.
Detach the fuel lines using a fuel line disconnect tool, being cautious of fuel spillage.

3. Remove and Inspect Fuel Level Sensor

Locate the fuel level sensor at the top of the fuel tank.
Unplug the wiring harness from the fuel level sensor.
Remove the sensor by unscrewing any retaining screws or clips and gently lift it out of the tank.
Inspect the sensor for any visible damage or blockage.

4. Replace or Repair Component

If the sensor is faulty, install a new fuel level sensor, ensuring proper alignment and secure attachment.
If wiring damage is found, repair or replace the wiring harness as necessary.
Reconnect the wiring harness to the new or repaired sensor.

5. Reassemble Components

Reinstall the fuel lines ensuring they are secure and leak-free.
Replace the fuel tank shield, if removed, and bolt it back into place.
Lower the vehicle back to the ground and reconnect the battery.
