Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Access Fuel Level Sender

Tools Required: Socket set, ratchet, torque wrench
Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the fuel tank access cover located under the rear seat or in the trunk area.
3. Disconnect the fuel pump wiring harness to access the fuel level sender.

3. Inspect and Replace Fuel Level Sender

Tools Required: Multimeter, replacement fuel level sender
Sub-steps:
1. Remove the fuel level sender from the tank by unscrewing the retaining ring.
2. Measure the resistance of the sender using a multimeter:
  - If resistance varies with arm movement, sender is functional; if not, replace it.
3. Install the new fuel level sender in the tank and secure it with the retaining ring.
4. Reconnect the fuel pump wiring harness.
