Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery.

2. Access Fuel Sender Unit

Remove the rear seat or access panel to reach the fuel tank access point.
Disconnect the fuel pump electrical connector and remove any retaining screws or bolts.

3. Remove and Test Fuel Sender Unit

Carefully lift the fuel sender unit from the tank.
Use a multimeter to measure the resistance of the sender unit while moving the float arm. The resistance should vary smoothly from empty to full.
If the resistance is not within specifications, replace the fuel sender unit.

4. Inspect and Repair Wiring

Examine the wiring and connectors for corrosion or damage.
Repair or replace any damaged connectors or wires as needed.
Ensure all connectors are securely attached.

5. Reassemble Components

Reinstall the fuel sender unit into the tank.
Secure it with screws or bolts and reconnect the fuel pump electrical connector.
Replace the access panel or rear seat.

6. Final Check

Reconnect the negative battery terminal.
Start the vehicle and check the fuel gauge operation.
