Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Remove any necessary trim or panels to access the fuel tank.

2. Inspect Fuel Gauge Sender Unit

Tools Required: Socket set, screwdrivers.
Remove the fuel tank access cover if applicable.
Disconnect the wiring harness from the fuel sender unit.
Inspect the wiring for any signs of wear or damage.
If damaged, repair or replace the wiring.

3. Replace Fuel Sender Unit (if necessary)

Tools Required: Socket set, fuel line wrench.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the negative battery terminal.
Remove the fuel tank, if required, to access the sender unit.
Unfasten the fuel sender unit from the tank and carefully lift it out.
Install the new fuel sender unit by reversing the removal steps and ensuring proper sealing.

4. Check and Reinstall Fuel Gauge

Tools Required: Multimeter.
Reconnect the fuel gauge wiring and check the gauge operation by turning the ignition on without starting the engine.
If the gauge does not respond, consider replacing the gauge itself.
Carefully reinstall any panels or trim removed during the process.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check the fuel gauge for proper operation.
Test drive the vehicle to ensure accurate fuel level readings.
