why is my Toyota Camry's fuel gauge not working correctly

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Access the Fuel Sender Unit

• Remove the rear seat or access panel, depending on the Camry model year.
• Locate and unbolt the fuel pump assembly from the fuel tank.

3. Inspect and Test the Fuel Sender Unit

• Carefully lift the fuel pump assembly from the tank.
• Use a multimeter to measure the resistance of the fuel level sender. It should change smoothly as the float moves.
• If the resistance is inconsistent or out of spec, replace the sender unit.

4. Check and Repair Wiring

• Inspect the wiring harness connected to the fuel sender for frays or breaks.
• Repair or replace any damaged sections of the wiring.

5. Reassemble and Test

• Reinstall the fuel pump assembly and secure it to the fuel tank.
• Reconnect the negative battery terminal.
• Start the vehicle and check the fuel gauge for proper operation.
