How do you repair fuel sensor heater circuit reponse?

To repair a fuel sensor heater circuit response, first, diagnose the issue by checking for any fault codes using an OBD-II scanner. Inspect the wiring and connectors for damage, corrosion, or loose connections, and repair or replace as necessary. If the fuel sensor heater itself is faulty, replace the sensor. Finally, reset the vehicle's computer and verify that the issue is resolved by conducting a test drive and checking for any new fault codes.
