When to Call a Professional

Call a professional mechanic if the fuel temperature sensor is located inside the fuel tank (requiring tank removal), if multiple fuel system codes are present, or if you're not comfortable working with electrical components. Also seek professional help if the problem persists after sensor replacement, as this may indicate ECM issues.
