The service engine soon light came on. so I took it to the local mechanic. They checked the code and told me I needed a fan clutch. So i replaced that. The very next day after maybe 30 miles the service engine soon light came back on. I took it back to the mechanic and had the code read again. This time they said that the temperature sensor needed replaced. which i had them do. The next day on my way to work. Again less than 30 miles the service engine soon light came back on. What gives. I'm down 500 bucks in a week and the damn light is still on.
