If the wrench light has illuminated in Your 2008 Ford Fusion, it means that there is an issue with the throttle body or related component. This vehicle is equipped with an electronic throttle body. They are known to have issues sending false signals to the PCM when sludge builds up. The wrench light triggers fault codes, which the mechanic is able to retrieve from the computer memory to diagnose the problem. It's usually caused by low voltage in the system or abnormal temperatures between the cylinder and block head. It can also signify a faulty oil cooler. In some cases, the electronic computer module is known to glitch in this vehicle and the light goes off on its own. However, it's always a good idea to have it checked, just in case. If there is a serious problem, Your vehicle may go into limp mode.

The 2008 Ford Fusion wrench light is about the Throttle Control/Transmission. The light illuminates when a powertrain or an AWD fault has been detected. Contact your authorized dealer as soon as possible.
