Hello and thank you for using JustAnswer. My name is \*\*\*\*\* \*\*\*\*\* I will do my best to assist you.. I help many customers, so sometimes my replies are delayed, I will respond once available. During this conversation you will be given an automated offer for a phone call. You may accept or decline that offer.I don’t personally offer this service so if you take this another tech may call. This light will come on when the computer sees a problem that affects the performance of the engine or [transmission](/topics-transmission-ford/). There are many problems that can fail that will trigger this. It could be a faulty sensor, wiring issue, module fault, engine malfunction, etc. To see what specifically is causing the light to come on the vehicle will need to be tested with a scan tool that connects to the vehicle. This test will provide a trouble code that describes what specific system is having the problem. If you can have the vehicle scanned and can give me the code, I will be able to tell you specifically what is wrong with it. If you do not have a scan tool then you can bring your vehicle to any auto part store and they will scan it for free and give you the trouble code. I would do this ASAP so that we can determine what the problem is and keep any other problems from happening.
