Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,The wrench light comes on when the computer system sees a system fault and when this happens the computer will detect it and set and store a fault code. In order to know what is failing you are going to need to start first with having the system scanned and the fault code and or codes retrieved. Most Auto part stores will do this can for you at no charge. If you can get this done and post back with them I can direct you with the correct repair. This is very likely something you can fix your self.
