Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,The wrench light come on when the computer system sees a system fault and when this happens the computer will set and store a fault code and or codes, in order to determine what is failing you are going to need to have the computer system scanned and the fault codes retrieved. If you can get the scan done and the codes I can help you determine the cause. Most auto part stores will run a scan for you at no charge as well.
