There could be a wiring issue with the vehicle speed sensor from the computer to the speed sensor pigtail. If the wiring is good, then the PCM may not correctly configured for the actual tire size on the vehicle. If you need further assistance with your engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.
