Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The speedometer may stop functioning with code P0722 stored in the powertrain control module (PCM). This may be caused by a worn speedometer gear due to coolant contamination of the transmission fluid. If contamination is found the radiator is most likely at fault. The transmission should also be thoroughly inspected and repaired or replaced as required.
The turn signal switch may fail causing the turn signals to stop working.
