I just had my car serviced because the “check engine light” came on and shortly after the repair the light is on again. Did my repair shop make a mistake?
Maybe – maybe not. Because the check engine light/service engine soon light illuminates for many different reasons (I.E. A bad sensor, a bad computer, a vacuum leak, a bad fuel pump, a bad spark plug, a plugged fuel filter, a broken, pinched or disconnected wire, a loose gas cap, or engine overheating, etc,). The vehicle must be rechecked by a trained and experienced technician to determine the actual cause. Make sure your service advisor provides you a printout of the “codes” or other findings that indicated the need for the associated repairs when the check engine light came on. This way you will know, if the light comes on again, if it is related to the previous repair or is it a completely new problem with the vehicle.
