Hello, thank you for writing in. Considering the age and the mileage on the vehicle, it is not impossible for a few of these components to be going out at once. If the check engine light remains on, you will want to pull any existing codes from the vehicle’s computer. You can then reset the codes and drive the car like normal. If the light resets and the codes are the same, you can be sure there is another problem with the system setting the code. Further action can be taken from there. For more help at that point, contact our service department to schedule an appointment.
