Think of taking your temperature. Say it's 101. Your heat sensor – the thermometer – tells you that your temperature is out of the normal range. But it doesn't tell you why you have a fever. Is it the flu or a sinus infection? You need more information; more tests. When your engine management system logs a problem and illuminates the check engine light, we will plug in a scanner, download the trouble codes and go to work tracing the cause of the problem.
If your check engine light is flashing it means that the problem could lead to serious damage. You should get to the service center as soon as possible to get the problem solved. If it's on but not flashing, you have some time to get in at your convenience.Learn more at NAPAautocare.com/preventative-maintenence/
