SERVICE ENGINE SOON LIGHT

2000 Ford Expedition

Computer problem

How do get the service engine soon light to go off?

Also, why do I not have a check engine light?

Hi: The check engine light is set by the computer when it recognizes a problem with an electrical item such as a sensor or a misfire. To turn it off, you need a scan tool.

What I recommend is to take the car to a nationally recignized parts store and have them scan it and turn the light off for you. Most will do it for free. But keep in mind, the light is on for a reason, and if the problem isn't repaired, the light will eventually come back on for you.

Let me know what you find.
