My service engine soon light came on a day two ago, I have driven the car about 20 miles since it came on. Today, the light just went out. The vehicle is running good. What would cause the light to come on, and why would it just go out on its own?
You'll need to take the car to a mechanic who will put the diagnostics computer on the car (about $50 around here) find out what is the malfunction .repair it and then the light will go out, or he'll reset it. HTH, Chuck
You can reset it by hooking up your jumper cables to another car and then starting the other car but not starting yours. Then go to the back and reset the speakers and that usually does the trick.
