The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
May have to change oil.
You can disconnect the negative battery cable, wait a couple minutes then reconnect the cable. This will clear the codes and reset the check engine light but, if the reason the light came on isn't fixed the light will come back on soon.
