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.
What else can I help you with?

Battery made check engine light come on?
Only the computer can tell what made your check engine light come on. It could be your battery. If your battery is bad, replace it and see if that solves the problem. If it does not, then you will have to connect your car to the computer and find out why the check engine light came on.
Will check engine light go off after I drive awhile since it came on after the battery was changed?
Replacing the battery should not have triggered the check engine light. The check engine light comes on when there is a problem with the emission system. Saying that, I would drive it for a while to see if the light does go out. If the light does not go out have the ECU scanned to retrieve the trouble code. Then use this code to diagnose the problem.

What should you do if the diagnostic for a '97 Nissan has error code 446 the gas cap was replaced and the check engine light came back on?
Did you reset the Check Engine light? If not, reset by disconnecting the negative battery cable for a couple of minutes. This will erase the computer. Reconnect the battery cable and if everything is OK, the Check Engine light should be off.

Why Battery light came on and then car died?
Most likely the alt. quit. The battery ran out of charge. Charge the battery, start the engine, and check volts on the battery, anything less than 14 volts, like 12.3 or so, check wires, and most likely change the alt.
How do you find the solution for no power to crank engine not even a click with a fully charged battery I closed and reopened drivers door and the interior light came on tried engine and it cranked?
