It means the computer has detected a problem with the emissions system. Make sure your gas cap is tight. If that is not the problem, then you need to have the computer scanned for a fault code. This code you give you and idea where to look. Auto Zone & Advance Auto Parts will do a free scan in most states. The ZX2's are notorious for having temprature sending unit problems...a quick fix to get the light to go off is to make sure the radiator is full first....then if that is ok disconnect the RED or POSITIVE battery terminal for about 5 - 10 minutes. This resets the computer. You'll have to reprogram your radio and clock but the CES light will be out. If it comes back on then have it checked like above.
