I am sorry but no, there are different codes some are P codes, some are B codes, and there are other ones, OBD 1 (84-96) systems could flash the check eng lite and give you codes, but they were just two numbers like 12. A typical OBD 2 code is like this P1546, this is a emission code. Kragen auto or any of the chain auto parts stores will read the codes for free.

Hey alanacheson,
The spark plugs are underneath that cover on top of the engine (should say VVTi on the cover).
Just take that cover off, and then you will see the four ignition coils. Take off the four ignition coils (with igniters), and you will see the four relatively long holes underneath, and the spark plugs are at the bottom of those holes. You will need a good spark plug socket (preferably a thin wall socket) and a 6" or 12" extension. This is actually a very easy job, and can be completed in less than an hour.
Hope this helps.
