Go to your local automobile repair shop and have them hook up a handheld computer, it will read you the code and tell you what the problem is. You can also delete the code and it won't come back up for another couple hundred miles, depending on the car. do it yourself alternative: I have a 1991 Previa. I believe the 92 has the same layout. Turn all accessories off. Engine off. Under the drivers seat is a small plastic box. Pop the lid. With a wire, paperclip, etc, place it in the connector pins TE1 and E1. Turn engine key to "ON", but do not start engine. The check engine light will blink out the code (like telegraph code). I don't have the codes handy, but see for example the Chilton or Haynes manual, or do a web search (good luck).
under driver seat where the engine is located, you'll see the oil dipstick. It's yellow in color.
check the Distributor.
get a haynes manual at a library
I would advise you to check out the Previa site on yahoo. It is an excellent site. Check this site it out http://tarago.blogspot.com/ , it helped a lot.
You will need to go to a repair shop and have them scan for codes. That will tell them the problem and when it is repaired they can reset the light.

The check engine light comes on and stays on when there is a problem with the emissions systems. You need to have the ECU scanned with an OBD2 scanner. This will retrieve the code that has been set and tell you what part of the system is being effected. It will not necessarily tell you what part is defective.
