Resent?? Trust me.. it's easy.. we all resent the check engine light.. lol!!
However.. asumming you meant "reSET" the light.. you need to use a trouble code reader that has the capability to "erase" trouble codes once it reads them. You can purchase these online or at most any auto parts store starting at about $69.00 up to $400.00. For a 2000 model Celica, you will need one that is "OBD2"(I recommend the Innova 3100 ... $88.00 on Amazon.com).
BE ADVISED... simply erasing the code and resetting the light does NOT fix the problem of why it came on in the first place and there is a 99.99% chance that the light will come back on within a few miles of driving until the cause of the light coming on is resolved.
Hope this helped.

Like many engine and diagnostic parts of the 1990 Toyota Celica, the tachometer needs the assistance of a fuse to operate correctly. Check the fuse box for a blown fuse for this instrument.
Check the fuse!
You may want to check your catilick converter or your crankshaft positioning sensor.

It is probably your EGR valve causing the check engine light. I recently bought a used 1997 Toyota Celica and had this exact problem. The new valve cost approximately $85 and fixed the problem right away.
there is a reservoir on the passenger side of the engine bay, two levels are mark'd on it... hot level and cold level, depending on the engine temperature.
check the CV joints or the transmission is slipping
You might have to much oil in the engine. Check oil. Clean spark plugs. (remove and use sand paper to clean)
Same place you check it.
Could be a vacuum leak - check all lines and connectors udner hood and under the dash. Might be the check valve on the power brake booster.
you will need to take it to a shop and have them delete the code that your car has set. also if you have them delete it you can have them tell you what the problem was and you can fix it so that it does not come back on
