How do you reset the check engine light on a 2000 Toyota tacoma?

I don't know about the 2000 year model directly but the 1996 is similar I am sure.

To reset the "check engine" light, find the EFI fuse (probably under the hood in the fusebox on the driver's side) and with the engine off, remove it for one minute minimum. Replace the fuse and the "check engine" light should be reset.
