Try this link:http://www.off-road.com/toyota/tech/codes/index.html

There aren't any codes that aren't covered somewhere.

I hope you have a California vehicle. A code 27 is the sub oxygen sensor which is only on CA vehicles. It's the oxygen sensor behind the cat.

sounds like your after cat o2 heater went bad. Disconnect the sensor and check resistance across the two similar color wires usually white or black little or no resistance good, open bad

Nope. But, you could always put a piece of tape or groovy sticker over it.
