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.

MSR

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

SUB-OXYGEN SENSOR CIRCUIT OR SUB-OXYGEN SENSOR HEATER CIRCUIT

--SUB OXYGEN SENSOR/HEATER/CIRCUIT

--ECU
so o2 sensor then. change the one before or after the cat?

MSR

after

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