well, imnot sure. in the service manuals, there are diff types of codes, and the corresponding problems. code 21 can have several meanings.
for the O2 sensor, i would say that you should check the resistance or voltage that they are producing with a voltememter.
but then again, i havent ever messed with mine except takin it off, and puttin it back on during a catback install.
how is your fuel efficiency? that will tell you for sure if it is your 02 sensor shittin out on ya.

well, it first came up when I took the turbo off. And at that point I took the O2 sensor on and off 5/6 times before. how much are the $30-$60 rite?
