Hello and welcome to justanswer.com
That code is for bank 2 sensor one.
This is the top or upstream sensor on the driver side exhaust.
Richard, can I see this o2 sensor or do I have to remove something to access it for removal?
LOOSEN AND REMOVE THE TORX BOLT SECURING THE COOLANT TANK THEN MOVE THAT OUT OF THE WAY. oN SOME THERE IS A HEAT SHEILD THAT BOLTS TO THE CAT CONVERTER WHICH ALSO MAY NEED TO BE REMOVED.
