Could be. try adding a spacer to the sensor to move it slightly out of the exhaust stream and see if that fixes it or you could have just got a bad sensor?. it should throw at cat efficiency code not an 02 code if the cat is failing. an 18mm sparkplug antifouler makes a good spacer but you may have to drill the center out for the sensor to fit. what is the code and definition that you are getting?

Probably either a bad sensor or the wiring
