Code P0153 Bank 2 sensor 1 slow response.
 

Could some of you more exp. techs please tell me what would cause this code
P0153. I believe an 02 sensor is one of the possibilities. What else?

thanks
your help would be most appreciated

P0153
Upstream oxygen sensor circuit slow response bank 2

would be oxygen sensor just before the catalytic converter

Thanks STL I replaced the O2 sensor this weekend and reset the code. Lets see if thats the fix.

I was just going off the info provided in the Chilton manual it was pretty vague as to any other solutions
