Hi,

I have a 1998 Chevy C1500 (5.7 liter) with the Check Engine Light on. My scanner is displaying code P0160: Generic O2 Sensor CKT No activity (Bank 2 Senor 2). My mechanic replaced the O2 sensor. My senor gives my the following monitor information: CAT NOT RDY; KCM N/A; EVAP NOT RDY; Z AIR N/A; A/C N/A; O25 NOT RDY; HO25 NOT RDY. What's my next action? I'd like to fix this myself. He suggested that I may need a new catalytic converter.

Thanks.
