Code P2198 O2 Sensor Signal Stuck Rich - Bank 2, Sensor 1

Got a check engine light 2 days ago and went out today to purchase a reader which I will probably return within 30 days. The reader pulls code P2198 O2 Sensor Signal Stuck Rich - Bank 2, Sensor 1. Did some googling but I am coming up short with what exactly this is. Some people were saying that a custom exhaust can set off this code? My car has Pypes true dual setup and is a 2005 V6, It runs the exact same as before, and gas consumption seems normal. Just the check engine light is on. Any recommendations? Should I clear it and see if it comes back or bring it in to my mechanic. Thanks!

Yep! Clear that CEL Code and see if it comes back.....Then you can start to worry about replacing it...But since its a "Signal Stuck Rich" Code, I would certainly verify to see if its just a Glitch that was thrown when the car was in "Open Loop" (Cold Startup) or if indeed the sensor needs replacing......
