I pulled this code (0413) and used the link on the sticky to find out what this meant. It didn't even have 13 as an option for the 2nd number.

Then I used the 2nd post in the sticky and it's listed there. What's up?? I searched the web with the code and got "Front Heated Oxygen Sensor. Bank 2"

This sound right? Is this something that needs to be fixed asap or can I give it a week or two?

 

You got the right code and diagnosis. You don't need to fix it right now but your fuel economy will suffer a bit as will overall performance. Straight out of my Haynes book, 0413 is "Upstream oxygen sensor circuit slow response fault (left bank)" if that helps any more.

just replace your front O2 sensor.
