Weird code since MS
 

So I can clear this code, but every now and then it still comes back. It is code P1170. It only did this since MS, and when I go into about 5psi of boost. I think it's some kind of manufacturers code, but what is it?

P1170 - (HO2S 11) Signal remained unchanged for more than 20 seconds after closed loop.


That's from ARRC.

Thanks. I figured it wasn't a error that meant anything more than to be a pain in the ass...
