Can't seem to find out what this code means?

I have two codes coming up on the GP-GT!

P0137 - circuit low voltage bank 1 sensor 2

P0141 - Heater circuit bank 1 sensor 2

Just bought the car and they guy said he just did the intake manifold gasket so maybe he didn't get the codes cleared? Any help and clarification here would be greatly appreciated. :cheers:
 


I've already cleared the codes with my Diabosport but I'm wondering why there was no ses lights on the dash? Thanks for any ideas what these mean. :)
 
hp tuners lists it as "ho2s circuit low vlotage bank one" and "ho2s cicuit ext ext"....looking like o2 sensor to me. some codes wont set the light on at all and some will take the event happening twice to set the light. thats why. with hp tuners u can even modify this and make any code turn the light on or make them not depending on your preference.
 
Seeing that you have a code for the heater circuit as well, I would say the o2s. The code is set for the circuit, which can be the pcm, o2s, or anything inbetween. Without a full diagnosis my guess goes to the o2s.
 
Bank 1 sensor 2 is the rear O2 sensor behind the cat. What the codes are telling you is that either the heating circuit in the sensor is bad or the wirng to the O2 has an issue.

Usually this is a bad O2, however one should not rule out basic visual checks of the wiring first.
