Good old P0031

P0031 - O2 Sensor Heater control circuit low

What should I do? Is there an easy fix? Is this a pretty common problem? Where is the sensor?

Did it say bank 1 sensor 1 or sensor 2? 1 is on the manifold 2 is in between the cats.

bank 1 sensor 1... just got back from the mechanic. He told me it isn't very high priority but I still want to fix it. I have no idea which one to buy though?

That's the one on the manifold. I have that code every once in a while to now, I need to replace it too.

The mechanic told me a wire was loose on the original O2 sensor, and he fixed it. But he told me the exhaust manifold might be cracked or leaking... wtf my car has under 50k miles and I don't drive like a ricer. MSP's are lemons.

I just got this code after installing a new o2 sensor on my manifold...before the sensor was reading no activity...now its brand new and I get a code...plus I am trying to go in for inspection and I dont want this to throw a CEL after the drive cycle completes (I just cleared my codes after the install)
