The first issue can be solved by replacing the camshaft position sensor. In the unlikely situation that it does not fix it, remember you have to clear code, then you may have to check circuit and I can give you wiring diagram.

The oxygen sensor heater is probably just the O2 sensor in need of replacement as tose are self heating O2 sensors.

I am attaching entire set of engine wiring harness for 1.8L. On diagram 4of 4 there are two camshaft snensors, one on top of diagram one on bottom, that are reffered to as oil control sensors as well. I do not have much information on why they are called that. But, there is one for each sie of cam and it gives positon description in diagram.
As for the O2 sensor, it will be in echaust tract near converter.

2012? 12k? These are warranty items. You should not be responsible for these rep[airs.

No, the one you are referring to is the variable valve timing solenoid. Different sensors, different functions.
