A/f sensor honda crv calls it the same thing most people call it an o2 sensor but on some models they are wrong.
the a/f sensor has four wires two are the a/f portion two are the heater curcuit , this is internal to the sensor and does what it says heats the sensor on start up till the exhaust takes over then heat circuit switches off.. i know the crv one is like 230 bucks here in ontairio from dealer . you can get aftermarket o2's but not heard of a/f avail. try your local auto wreckers for one .. the scan that told you the heater circuit was bad should have said b1 s1 or b2 s2 type thing.. this refers to the location of the sensor bank one sensor one refers to odd cyl side of engine sensor above catalitic cnverter s2 refers to behind cat conv
ect... special socket may be needed to remove (accomodates wires) sum times 7/8 wrech will work do it cold or you may strip the threads coming out!!

their is a plastic cover on the drivers side under the car. you will have to take 4, 10mm bolts off and then you push the green clips and pull a same time and the filtler will come off

look at the exhaust pipe and manifold you will see 1 sensor at the header and the other before or after the cat, depending on if you have to exhaust pipes.

no you need an a/f sensor if the code is for a bank one it is located on the exhaust manifold on the back of the engine compartment vise versa if it is for bank 2

Welcome to FixYa. I'll be glad to help you out.
Code P-1150 indicates an Air-Fuel sensor range/performance issue.
The air fuel sensor is similar to an oxygen sensor, but it does a different job.
Without in-depth analysis on a scan tool that can read the output of the A/F sensor, it is hard to tell you exactly what is happening, but prior experience indicates that you probably need to replace the A/F sensor.
You would do well to purchase a genuine Toyota A/F sensor, as the cheaper 'aftermarket' units do not perform well; your check engine light may remain on after you replace the sensor with an aftermarket
Thanks for choosing FixYa for advice.
