P0036 code need help

So the other day I seen a ground hog go under my car. I went out to start it to go get it inspected now I have a cel light and the code is p0036 I have reset it multiple times. Checked the wiring on the post 02 sensor and can't find anything.. this is really frustrating since today is my last valid day for my inspection.

I'm confused...
p0036 is a heater circuit code, nothing to do with the post CAT o2 sensor?

Code P0036 is a generic diagnostic trouble code (DTC) that's set when there's a potential fault in the downstream oxygen (O2) sensor's heater circuit. ... The faster the heated oxygen sensor reaches that temperature, the faster the sensor will start sending an accurate signal.

Replace the 02 sensor, nothing to do with the ground hog.
Are you running premium fuel?

I always run premium 93. What's the best/cheapest 02 sensor to go with??

I have an R50 non blower and found these on Amazon;
Amazon Amazon

I reset my ECU and filled my tank with premium and the 02 light went out on mine. I just got the car so I have no idea what fuel it had in it, I also just replaced the CAT so you might not get the same results but it worked on mine.

I bought 2 Magneti Marelli's for my R53 JCW, they were about 30 euros a piece here in NL. I had a VEMO once, but that one gave errors after a very short time, never again for me.

Don't waste your money with non OEM oxygen sensors sensors trust me, I burnt one out every 2 months until I got sick of it and finally bought an OEM1 and it's now lasted past the 2 months finally .

I guess my code library wasn't wrong, it was just incomplete...
Oops.
