2008 VW jetta 2.5 (o2s11 ma -127.0)

So long story short I have a misfire on cylinder 1. Last year I ran over a rock and it cut the wires to o2s11 (the o2 sensor after the cat.) I spliced them together but it had blown fuse. I replaced fuse and thought it was fine. Now I scan with obd2 and I see o2s11 ma -127.0 it doesn't seem to move from there. I unplug the sensor and it still says -127ma is that a normal reading?
