hi everyone. recently i had a short in my o2 sensor connector for b1s1 which was fixed by my mechanic. however ever since i have been getting this p1083 code and the b1s1 voltage flatlining at ~0.33V when driving

i just then checked with key on engine off and the voltage is at 1.275V whereas all other sensors are at 0.43V

I have already attempted replacing the oxygen sensor and it has not done anything.

Any help is greatly appreciated.
