The code log below is from after i changed to O2 Sensors to the NTK OEM ones, Odd it is showing P0057 and P0037 now?! Heater Control Circuit Low. Does this mean those O2 sensors are bad that I just replaced?

I only received P0031 P0051 and P0150 before i swapped out the NTK Sensors. Crazy.

I will put the old stock ones back in. See if i can get it back to only P0031 P0051 and P0150. IF this is the case, do i need to change both upstream O2 sensors? Are they Shot?
