O2 sensors voltage low bank1 rear left

[Durango]

That was the reading on the machine that I was given today and the mechanic tells me It could be wiring related..... Have you heard of that before?
Is an NGK model o2 sensor good quality?



Expensive at $142.00 Cnd. I hope that they don't all let go. Are they hard to change they are charging me 1 hour labour if everything goes well It seems pretty darn easy to me to change looking at it anyway.

bosch 50 bucks work fine on both primary banks for me. If you have headers check to make sure you didn't burn a wire lead to the O2's
