Oxygen Sensor Replacement

[CoffeyLover]

So today its a simple question. I pulled the codes off my babyy and got this:

 

Current Fault Log

------------------

P0134: O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)

P0154: O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

P0174: System too Lean (Bank 2)

P0758: Shift Solenoid "B" Electrical

 

I know I know, P0758. S***!!!!!! Anyways, can someone tell me where those two sensors are so I can replace them? I already ordered the parts.

 

Thanks!

Bank 1 sensor 1 is driver upstream before cat) , and bank2 sensor 1 is passanger upstream. Bank 2 is after cats. Didn't you do a motor swap...it's a little wierd to see no activity detected, you did plug the o2's back in right, or maybe damage wires?

Its possible I guess. Ill check after work today and see, I already have new ones but i would love to return them

If bank two is after cats wouldn't bank 2 sensor 1 be driver side downstream? I think you contradicted yourself...

Bank 1=bank with #1 cyl. On GM that means LH, drivers side.

Sensor 1=sensor BEFORE cat.

Sensor 2=sensor AFTER cat.

You using a 4l60 behind that 6.0 or something? I think it's too weird that both main o2's are acting up at the same time myself.

Yes sir there is the stock 4l60e trans in it as of now. But that shouldn't have anything to do with the O2 sensors I wouldn't think...

It doesn't, just asking.

Oh ok. And yeah I know the tranny is on it's way out haha. I'm gonna put a Monster Transmissions SS 4l60e in it when this one dies. I'm just trying to see how many miles I can get out of it. 150k+ so far!

I did contradict myself, meant to say sensor 2 is after cats and not bank 2 is after cats. My bad
