What are stock o2 sensor readings for all banks on 06 Auto DE? Need help asap.

Car had p2a00 code, basically looked like a lazy b1s1 stuck around .3v .. put new oe denso sensor in, runs better, faster, but after 50 miles code came back. Sensor is also around .3 this time around but seems like it jumps around more and reads more values than the last sensor. b2s1 reads ~.5v at idle.

the other 3 sensors seem to be acting normal via live data. did put an aftermarket sensor in b1s2 but would that cause the upstream sensor to read bad? Doesn't make sense... b1s1 seems to be the only one out of whack. bank 1 fuel issues? Exhaust leak? Will be getting b1s1 swapped out with b2s1 tomorrow to see if the issue follows. Also, maybe my little code reader isn't capable of reading correctly, or nissan could be the reason for the diff voltages (think i read somewhere that this is a possibility, but it wasn't listed for my year car)

Any help is appreciated. Thanks.

 

Update: Gas milege went down to 5-8mpg. The code didn't pop back up at 50 miles exactly like the last two times. I'm thinking it might be harness related.

 

 

This is 06 DE Auto... Not HR

 

Some weird **** going on on this site. I posted this vid to a thread where someone was having an issue with low oil pressure. Not sure how it was posted here.

 

That is very weird! I think i might have experienced some glitches as well while recently revisiting the forums (since a long time) via firefox.

 

I wish I could give you some advice, other than what some might consider common knowledge regarding sensors which is to always use original equipment. I bought new upstream o2's a couple years back and never had an issue.

 

Yes i did replace with the oem denso sensor. i think my HFCs might be cracked around the top or something that i cant see from the bottom
