Need new O2 sensor and not sure what to get (bank 1 sensor 1)
I have had my CEL on for a while now and my neighbor ran the code and it was for an O2 sensor, specifically the bank 1 sensor 1.
I've been searching google and I am confused as to which one this actually is and what part I need to get. I am not sure if it is upstream or downstream, front or rear, right or left.
My neighbor is a part owner of a car shop and he said he can get me the part for $148 but I wanted to search and see if I could find one cheaper online somewhere, but I am not sure which one to actually get. I searched amazon but a bunch of results came up and I'm just not sure which one matches the one I need.
Can anyone point me to which one the bank 1 sensor 1 actually is? Also, is $148 for the OEM part a good price? If so I'll just tell him to get it for me.
Thanks!

Bank one is the Right (passenger) side, sensor one is upstream.
I bought one of these to replace. Look for the Denso part# 234-9135. $118, mine shipped was $129.

Mine just failed recently... lol. The passenger side O2 sensor is super easy to replace - if you look down past the intakes you can actually see it. The driver side (the one that failed for me)... isn't quite so easy.

because I’m finding sensors of the same kind but for different prices and there’s a big difference in price

Upstream, (before the cats) are roughly double the price. And no, they will not all be the same length. I believe the downstreams have to be longer because they are placed further from the engine bay.

I have code P2A00, P2A03 And thought it was normal due to after me getting TestPipes installed! The car has been running great no issues but instill got the codes so they affect daily driving?
