Bank 1 Sensor 2 - will this fit
It says it fits my year but I get so confused trying to figure which O2 sensor is which
http://www.ebay.com/itm/NEW-DIRECT-F...ht_3787wt_1304 |
Isn't that sensor for bank 1 sensor 1? :scratch: Not 100% sure.

Arent the 2 front ones interchangable?

Huh, wonder why they are showing the same part number then :gotme: that's the only reason I thought they were interchangable.
|
so what do i need to look for when searching on ebay, rear left?
|
search front heated oxygen sensor. go to rock auto and get a decent one. Its kinda importante. As far as interchangeability the up stream is diff from the downstream. Here http://www.rockauto.com/catalog/rafr...k41135-2678608 get the airtex ones IIRC they are like $34. whole bunch of wholesale prices right now so load up
|
so are the bank 1 sensor 1 and bank 2 sensor 1 interchangeable??
|
so something like these??

OK, Mike, you need to change the DOWNSTREAM one right? IIRC Bank 1 sensor 2 is downstream. This would be the one by the cat. Here is a link for down stream... 4 wires http://www.ebay.com/itm/NEW-DIRECT-F...76df41&vxp=mtr
Upstream has 3 wires and those 2 I believe are interchangeable with each other. |
thanks guys

Per http://www.courtesyparts.com/kb_sear...utton=Go&cat=1
Bank 1 Sensor 1, located on exhaust tube near firewall Bank 2 Sensor 1, located on manifold near radiator Which would leave Bank 1 Sensor 2 located pre cat (Under the car) Don't know if this has helped at all or just confused. :laugh: I'd just search UPSTREAM and DOWNSTREAM on ebay. So NO, the one you posted in your 1st post will NOT fit DOWNSTREAM. |

You're close - Sensor 2 is always "post" (after) cat. Fed spec cars have one post cat sensor, identified as Bank1 Sensor 2; Cali specs have two post cat sensors. In our Maximas, Bank 1 is the cylinder bank at the rear of the engine compartment; Bank 2 is at the front of the engine compartment.
FED SPEC : Bank 1 Sensor 1 = Firewall side on the Y pipe reachable under the car ( but still UPSTREAM Bank 2 Sensor 1 = Front Engine just below engine mount on the Y pipe Upstream as well Bank 1 Sensor 2 = POST cat downstream after all the emission crap on the stock pipe. Upstream sensors are interchangable with each other. Downstream will NOT work anywhere else but Downstream. |
They should have just named them starting from the front of the car 1, 2, 3 :laugh:...this whole "bank" and sensor number is just confusing. I'll have to save this thread though for future reference.

Partially yes, but you left out the most important qualifier, The banks shows the physical location, the SENSOR NUMBER tells you whether it is up stream or downstream.

the first ebay link at the top is for the main oxygen sensor, the one that determines your air to fuel ratio, bank 2 sensor 1. I just bought this oxygen sensor and its working great so far for me

I have finally found a diagram that makes sense to me, and I thought that I would post it for all to see. This website allows you to input your specific vin# and receive detailed diagrams of the parts "http://www.nissanpartszone.com".

Our engine is a V shape guys. 2 different banks. Every direction in a car is given as if you are on the drivers side. So left is always radiator side and right is always firewall side. Just call and ask the company you are ordering from if you have questions its not embarrassing to not know something and a whole lot better than ordering the wrong part anyways

My head hurts.
Stoneyburt's picture and Promethius's nicely summarized post are at odds wiith each other:bonk: DW |

@Wizard (By the way bad *** tail lights man..)
This diagram shows both Federal and Cali specs. From what I understand Federal: Bank 1 sensor 1 Bank 2 sensor 1 Bank 1 sensor 2 as Phromethius stated "Bank 1 Sensor 2 = POST cat downstream after all the emission crap on the stock pipe." Cali: Bank 1 sensor 1 Bank 2 sensor 1 Bank 2 sensor 2 Bank 1 sensor 2 In that order according to the diagram (LH, RH). @dwapenyi And now my head is hurting again and has been since 2005, but I believe this is how it goes and I agree with ShocknAwe I am going to call rock auto before I order this Bank 1 sensor 2 (H02S12) and ask to make sure. |

^ thats right. on my car, the vq30de engine. the odd number cylinders(1,3,5) are closest to the firewall and thats bank 1. The even numbered cylinder(2,4,6) are closest to the radiator and that is bank 2. I misspoke earlier about the banks when I said the radiator side is bank 1 and firewall is bank 2. This should clear it up but nissan calls both front heated oxygen sensors and they will fit both. The only different ones are the post cat and those WILL NOT fit on the y-pipe locations. Or if you are a visual learner:
http://www.jatan.net/cylinders.jpg http://theconnectionclan.net/dan/02Sensor1.jpg and this is the fed spec: http://memimage.cardomain.net/member...5_134_full.jpg so as you can see the 02 near the cat is also bank 1 which is a bit strange but it is what it is. Again Nissan calls them front and rear heated oxygen sensors and uses the right(firewall) or left(radiator) directions but I believe all of the 02 sensors the cali and fed spec share are the same wire color and the cali spec cars just have other sensors with other color wire. Hope this helps. |

Picture is wrong as far as labeling the banks for the upstream (before the cat) sensors. Bank one is always the bank with cylinder #1; in our vehicles cylinders #1, 3 and 5 are in the REAR bank next to the firewall.
I think your right about my labels: Bank 1 sensor 1 Bank 2 sensor 1 I have a 1999 SE (Federal 3 sensors) Can we agree that for my vehicle Bank 1 sensor 2 is labeled correctly in my diagram and in Shocknawe's diagram the label is: H02S2-B1 Rear O2 sensor B1 (White) The part # we should look for is 226A0-0SL710? I want to order one for my car but I do not want to get the wrong one or have a parts guy insist on the wrong one. |

Bank 1 sensor 2 is labeled correctly ..... ShocknAwes diagrams are correct for everything, so I would just use that instead. Fed and Cali Spec cars have the same banks. The difference is that the Cali spec car has more O2 sensors. DW |
Bank 1 sensor 1, should be a 3 wire 02(2 white, one black, closest to firewall). On the actual sensor itself has 3 holes drilled down the sensor. And that sensor will have more wire than the rest. Also do NOT drop the sensors, I read that a foot or more fall can cause the sensor not to work. If u r FED spec u only got 3 sensors, one near the firewall of the y, one closer to the rad, and one after the cat converter(4 way).
|
Yeah sorry to confuse guys, my run down applied ONLY to FED spec. I just redid all my sensors, did like three months of research before hand on such a simple job. Thats why I know about the FED spec. my summary is correct for Federal maxs and SHocks diagram for CALIFORNIA spec is correct for Cali maxs

I don't know. I know the wiring is different and pretty sure only the front left one measures AFR.
front O2 sensors as identical with the same part# 234-3098 Amazon is selling them for $43.94 each with free shipping!! http://www.amazon.com/Denso-234-3098...3567364&sr=8-1 So the question is, are the front sensors identical, interchangeable? |

These sensors are so confusing i spent hours reading about them.I also need oxygen sensor bank 1 sensor 2 for my 1997 Maxima which is downstream sensor and from reading this thread it's 4 wire sensor and Denso is decent brand so i just ordered 1 from ebay but still not 100% sure if i got the right part.Can somebody please confirm this sensor i ordered is in fact bank 1 sensor 2,here is the link http://www.ebay.ca/itm/350824572393?...84.m1497.l2649
Thanks in advance guys. |

If you look under the Compatible vehicles listing it is labeled as a Downstream sensor. I would say you are good with this purchase. You needed a downstream and ordered a downstream. Looks right to me!
|
I know the 95/96 maximas have the downstream inside the catalytic converter and the sensor is much smaller. I would go under the car to verify that your sensor is inside a pipe and not in the catalytic converter.

BUMP
my car has P0155 02 sensor heater circuit bank 2 sensor 1. Cali Spec 1999. can anyone point me in the right direction as to which 02 sensor i need ? pm me an ebay link or whatever please |
