Hello All,I tried searching and also couldn"t find the prize I"m looking for, so carry out apologize if i didn"t look at harder. I have a 2012 Odyssey and am trying to locate the downstream O2 sensor. I found the upstream O2 sensor, in the prior of the engine, however I"m no too sure on whereby the downstream one is. I couldn"t find any type of diagram or video clip online for 4th generation odyssey, concerning O2 sensor. If there"s anyone that is kind sufficient to assist point me in the ar of whereby the downstream O2 sensor is, that would certainly be lot appreciated. Images or screenshots would certainly help. Thanks,Matt

Bank 1 sensor 2 (O2 sensor) is situated in the rear, closest to firewall.Bank 2 sensor 2 (O2 sensor) is located in the front, behind the radiator. Both A/F sensor and O2 sensors room on the cat. Some models have actually the financial institution 2 sensor 2 on the j-pipe.Do friend have any type of codes?

Thanks MrRangerZr1. Password P0430, Front financial institution Catalyst device efficiency listed below threshold (Bank 2). Ns replaced bank 2 yesterday, however thought ns might as well replace bank 1 as well. You re welcome if friend have any type of sort of visual view of where financial institution 2 is, that would certainly be wonderful. This is a dumb question, yet what is a firewall? mine guess is the wall between the engine compartment and the other side that it?

Thanks MrRangerZr1. Code P0430, Front financial institution Catalyst system efficiency below threshold (Bank 2). Ns replaced financial institution 2 yesterday, yet thought i might as well replace financial institution 1 together well. You re welcome if you have any type of sort the visual view of where bank 2 is, that would be wonderful. This is a dumb question, but what is a firewall? my guess is the wall between the engine compartment and also the other side the it?
Yes that"s the firewall. The end the cabin and engine bay.If girlfriend replaced bank 2 sensor 2, that way you changed the O2 sensor behind the radiator. The bank 1 sensor 2 is the behind sensor, you"ll have to go under the van to get accessibility to it. The plug is top top the top. Prefer I stated before, generally both A/F sensor and also O2 sensor are on the cat itself, your is on the cat. Bank 1 sensor 2 is #21 ~ above this diagram: https://www.hondapartsnow.com/parts-list/2017-honda-odyssey-5dr_tourin_elite-ka-6at/converter.html

A pair of points to mental here.Upstream vs. Downstream is in recommendation to the converter. You car has 2 converters that room monitored by O2 sensors. Financial institution 1 and also bank 2 ad t the "bank" the cylinders. Financial institution 1 is always the financial institution of cylinders that has actually cylinder #1 in it. Bank 2 will be the various other bank. Withstand the urge to think that bank 2 must have cylinder 2 in it due to the fact that that"s incorrect. In ours case, financial institution 1 has actually cylinders 1, 2, & 3. Financial institution 2 has cylinders 4, 5, & 6. Some cars it will work out where financial institution 2 will have cylinder 2 but it"s simply coincidence. Once you find out that friend can number out any O2 sensor location. Sensors are referred to as bank X Sensor X whereby the financial institution number is as explained above, and the sensor number needs to do v upstream (sensor 1) and also downstream (sensor 2.)B1S1 would be bank 1 sensor 1. On the J35 engine that will certainly be the upstream sensor top top the rear bank. B1S2 would certainly be downstream sensor top top the behind bank, and also so on. Hope that clarifies.
