P0141- 02 sensor part number?

After doing searches on P0141, I cannot find the part number for the OEM NTK 02 sensors. Looking for the part numbers to compare pricing....

I assume I need Post-Cat front and Post-Cat rear? @ oxygensensors.com, looks like I can get Denso's:

POST-CAT FRONT : 234-4093
POST-CAT REAR: 234-4094

Anyone running Denso's, problem free?

Do you mean these?

36541-PR7-A51 SENSOR, FR. OXYGEN SECONDARY
36542-PR7-A51 SENSOR, RR. OXYGEN SECONDARY

Not sure, but do you know which one is for P0141? thanks!

ngk #'s

post front 24633
post rear 24584

Cool, thanks.. I talked to an Acura dealership. They said I just need one sensor (OEM: 36542-pr7-a51), just one sensor. the rear bank last sensor. Is this accurate for the P0141 code, or do I need both that you folks have been posting? Thanks

^ bump?

When I get a sensor code, I replace all of them at the same time just for the hell of it. I get mine at sparkplugs.com. They're all the same crap, just get the most inexpensive ones. NGK, Denso, Mammalickabooboodeh, NAPA, Doritos, it doesn't matter.

I'm just confused on how many sensors their are total? 4? Two pre-cat, two post-cat? Since P0141 is post-cat, I hear they are much easier to remove, whereas the more important pre-cat 02 sensors is a major PIA?

On my 93 there are only 2 sensors. I believe your 02 does have 4 of them. Double check with LarryB or BrianK or check the online parts diagram at http://www.acuraoemparts.com/

that's correct on 91-94 has 2 o2 sensor on 95+(OBD II) it has 4 sensor

Thanks guys for the responses. Anyone have a diagram where this sensor is located? I just ordered the 02 sensor for this particular code and wanted to ensure I removed the right one. thanks!

i always thought the right NTK part #'s were 24172 that most here have also used?

Not sure if NA2 is different. I looked it up via sparkplugs.com

Correct part number for code is: 36542-pr7-a51. Install was 15 minutes, tops.

synth19 can you tell me if it was right or left that you replaced ??
