24302 Oxygen Sensor

Purchased two of these after getting a check engine light (CEL) corresponding to OBDII code P2195, “O2 sensor stuck lean, Bank 1, Sensor 1" on my 2003 Honda Accord LX 3.0 V6. In my case, the malfunctioning oxygen sensor corresponded to the bank 1 (rear bank of cylinders), upstream/upper oxygen sensor (sensor #1). I ordered two of these to replace both sensors - even though the upstream sensor on the other cylinder bank was still fine. These sensors ended up being exact OEM replacements for the original factory sensors on my Accord and even bore the exact same identification numbers as the original sensors, which were stamped LZA08-H2 - NTK JAP. I disconnected my battery, installed the new replacement sensors, and the engine ran fine and even cleared out the CEL on its own. Have been driving it for several weeks with absolutely no problems or recurrence of the issue, so this was a good fix. I would recommend purchasing or borrowing an oxygen sensor socket (btw, these require a 22mm (7/8") socket), as it makes the job of removal and replacement drastically easier and a real time saver. If you're interested, check out the ARES part #70039 3/8" drive by 7/8" (22mm) Offset Oxygen Sensor Socket, also sold here on Amazon for between $8-9 (as of Dec 2018). That is what I used to do the replacement, and it literally took me less than 15 minutes total to do the removal and replacement of both sensors - easy peasy.

The Check Engine Light came on the other day in my 2006 Honda Odyssey with 167k miles and when I pulled a P0154 code "O2 Circuit No Activity Detected (Bank 2, Sensor 1)" so I knew my oxygen sensor was bad.The only question I had was whether to pay dealer prices for OEM (can't go wrong with OEM) or check Amazon for something equivalent.In this case, I got an OEM part AND saved around eighty USD by going with Amazon AFTER confirming that the NTK oxygen sensor was an OEM part both by checking online forums and NTK's website directly.My defective Bank 2, Sensor 1 oxygen sensor is the radiator side, upstream (BEFORE the catalytic converter) so it took all of 15 minutes to replace (and that includes taking a break to take pictures too :) ).I used an oxygen sensor socket (Tekton 3/8 inch drive socket in my case), a short extension and a swivel head ratchet to make quick work in replacing my defective oxygen sensor.If only life was this easy!

Engine light off after the replacement :)

replaced same factory NTK sensor. Code cleared and gone for good.

NTK/NGK is the genuine OEM O2 sensors for Honda & other makes, so I bought this for my 2004 TL. It is made in Japan & fits & functions as designed to. I have installed high-flow cats, but I kept the original cats just in case, with the original O2 sensors still attached to them.Honda-stamped sensors (the sensor itself actually has NTK stamp, not easy to read though) cost twice as much as NTK, even though they are the same parts. If you drive a Japanese car and if the O2 sensor fails, go with NTK at Amazon unless yours came with Denso.

When I received it, the wires were not in the correct plug locations for my application. It was the correct unit for my application both in the Amazon look up, and on the MFR website. Good thing I compared with the old unit as the sensor is in an awkward spot to remove it, Had to disassemble the plug and re-pin it. This isn't hard, but should not have to be done.It installed fine, and works great now.

Hello,The code said replace both upstream 02 sensors. I bought both and installed successfully. Then the codes of many colors hit. The ODBII tool showed that the HO2S2 sensor was failed. After looking at live data, the HO2S2 was not getting powered on. I used my FLUKE and tested for power to this 2nd O2 sensor source. All ports were powered up. This showed that the O2 replacement was DOA. The H02S1 is working fine and is powered up. Many errors are the results.

Legitimate OEM Made In Japan NTK O2 sensor. Arrived in a sealed plastic package and installation went smooth. Had a P0134 code and my old sensor was exactly as the one I purchased from Amazon. Fixed the issue and no more CEL. Save yourself the frustation from buying cheap Denso knock-offs and Chinese sensors from eBay and buy it from Amazon, since the price is reasonable.
