Base line results for 322,000 mile 98 Honda HX 5 speed

[DSMHondaGuy]

SOB, got a CEL on the way home.. P1165 damn it. I'll check wiring and connections but chances are I'll be coughing up $200 for a new Denso primary wideband O2 sensor.

Hmm maybe my mileage will be better after it's replaced if this one just died as I doubt it was working well right up until it died....if it is in fact dead and there's not just a bad connection. Is there a preferred sensor? I'm looking at this one https://www.autozone.com/engine-mana...784_3498_97999

Also any idea if the car goes into a default somewhat rich A/F mixture until the sensor replaced and code cleared?

Everyone says that only the factory sensors work and they are expensive, but you can find them for less than Honda charges. $200? Please.

Eek. I don't know about that sensor. They're sensitive to having the right one and I can't guarantee that's it; I don't know about Denso or the HX, but I know some Chryslers won't run correctly on an aftermarket O2 sensor...NGK made them for some Chryslers, but the OEM and aftermarket businesses were different entities (NTK was NGK's OEM division), and you wanted the NTK sensor made by NGK's OEM side from a Chrysler dealer, not the supposedly correct NGK from a parts store. Given that lean burn relies heavily on inputs, your skepticism is warranted...

Denso and NTK are two of my favorite Asian suppliers for parts like these, they're very good. But you're right it doesn't mean the OEM sensor doesn't have some weird exclusive bull **** going on. If the parts store wants $339 for a Bosche unit, I don't want to call a dealer to see what they want for the "Honda" OEM part.... Of course I also don't want to waste $200 on a part that while it may (partially) work (narrow band portion), wont allow the lean burn mode to engage due to some odd non-standard 0-5v wideband calibration


Just looked up the Factory "genuine Honda" part HOLY CRAP! $497
https://www.hondapartsnow.com/genuin...sohc,2816050,8


Just didn't "feel" like going and messing with it earlier, so I guess when I get home tomorrow I'll check the plug connection on the senor and maybe pull the negative cable on the battery for a bit and let the ECU codes clear and see if it comes back before worrying about it to much. I did at least notice the NTK and Denso sensors were cheaper on Amazon than anywhere else.

I did happen to notice this on one of the review of the Denso unit (on amazon) "Denso O2 sensors are the only ones that belong on a Japan car.

Had a Delphi and it did not fix my issue on my HX, this one did!"

Yup. One reason why although I love the idea of the HX and tried to buy one, I'm relieved it didn't work out. At this age, maintenance items like that specific to its lean burn wipe out the $$$ advantage of its FE gains

Do your own research - I would if I were an HX or VX owner - I can't answer your question but I can validate that you want to exercise caution here. If you can snag something aftermarket (or RockAuto or something), which works, that's a nice win, but be cautious now before having to be a parts changer.

Do you have anything at all which can show you live data from the sensor? The diagnostician in me wants proof it's that before changing it. I know some of the Actron scanners would display things like that, as will my UltraGauge, but the data rate out of OBDII is so slow it's not worthwhile unless it's so dead that there's zero doubt. Guys like ScannerDanner and EricTheCarGuy on YouTube might have some things you can try with more basic tools before condemning the sensor.

It's a wideband so if I know which terminals/wires to tap into it should generate a 0-5v signal. So should..in theory be able to watch it with a multi-meter.

reviews seem, promising. I think it's the fact that it's not just a wideband o2 sensor, because they're not all the same. It's a linear wideband o2 sensor. Most from what I have seen with aftermarket sensors anyway, are NOT linear.


Hmmm similar reviews for the NTK sensor and it's only $144
https://amzn.to/2RDtIdh

tempting.

I did just walk out to the car and look for any marking on the flats of the sensor, noticed 3971. Typed "3971 Honda hx" into google which brought up rockauto link that went straight to 98 honda hX o2 sensors but there's no listing with that number.... interesting


NTK part # 24300
from amazon "This part is the same as Honda uses! a perfect fit exact same stamping on the part as original! a great bargain compared to other sources,I paid 175. flat no tax free shipping!BARMAC AUTOMOTIVE was the supplier.

This was a "real" parts as shown and in original box. This is "NOT a clone part" I was very happy with purchase. I would buy from this company again.
By Jeff C. on October 22, 2014
NTK!! Replaced the L1H1($) used with my Tech Edge, 24300 works great!! About supplies to Honda, not in that loop??
By Robert F. on October 20, 2014
Im not sure, all I know is it worked in my 96 gonna civic hx. Hx only
By Dallas M. on October 20, 2014
It's the original NGK/NTK company which supplies to Honda. I bought it for 99 civic HX and it worked.
By Mohamad Nazari Alikorzani on October 20, 2014
Chris, yes this is the factory part and not cloned. My VX loves them.
By Mark Barrett on October 20, 2014
It's the ntk/ngk product. Solved my problem quite well in a 94 vx"

So if you believe the reviews... seems to work fine. So I guess I'll try the $144 NTK if the wiring and contacts seem fine.

[DSMHondaGuy]

Well, even with the primary o2 sensor dead the car got 35.8mpg with my driving it like a jack ass. *shrug* Soon I'll have the spare coin to replace the sensor and get lean burn working again, curious to see with a new sensor what it does. Then I'll start the aero work.

You found the sensor I linked in post #32?

Hey DSMHondaguy.. wanted to tell ya that I have the denso 234-5052 on my 96 HX and it's a reboxed NTK 24300! Even if you zoom in on the image on amazon.com you'll see NTK on the cover of the sensor.

I've already posted in another thread about my results recently.. Reading your thread made me want to check to see if mine is operating normally. I installed it back in 2014 when the original decided to die. I think Honda is out of their mind charging $400-500 for that sensor! Ridiculous!

but you have found the same sensor between denso and NTK. Only NTK makes it. thought you'd like to know someone here who has been down this road before.

[DSMHondaGuy]

Thanks. To some degree the sensors price from Honda makes sense in that back in 1998 a wideband o2 sensor was a BIG deal. Now, not so much. I'm sure they're trying to make their money on something that at the time was probably fairly expensive.
