Gauging interest: KS212 knock sensor 89615-17010

Hey everyone,
I found a supplier that could provide the KS212 knock sensor replacement for 4agze knock sensor part # (89615-17010) but It would require volume order. I just want to gauge how many people would be interested in purchasing. The more people interested the lower the cost. Please post if you're interested.
Thanks,
Ray

Last time I contacted SMP regarding this, they mentioned the manufacturer of the part (3rd party) was no longer making them.

Put me down for two if you manage to get enough numbers for a volume buy. If it's a genuine KS212, I can guarantee they work.

I'll let you know. Im working on sending pictures of the original knock sensor from my car to the manufacturer to make sure it's a perfect match. Also, I'm trying to get a lower volume so the price would be more affordable. Currently they are requesting for 50 pieces for minimum order I'm hoping to bring it down to 10 pieces.
If you have pictures of the OEM 4agze knock sensor please pm them to me. My car is in the shop and relaying on the mechanic to send me the pics. I was able to get a used knock sensor from a member hopefully it will resolve the situation on Monday but I'm willing to pursue this situation if there is enough interest.

Pictures are one thing, getting a knock sensor that actually works is another..

They can get pictures from the Internet, like here:
http://www.summitracing.com/int/part...s212/overview/

I bought a KS114 clone knock sensor which is exactly the same as KS212 externally. Doesn't work. You can still find them cheap on Amazon.

I hope your manufacturer isn't the same as this one:

Has anyone tired using the ATS GM knock sensor kit on the 4agze with success?
The company is from china I believe it's called SYC but still getting more info.

Do we even know the ATS sensor works on the 3SGTE?
Now I only did 30 seconds of searching and this is the first thread I found so I do not know the answer to this question and if it is important I would recommend doing more research but this thread pretty much confirms my suspicions. Even this thread relies on some basic assumptions like detonation frequency being based on bore size but each 4AGE has a different sensor with a different target frequency.
http://www.solaraguy.com/viewtopic.php?f=2&t=38336

This is why we have to be very careful when choosing sensors. Just like it says in that thread different people may have different ideas of what they consider to "work".
Many people seem to think everything is fine as long as the code goes away. This is not the case if you want the sensor to actually protect your engine.

That's applicable to later gen MR2's and Celica GT4/Alltrac. Yes it's been tried before.

7MGTE knock sensor's apparently work on some model GZE's.

This exactly. The other knock sensor thread was investigating this extensively so we could develop a cheap, commonly used "wideband" or "flat-response" knock sensor with an in-line filter to reliably report frequencies our engine is interested in.
Of all the aftermarket sensors tested, none of them compared to OEM sensors.

I've also made it very clear in the other thread I have two intentions here: 1 - I have a cheap, easily rebuild-able GZE I'm currently running, that all I want is a no CEL/spark retard on. I don't push this engine so I don't care if it doesn't detect knocks, I run quality fuel as well.
2 - I'm currently building another engine that will be run on stock management but higher CR though stock boost. Reliable knock control is very important for this engine since I'll be spending my budget on parts for it and want it running at it's best all day every day, whether its on the street, track or drags.

I just got the email today in regard to the manufacturer it looks like it's the same link you provided as quoted above. I guess thats bad new, then.
Did you guys try this company before?

I wouldn't trust any chinese based knock sensor company.

I'd suggest you ask for oscilloscope resonance output and if they'll sell/lend you a sample so you can test in car first.

Since you have a laid back GZE why not experiment with this Jinyi on that engine?? It's denotes right in the ad that you linked that they provide samples.
If you are blowing off "oriental" manufactured parts? it seems foolish your not considering your putting them into your "oriental" manufactured engines.

Just because the parts are made in the same part of the world, how does that translate to them being just as good as each other?

Denso/Toyota investing millions into engine and ECU development in JAPAN, versus an unknown manufacturer in China making cheap knockoffs?

Have you visited Alibaba/Aliexpress? China has no concept of intellectual property and copyright infringement. They'll make any rubbish look identical to anything else.

If you look at the other knock sensor threads, I've tried fake KS* series knock sensors. Guess what? they don't work.

Sure if they're willing to give a free sample, go for it, TEST IT. That's what my last reply already mentioned.
If you want buyers to invest in a group buy, you need proven results.

Testing knock sensors is not a matter of slapping it on your motor and seeing if it works. Not that you should do that with any other electronics either without the right tools to monitor the effects. Some components like a fuel injector don't take much. Add a wideband and you can see the effects that a different injector has. Testing knock sensors properly take a lot more than that. Initial testing should really be done on a bench with the right equipment. Then it wouldn't be a bad idea to make sure it actually operated properly on the car but this would be rather challenging making sure the ECU saw the knock signal and responded properly.

Well, guys I haven't heard back from the manufacture since I sent the photo's of my OEM sensor. On side note I went ahead and purchased a used 4agze knock sensor which didn't work to fix my problem. So I went ahead and purchased a new OEM 7mgte knock sensor. Its been installed and seems to have fixed the 52 code and car has been running great. After looking on the web I found the frequency and bore to be pretty close to the 4agze. My car is driven rarely and I'm willing to take that risk. I have 3 other cars that me and wife shares. Since my car is fix I'm no longer going to pursue the group buy any further. I wish you guys all the luck to finding a better solution. I look forward to see what you guys come up with.

Can you confirm the part number you used? Was it 89615-30020?

I've been thinking about buying a Toyota genuine one for a while but I wanted confirmation it wouldn't throw code 52.

Also note the 7MGTE sensors are used in pairs, so a single one probably does throw something similar to a 4 cyl GZE. Would be fantastic for someone to bench test to confirm.

Can also confirm Toyota genuine part #89615-30020 will not throw CEL code 52. Mine is a JDM imported SC automatic.

I have a smallport ae92 Jdm 4agze motor on my car and worked for me. I used the new OEM Toyota genuine 89615-30020 knock sensor for 7mgte.

Sorry to necro your thread! I have managed to smash my OEM AW11 SC knock sensor whilst getting the head off (it's back on, don't ask...).

There seems to be an awful lot of discussion regarding this thing but few definitive answers, so what I wanted to ask you is:

Now that you have been running a 89615-30020 7mgte sensor as a replacement for 4 years now, how confident are you that it is doing as good a job as the 89615-17010 that it is standing in for?

WARNING: SENDING YOUR KNOCK SENSOR TO A BOARD MEMBER FOR TESTING COULD RESULT IN A BOARD MEMBER STEALING THE KNOCK SENSOR.

THIS HAPPENED TO ME.
