I have a code 52 and I just removed my sensor and wire, the old one is a Matsu˟˟˟˟a and the other one I have says Toyota, this one came from a guy on ebay who had one listed for a 3.0 with low miles so I took a chance, I'm trying to test both an ohmmeter yet I get no readings on qcv or ohms, only signal I get is when it is set to 200m, I'm getting reading of 0.25 on the one that says Toyota and the other is reading at 0.16, should I take a chance and use the new one or just replace the wire and keep the old sensor, there is a small crack on the housing for the connector on the old KS, just trying to make sure I do this right

 

Aww ... YotaTech is so wholesome it won't let us even spell out the name of the Japanese harness manufacturer.

I don't know what "csv" is. Or "200m."

The sensor wire (sometimes called "pigtail") has a 2-pin harness-harness connector, and a 1-pin connector to the knock sensor. The two pins go to a shield and the knock sensor. You should get continuity (zero ohms) from one of the two to the knock sensor end. You should get no continuity anywhere from the other pin.

Could you have been trying to get a reading between the two pins?

 

Well even stranger I got drops in voltage on the new sensor when doing the knock test, yet the old sensor shot up to 3.5 and 5.5 the 2nd time

 

I'm only getting readings in millivolts, the old sensor was putting out somewhere around 01.6 while the other sensor was putting out somewhere 02.3, like I said when doing a knock test, the old sensor tested better than the other and once again where the hell did this sensor come from, it's a Toyota sensor, it's stamped onto the metal, yet my old sensor is a Matsu˟˟˟˟a

 

Well at this point I'm pretty damn sure the eBay seller sent me the wrong part, on the left we have the sensor that came out of my 3.0, as you can see, it's got a blue ring around it and has an M stamped on it, which I didn't know this but Matsu˟˟˟˟a, the same guys who manufacture cassette deck motors, also happened to manufacture Toyotas knock sensor a during this era of 4runners

The sensor on the right says Toyota but does not go to our 4runners, this one I'm pretty damn sure fits the 3rd gen models that have a 3.4L in them, and as far as I know, those ones have two knock sensors,

My part #: 89615-50010
Most likely the part number for this:89615-12040

So I'm hoping the eBay seller will make this right and send me the right sensor or I'll have to return this, which really upsets me because I'm actually fixing this for my wife and was trying to finish it before Christmas

 

Matsus.hita(Panasonic), along with Tokarika is/was a vendor of electronics that Toyota used heavily.
This may be way off base, but the one on the left looks more OEM legit than the one on the right. The stamped "Toyota" just doesn't seem right. But I could very well be wrong.

Not crazy about using a used knock sensor, regardless of who made it, on a 3vze; but as far as Matsus.hita is concerned they made great parts.

 

The one on the right looks like the one on my 86 22RE truck. Toyota 89615-50010 Knock Control Sensor

Toyota 89615-50010 Knock Control Sensor

So should I throw it in? That part # matches exactly my car, and although they look different, I guess if the part number matches, then there should be no problem right?

Also I am having a hell of a time removing the timing cover, some asshole before me when they changed the PS pump, they made the reservoir tilt when they put it all back together and the way it's tilting is blocking the timing cover from slipping out, the bolt is out, the cover can't slide out past the reservoir unless I force it but I probably will end breaking the plastic on it


Any suggestions on that?

 

Take the reservoir off and mount it properly.
No opinion on used knock sensors. I'd buy new from a known source(pigtail, too). It's too much a nightmare to fix if it throws codes.

 

Trust me it's a concern I have too but my local dealer wants 300 dollars for this sensor and the way that life is right now for me and my family I can't afford that, even if I could to be charging that much for a sensor as big as my thumb is ridiculous

 

Look at Amayama.com
I've gotten a lot of stuff from them.
no sales tax, which makes the shipping costs perfectly acceptable.

 

I buy a lot of my 86 truck OEM from Conicelli Toyota of Conshohocken, PA. Found them to usually be the lowest cost for most parts. They have "your part #" from above post for $185. https://parts.conicellitoyotaofconsh...sor-8961550010. My two local dealers don't carry much of any parts that old.

They have been very helpful in answering general questions as well.

Toyota OEM sensors aren't cheap, but found them to work better than many generic aftermarket sensors. Like the Oil Pressure Gauge sensor.

 

$121.00 on Amayama

 

Nice price for an OEM one.I'll have to put them on my check price list

 

Do you have to drain the PS steering fluid before you loosen the adjustment bracket? I just want to move it out of the way and put it back correctly after I remove the cover

 

I'll have to put them on my check prices list. For an OEM one that's a great price.

 

You should be able to leave it full so long as you don't tip it over too far.
I R&R'd my heads without draining the PS.

 

Amayama isn't always the best, and not great for big stuff that's hard to ship. But for many things, and especially bearings and engine parts, etc. they smoke it.
Just gotta price check. I'm cheap. i want the best parts and pay the least I can. And that means out the door cost(tax., shipping, etc taken into account.). Some USA dealers selling online are falling back to that low price but high shipping and handling charge format. That doesn't work for me.

The best thing about Amayama's website is they give you a running total, with shipping, as you add to the cart. So you can see how much each item you are considering buying affects the total price.
I always pick the cheapest freight because I'm willing to wait. Even then it's not bad. They ship from a few locations(U.A.E and Japan) so when I'm building an order I try and pick parts that will ship from the same location. That way I only pay the base shipping charge once. Their communication is much better than most online sellers, and their packaging is stellar.

 

True on the shipping cost being high for many. I always shop prices. I'm in SE VA, so PA shipping isn't bad. Conicelli for US dealers has consistently been lowest I've found on most parts. Most other dealers are about the same, but a bit higher. Conicelli is great for submitting questions and them getting answers quickly. Packaging is very good as well. Never had any issues. My local won't even quote parts for my 86.

I'm still confused on how I ended up with a knock sensor that is apparently for 2nd gen 4runners, yet none of the genuine knock sensors have a Toyota stamp on them, they all have an M for Matsu˟˟˟˟a,even the 3rd gen 4runner still use Matsu˟˟˟˟a OEM
