Real Denso Knock Sensors?

Are these real Denso knock sensors? Already got one set of fakes on Ebay.
Thanks

 

The question should be, where did you buy it from…

 

Buy them from Toyota...

 

Too important to save a buck. I am not sure about these particular sensors but some of them don't even like to be handled roughly. No eBay for sensors.

 

That very well could be a real Denso but I thought the OEM for these was Matsushita

 

Both Denso and Matsushita made OEM sensors. Supposedly the Denso ones are better, the ones in this truck are Matsushita. Once the old ones are out I'll post some comparison pictures.

I've been going further down the rabbit hole on this issue. Paying $250 each for these sensors is stupid. MSRP is just over $200, and they're readily available from dealer sites for $130-$140. The originals in my truck were Matsushita. The Ebay ones above are real Denso sensors, but one was manufactured in 2008 and appears to have been resealed in the factory package. The one that was made in 2018 appears to be in its original package with the original seal. One more is on its way from a dealer, I'll post an update when it arrives.

• Real Denso sensors have the black sealant around the plug and another ring around the edge.
• Both Denso and Matsushita made the sensors.
  • Denso has a hole in the bottom end, Matsushita has a cap
  • Matsushita has no black sealant, a raised portion on the top, and grooves around the circumference where the corners of the wrench flats would be.
  • The plug alignment/orientation ribs on the two are different. Denso have one large and one small, Matsushita have one small and two small on the other side. The effect is the same, plugs fit both.
• Real Denso sensors have a manufactured date code
• Fake Denso have no date, black sealant only around the plug. Both the fakes I got have gaps in the black sealant, it was done poorly. They also had terrible quality plastic plugs.

The two real Denso sensors from Ebay. Different dates on them. One on the left had been resealed in factory packaging. Fakes do not have these stamps.


Sensor on left is from 08. Looks to have been resealed in original package. One from 18 on right. This packaging matches what is on the partsouq website.



Terrible plug quality on the fake. Denso sensors also have a number molded into the plug




Fake on the left, Denso on the right. A component is clearly visible inside the fake. Whatever is inside the Denso is set far enough in that a flashlight is required to see it.


Matsushita on left with grooves and enclosed post. Denso on right.


Denso top, Matsushita bottom. There are markings on the Matushita, but they don't appear to be a manufacturing date.

 

I've read several posts here on TW, that the knock sensors very rarely go bad, unless you have really high milage. Many users on TW world only change the knock sensor cables. Someone chime in that knows more than I do.

 

in my experience EVERYTHING listed on ebay/ Amazon as authentic Yota parts is counterfeit. ALL OF IT!

Only buying from a trusted Yota dealer/ online parts store will insure you get authentic parts

your truck your choice

 

Yeah this is the experience I've had as well but I've gotten tired of repeating myself.
