Had to purchase these and relocate it to the outside. Initially I purchased denso ones off of ebay and they were junk. I just left the denso in the engine. Unfortuantely I didn't know they were bad until I finished and the code came back right away. These ones did the trick. I have no idea how long they will last but they fixed the vehicle es300 2003. Rat had chewed the wires. I spent so long trying to fix it either cutting the wire and making it into one to only make things worse. The only thing that fixed it was relocating it out of the engine and attaching it to the fuel rail metal part. Only do this when you are sure its the wire or the actual sensor. If you have issue with the engine itself you will have to fix. Hope this helps.

I relocated this to the outside of the cylinder head. Works fine like this

Installed easily(once you removed upper and lower intake manifold/plenum) product plug and play. Check engine light has not returned for this particular reason. Limp mode has not returned. Product well built. Torqued to spec. Would purchase from vendor in future

these sensors will not work on a lexus rx300 , the sensors do not carry the correct resistance as the factory sensors , its to much work and time wasted to find out you have to buy the factory sensors and harness just to do it all over again, and i hate having to do something twice . if your sensors are under the lower intake , just bite the bullet and buy factory parts to install and don't make the mistake like i did, l have learned a lesson the hard way ,so you want have to, good luck

The knock sensors were a perfect replacement for the Camry I was working on. The problem with them is the connector on the harness itself is very similar to the factory but will not clip on. Remedied the problem by using a zip tie to secure the connection.

A pain to install, but worth saving over $1,500
Disappointed

I generally don’t give reviews but due to the amount of work to do this procedure I should share my experience.While the sensors appear to be of good quality, the harness connector that goes to the factory harness does not fit securely. The issue is as shown in pictures, the OEM plug has thinner side walls than this Dorman one. It will only go in until hitting the rubber seal. I ended up using the OEM plug on the new harness so it would actually click lock in place. This requires pulling the connection blades from the plugs to swap them.One other thing to note is that the new harness has a slightly higher impedance than the OEM harness(.00 vs.01). Probably doesn’t make a difference but worth mentioning. OEM has gold plated leads and heavier gauge wire

This installation took me very very very long. I ended up getting a set of gaskets, an angled ratchet for those stubborn bolts behind the plenum. I also did the spark plugs and ignition coils, half are buried under the plenum. Save yourself some money and buy them from RockAuto if you are in Canada, amazing prices, fast shipping. Also, get some coolant or drain it beforehand because it'll need replacing. Overall, hoping that these things last. Will update if anything changes.

Fixed the old one that were tripping the knock sensor codes on my 2001 toyota highlander with 278,000kms

Once again I thought I could cheap out and buy this quick change kit but it ended up causing more issues! Unsure why whether it be bad sensors or wording harness was wired wrong, the 4 pin connecter would not click in properly so I had to zip tie it and after installing had huge loss of power and went from 1 code too 2 bad knock sensor codes aka DO NOT BUY!!!
