Dorman 926-387 Knock Sensor And Harness Kit Compatible with Select Lexus/Toyota Models

Parts fit perfectly and solved the problem. I had a knock sensor code and it wouldn’t allow the car to shift the transmission into higher gears.I’d recommend this kit

Its a big job to do, But these sensors threaded in nicely, Dorman products usually play well with Toyota fitment. The Price for these were off the charts great for what you getting. I will know more once I drive the vehicle and turn off the check engine light.

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

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

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.

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

Dorman Knock sensors cheaper on amazon - same product expensive in autozone.Very good quality !No more check engine light :)
