Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to be working with our 1998 Toyota Camry. We're going to show you how to remove and replace your knock sensor on the back side of the engine.
This part senses pre-ignition or spark knock inside of the motor, which means there's an issue with compression, ignition timing, fuel mixture, something that's causing the air fuel inside of your cylinder to go off before it was supposed to. This is detrimental to the engine and all of it's internal components and can cause catastrophic engine failure. Your knock sensor picks up on this little vibration or noise that you normally wouldn't hear inside of the car and de-tunes the engine accordingly to make sure that it runs within safe parameters.
If you like this video, please click subscribe. We have a ton more info on this car, as well as many other makes and models. If you want this part for your vehicle, it's available from 1AAuto.com. You can follow the link down in the description.
The only item we'll need for this repair is a 27 millimeter socket and ratchet. We're doing this on a lift, but this can easily be done at home with a jack and jack stand.
If you raise and support the front of the vehicle, you can find the sensor below the intake manifold on the back side of the engine. You can reach up between the CV axle and the exhaust. Push down on the tab. Remove the electrical connector. Use a 27 millimeter socket and ratchet.
Here we have our old knock sensor that we removed from the vehicle; and our new knock sensor from 1AAuto.com. As you can see, we have the same single wire connector at the top. We have the same threads on the sensor end here. We have the same 27 millimeter hex for our wrench. So, if your knock sensor has gone bad and is causing the check engine light on your vehicle, this new part from 1A Auto is going to go in, direct fit, just like your original equipment, and fix you up right.
Install your new knock sensor into the threads on the back the motor. Bring it down as tight as you can by hand. Then we'll finishing snugging it up with a 27 millimeter socket and ratchet. Reconnect the electrical connector, and you're good to go.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.

The product was received quickly and was an exact fit. Cost about a third of the price of the auto parts stores. Installed the knock sensors and wiring harness two weeks ago and it is running good.
So far so good

I ordered knock sensors and wire harness for my 1999 Camry when I found out the shop where I took it to wanted around 200 bucks just for 1 knock sensor. I bought a kit with both sensors and harness for about 60 bucks had the shop do the labor and everything is good ,going on a month now. Happy so far

As I looked around all my neighboring automotive parts stores and a bunch of online vendors I was highly skeptical on the price and the quality of the material. But I've had it in there for a couple years now and hasn't had any problems Parts hooked up perfectly like they was Factory everything works beautifully
Good Quality

Ended up buying a kit for my v6 camry because knock sensor 2# was failing so I thought might as well replace everything. One day after the installation I get a check engine light again this time for knock sensor #1. So now I have a faulty knock sensor that is brand new and I have to get someone to open up my car again to replace it with a better part.

Knock sensors & wiring harness for Lexus ES300

I bought the Knock Sensor Hardness package set from 1A Auto for my 1998 Lexus ES300. The package consists of 2 knock sensors and 1 wire hardness. All items fit perfectly and the check engine light on the Lexus is now cleared.
I checked prices of the knock sensors from my local autopart stores, and the cost for 1 sensor is almost equivalent to the cost of the package set from 1A Auto. The 1A Auto package set is a great value and a perfect fit. I would highly recommend this package set to Lexus owners who need to replace their knock sensors.

Customer Q&A
Do this replace the front and back knock sensors of the 1999 lexus es300?June 8, 2016

Hi Kensey,
I ordered this harness for my 1996 es300 and it was for both the front and rear Knock Sensor which are located just across each other under the intake manifold. I would recommend you replace both sensors as well while you are going to go though all that trouble of removing the air Plenum, intake manifold ect. I am assuming the '99 is very similar to the '96. Hope this helps.
