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.

It is my first time purchase from 1a auto... I was a little skeptical at first about putting it in, because of how much more cheaper it was from any auto parts store in my area... so I went and bought it and it arrived a few days later I went and installed it took me less than an hour, and also made me realize I need a couple other new things I need to get too... this site was much help....
Good people good personal working there

Spoke with customer service prior to ordering to ensure proper fit. Sensor got here in 3 days which is awesome. Was having my oil changed at the dealership and asked about cost to Install part. They said we have it on the rack already so an additional . 25 hours to $23. I agreed and they install the new part and reset the light. The light came back on during my drive home and I returned to the dealership. They said same code and pulled the part back out. The used a multi-meter to check it and advised it was far off spec. They showed me the difference from their part and the A1 part. My old one was just starting to fail and triggered the light once in a while. I had them put the old part back in, they did not charge me to do so. A1 is sending a new one out to replace the old one. Im hoping it works. The light has not come back on yet with my old part installed.
Beware
