Well done. Thank you for the information. Your a good man for sharing information like this to people who cannot afford to get their vehicles done in a shop. I know that sometimes, troubleshooting gets a bit expensive when you don't really understand the component and its function and relation to other components. The understanding or knowledge is the reason why mechanics gets the same bad rep as car salesman. Mechanic's lack the knowledge (or does not want to update their skills) and their trial and error style of troubleshooting results in the expense getting out of control which makes the costumer unhappy and doubtful. Well to make this short, there are 3 kinds of mechanics out there: 1 - the trial and error kind; 2 - the know what the problem but makes it look really bad to get more money; and 3 - your kind of a mechanic, the kind that has good principles (willing to share knowledge and for sure fair enough to customers). Your a good man. thanks again
Your channel might not be the most popular in the Automotive category, but you are actually the best and most enjoyable without a doubt! Thanks for all the awesome videos, I appreciate the hell out of your narrations.
Thanks in large part to your great videos, Brian, my '95 Honda Accord EX with nearly 300k miles is running tip top. Thanks especially for your Accord VTEC water pump replacement video. I jumped in way over my head with that one and your video helped me through it and saved my car. Now with nothing to fix at the moment, I still watch your videos (like this one) to: 1) become more knowledgeable in general when it comes to cars and 2) for pure entertainment value! You should be on prime time television my friend. Thanks so much for doing these videos... I know a lot of hard work goes into filming and editing each one. It is greatly appreciated. Peace!
WOW, the actual internal of the sensor is soooo crazy. Sorta of xtal microphone ... Thanks, really the best vid on knock I ve ever seen. You never dissapoint !!!!
Hey Brian, great work!!! i think knock started appearing mainly due to the low octane fuels as lead was banned (being toxic and damaging the catalytic converters). Cheers!
You are a very talented teacher. Lot of very smart guys making videos but don't have a natural ability to teach. I rate you up there with ETCG, SCANNER DANNER, REALFIXES REALFAST, SMA, Mandy ETC. I'm grateful Brian, thank you.
Brian I have had good luck with Standard/Bluestreak knock sensors for LS engines. Last one I did was my own 2500hd. I have yet been able to remove the harness connector without it shattering so I always order a new harness. It's quite expensive paying someone to change them out so going with a factory part is probably worth it. Great info 👍
thank you so much for your videos. I went to change my wife's breaks and was immediately presented with your dodge journey brake video I looked up knock sensor and here you are again. Please keep them coming Brian, I know jack crap and appreciate all your help.
Very cool when guys like you are willing to spend your time helping others. Cheers
Thanks a ton for the video, I just went through the painstaking process of replacing the knock sensors on a 06 2500HD. I went with the OEM from the dealership (GM Part No.), Bench tested both with a multimeter before install and at various points during installation. So far so good!
Great explanation video, Brian! I like the knock sensor bench test with the vice. The only thing you really need to confirm proper knock sensor operation is an OSCILLOSCOPE! The voltmeter on the AC scale only gives you a general amplitude of the signal. A faulty knock sensor may still produce the right amplitude, but the signal will be very erratic and choppy instead of a smooth sine wave.
Recently had an '01 Lexus RX300 in the shop with an intermittent P0330-Knock Sensor Bank 2 code. On the bench, both B1 and B2 sensors showed a similar signal. However, zooming in on the waveforms, B2 looked more like a ragged square wave compared to B1 which was a smooth sine wave...pretty awesome. No other way to confirm the fault. Knowledge is power!
Hey Ivan do the new style knock sensors on Chevy ls3 ever fail to sense detonation and end up causing the timing to advance too much or do I have another problem if I have detonation

Does an 03 durango 4.7 have a knock sensor?
The technology in use in the knock sensor was invented by French Physicist Paul Langevin in 1917 and was first used to detect submarines underwater. All the components of it had been studied since the 1890's, but he was was the first one to put it all together.
Very good and easy to understand video. Thanks for the time and effort that you took to help me and thousands of others to understand this simple concept.
You give great clear info as always. My 06 Cadillac DTS pings it's butt off under heavy load on 93 octane, but no codes. Evidently all carboned up.
Brian best video ive seen in a while!top man
absolutely brilliant video on knock sensor with additional graphics kept me attentive. well done,.
Excellent video Brian with a lot of great info. Knock sensors can be a pain in the arse sometimes. Thanks for sharing all that great smartness.
that is very good , I have been fighting my 95 f150 4.9 and this fixed the spark knock!
I'm doing an ls swap in an old skylark and I kept wondering what those sensors were for! thanks man great video!
Got a po325 on 98 honda prelude. Noticed harness connection coated in oil. Will clean and see if code comes back. If it comes back will replace with oem. Best video out there on knock sensors.
Thank you Brian. My Toyota Tacoma has a knock sensor P0325 fault. Fortunately it's a 2.7 4- cylinder. With a low profile ratchet i can R&R hopefully with out removing intake. A neahbor walked up and said "hay you got hesitation when you accelerate after shifting down?" I said YES but my scanner said it's the knock sensor. He said he repaced the No.4 spark plug wire and that solves the problem. HOLY SMOKES my spark plug wires are original. Stay tuned and thank you again. Conrad
Thanks Brian, very informative, very clear, I learned a lot from it.
I'm gonna share my new found knowledge with the world and seem like a genius. Thanks Brian.
Thanks Mister sir I heard about the nock sensor but I had no idea it was such an important piece of the ingine thanks again.
Hey Brian
Good lesson
You have teach us a lot
Would it possible for you provide series of lesson on automotive sensors
I would truly appreciate your effort in helping us to deep dive in automotive concepts
Dude much respect, You have just educated me and armed me for battle but no seriously man great work and I absolutely love your videos you seem professional but know how to put it in lamens terms for us who don't get it can't wait to see more gm videos and do you have any on cladded avalanche's
Freaking awesome, best video and knock sensors out there! Do you have a plain clear concise way of explaining everything and it’s easy to comprehend. Wish I could ask you questions about my car. For example, It’s got a knock sensor code and it goes into restriction mode is that common?
Absolutely the best Knock Sensor Video on TH-cam!
Great explanation!
I used to manufacture the Knock sensor Body on a multispindle turning machine in the 1990`s when I worked for TRW :)
Thank you dude for sharing this information with us! All the way to Sweden ;)
Love you and eric, thanks for the heads up on apc. Subbed.
Thanks Brian, helpful for my boat.
Awesome. Thanks for showing us the cut away view👍
Good stuff Brian. Thanks!
Great stuff Brian.
Thanks bro " very informative and Mandy has excellent videos as well. Dude is full of knowledge ...thanks.
Thank bud!!! Great vid and hats off to Mandy.
Thanks for the great information Brian.
very cool i had no clue about these things till now
Thanks for the video. Will be testing mine tonight
Great video. Thanks for taking the time to make this. Very helpful.
Question: Does a P0325 error code indicate a faulty Knock Sensor? Or does it mean that the sensor is detecting knock on the block?
Thanks Brian, subscribed to Mandy's channel
Thank you for all the information I have a 1994 suburban with 294,000 miles on it with OBD1 , I am getting code 43 I replaced the knock sensor and I am still getting code 43. God Bless you
best explanation so far, great video.
Thank you so much, incredible video and learned so much . Greatly appreciate this 🙏
Man thanks for the information and the knowledge. This helped out a lot.
Great video. I replaced one on our Honda, only to have it come back on! Now I know why. thanks!
Back in the day... there have always been 2 knock sensors for your engine. They are installed on your head. One on the left and one on the right, typically. Their effectiveness was determined by each persons exposure to and duration of very loud noises like rock music, heavy equipment, etc. Mine are 60 years old and still work, although I do have some ringing in them now. He he...
Great explanation about the knock sensor really help me to understand why my car have one
Good job. Very informative video.
Very good video bud! Thanks was very informative and you made it look not so dang hard. Thanks for the help!
Cheers man, just about to try and replace one of these on my girls car and now I actually understand what it does.
Thank you for showing me how to test the new ones. I was worried about the amazon acdelco products being good right out of the box.... ok, plasitc bag....
thanks for the info dude now im going to replace the sensor mine never did it all the time but once in awhile
it would in a certain temprature untill 30 seconds into warming it up
First time I heard about the hydrocarbons building up to cause knocking. Also the reasoning to get the factory part. p0327 came up on my 05 Rainier. Runs fine though.
Excellent explication Sir! Thank you.
Thank you for putting up this video , make me more to understand about the knock sensor work
It’s very good video and very good explanation
Can I ask you a question
This knock sensor which we have to test resistance
I saw another video it said that if the knock sensor has a resistance is bad sensor, is it true
Thanks for your video & time man!
ADP training, very good info there, also he has a range of books that are also good.
Great video, thank you so much for your work..
You're welcome DJ I love to hear it!
Very informative video ... Engineering is a amazing thing
Thanks for the info! Curious if you happen to know why the sensors are crimped together top and bottom instead of a single piece?
You're video on smoking engine was great too. I'm losing water and oil with no visible leak. Rebuild or junk it? 2005 Sioverado 5.3 crew cab 4x4 with 195k miles
Good job. You are a very smart young man.
I wish I listened to you, just installed aftermarket knock sensors in my Silverado and less than a day later threw a p0327 code FML
Brilliant idea , thanks for sharing
Best in-depth explanation of knock sensors I've seen so far!

As always an interesting and informative video - Thanks Brian!
Definitely subscribed
Thanks heaps for your help dude. Explained well enough for a primate to understand.
Great job thank you, very well explained
thank you for helping people
Brian thanks so much for this video. Great stuff man!!! Question, I have a 1999 K1500 Suburban. Does it have 2 knock sensors? A friend of mine stated that it only has 1 and it's located underneath the engine...?
Excellent video! I am stoked right now because I just figured my issue out tonight after tons of research and it is the knock sensor! I'm no mechanic but makes me super happy I figured it out! Was just on here looking at some vids so I can listen while I work and this one really has a ton of good info! Thank you!!!
Thanks so much now I understand why truck ran bad after codes or set
Great information for sure.
Well done , thanks !!!!!
Thx man, i was lookn and lookn. I wanted to no y it was given me the code not just how 2 replace the sensor. I like 2 understand y its happening not just replace it. Thanks again
Excellent video!
Hey Brian I had a question. When you said you ruled out the knock sensor on the 5.3 did you mean that it was the problem? Cause I'm having the exact issue on my 5.3 at 70mph that I'm currently trying to diagnose and only can get it to do it at that speed. And also I saw you at the Utah auto expo by the Nissan Titan diesel!!!
In case you are wondering if your car knocks: Get ELM327 BT OBD adapter, Torque App for your smartphone and "Knock Detector" plugin for Torque App.
I've used that. :) It only works if the knock sensor is working. I drove a couple test runs where I knew I'd get knocking. Confirmed the problem. :)
VictoRoy i wish it was the truck i was working on but it was an infiniti and the way to sensors was a whole other beast. Thanks though
Welcome Chris!
Great video
Thanks allot
Does my car have knock sensor
Opel Astra G 2000 1.2CC
amazing Technic to teach ,,,gr8 work
Hey Brian that video was great. I know it’s been a while but would you still have the video about the Silverado. I have an 03 that I changed to KS’s on (used AC Delco ones) because the engine was pinging unless you put 93 octane in it. Now it don’t ping with 87 octane but the MIL is on for “low input”bank 1 &2.
Thank you sir! Very interesting and helpful. :)
any info on sensor placement for instance intake valley versus externally connected to the lower block
Thank you very much. This video helped me.
Reckon I like the way Mandy talks, mmhmm. But seriously, great video! #hard work and effort recognized, thumbs up for sure and as usual!
thank you Erick for you share you video
thanks Brian,
it makes sense
Great video. I wish someone would do one on the two pin wide band sensor. At least I think it's a wide band, it's out of a1989 ford f150 5.0.
your info helped me alot thanks much
Good vid. Lots of info but I respectfully disagree with 2 things... Knock sensors came with fuel deregulation after 1978 when pump gas went from 103 octane premium down to 87 octane regular. Octane level determines gasoline's resistance to detonation. Compression was lowered initially, but much power was lost. Computers and sensors allowed some of that to be reclaimed. Next item- turbo and blower engines are usually LOW static compression. This allows more room in the combustion chamber for a bigger air/fuel charge. Your compression is determined by the speed and ratio of your supercharger or turbo. Your rpm is limited by the fuel's octane and where detonation begins. An engine with higher compression will have less power gain by adding a turbo/blower than a low compression engine. A naturally aspirated engine with 10:1 compression will make more HP on a dyno using 93 octane than it will using 110 octane race gas. Proven fact. Excessive octane slows the rate of combustion and makes less power. Use just enough octane for your compression ratio and no more and you will make more power.
great information in this video thank you
Awesome video!!! Just one question: what does the letter on the bottom of the bolt mean (e.g. "A" and "C")?
Another great video. I had an old s10 with a knock sensor issue and the replacement kept throwing a code, so, without knowing this info, all I knew how to do was bypass it. I never had problems after that, luckily. I prefer to fix things properly though. I'll check out ADP Training and give him a subscribe.
awesome video!!
many thanks for letting us know (best goes to you)
Best explanation ever!!!!!!!!!!!!!!! Make more car videos!!!!!!!!!!!!
Thanks bro and more blessing 👍
