The Knock Sensor (KS) senses engine knocking (also known as detonation or pinging) using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM). The ECM uses this signal to retard the ignition timing and protect the engine from this damaging pre-ignition.
Knocking (also knock, detonation, spark knock, pinging or pinking) in spark-ignition internal combustion engines occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
The fuel-air charge is meant to be ignited by the spark plug only, and at a precise point in the piston's stroke. Knock occurs when the peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle. The shock wave creates the characteristic metallic "pinging" sound, and cylinder pressure increases dramatically. Effects of engine knocking range from inconsequential to completely destructive.
Knocking should not be confused with pre-ignition-they are two separate events. However, pre-ignition is usually followed by knocking.
The phenomenon of detonation was first observed and described by Harry Ricardo during experiments carried out between 1916 and 1919 to discover the reason for failures in aircraft engines

Thanks a lot for this video. Followed these steps exactly and repaired my car.
Excellent video! I'm in the process of tearing my V-6 Accord apart to replace the knock sensor and decided to get some tips...I'm glad that paper towel trick works cuz you were shaking that socket and bolt around right above your intake runners...
Thank you, I can continue ripping my car apart with confidence!
😅😅😅
That's one of a kind job....thank you for teaching us to all of us that we don't know that much. But thanks to you I fixed my acura Tl 2005 knock sensor. I 🫡 salute you
2012 Honda Pilot. Was a 27mm for me. Also there is a plastic guide around the wires on the far left preventing getting that last left bolt. Had to remove the two bolts from the steering pump and move over out of the way. Then unbolt and scoot the wire guide out of the way and then I could get that last bolt out. Make sure you have a belt tool beforehand otherwise you will have a fun time getting it back on after putting steering pump back on.
As soon as i open my hood.. yup something was in here.. and yup you called it.. wire chewed.. just need to buy a harness.. thanks for the video
Thank you for this video, that was pretty easy. I will replace mine this spring when I do the valve adjustment. Call it preventative maintenance.
The fasteners you call 10mm are 6mm. The socket is 10mm to remove them. Good job.
Wow keep doing vids sir you are easy to follow.
Can I ask please what were the symptoms of said bad sensor ?
I have to ask I recently purchased an 08 with the J 35 had it only three weeks and I’ve got Yvette codes followed with variable misfires Honda charged me almost $800 for spark plug replacement and an oil sensor bank one sure enough less than 20 miles codes came back now they want another $1600 to replace the entire intake manifold and gasket and hardware just curious please if you could sir what were the symptoms
Great video and very helpful! I'm part way in but there is a plastic piece (like a wire track) by the knock sensor bracket that is blocking removal of the lower manifold bolt. I cant figure out how to remove it. Help!
no need to remove the intake., all you have to do is remove power steering pump and brackets that hold it, you ill need a small 12mm socket to remove power steering pump screws. for the knock sensor use 24mm wrench. plenty of room to reach in once power steering and brackets are out the way.
Yeah if you have tiny little girl hands.
Best video on this i've come across! thank's
Awesome video!!! I followed step by step. Thank you!!!
very good instruction on the knock sensor, I'm going to have to replace mine but did not realized it was berried that deep into the V
do you have recommendation for a good scanner that can read EBS/ brake system faults which I think is on K-bus
Thank you Ur video helped me heaps
I found a crack that leaks coolant on back side above the crossover pipe. JB it?
Whats the approximate time to complete this job? Debating whether I wana do it myself or not. Also mechanics use flat time usually right? Like if it's a 2 hour job, i will likely be charged 6 or whatever flat rate is in the book?
Thank you for making this
Did you need new lower intake runner gasket? Also I heard you can clean the injectors out with brake cleaner while doing this would I have to disconnect each one from the fuel rail to clean or can I spray them clean while they’re still plugged in to the rail
Thank you
I’m very tangle to ripping the intake apart,afraid can’t put is back completely, cause the car is 20 years bolts and nuts might be rusted.😂
Just take your time and you will be ok
I have a question, were is the cam shaft position sensor located on a 2013 honda accord exl v6. I'm having trouble locating it.
My brother needs to do this,he was told there is two knock sensors, ???..curious
On a Honda Acura J Series V6 there is only 1 knock sensor.
Informative vid 👍👍👍
Nice I got this problem knock sensor 2005 accord bugger finding the sensor tho
I don’t know why they bury it in the valley
Would there be a reason my lower intake does not come out so easily? Removed all 3 bolts and two nuts! 🤯
It might be rubbing up against something when it's running I think I had that problem with another hose in my car after the mechanics fixed The car
Is-it a good idea to change the knock sensor when doing valve adjustment?? I will be so close...
No CEL or mouse problem in here. I was thinking if this could be a routine maintenance to do. My 2011 odyssey is 133000 miles on the clock.
Thanks
It’s not a bad idea if your already right there.
I broke mine off. Can I get it off from the side since I have the power steering pump off?
I had my knock sensors replaced on my J series and now have a P0455 Large Evap Leak code. Do you have any reason to believe the install could cause this? My mechanic and I have run all the normal smoke tests and gas cap replacement. Curious is you thought something left or missed from this install could cause this code. Would appreciate any insight. Thanks
Check the lines that plug into the back of the upper intake manifold
Your knock sensor looks different from the one I got at the store that says it's compatible with the exact same 2015 exl v6 honda accord
is there more than one sensor on this vehicle
There are lot of sensors on that car. Or are you talking about more than 1 knock sensor?
@@bundysgarage yes is there more than 1 knock sensor
No just 1
Dios te bendiga gracias
How much torque on the upper intake sir
Just Google it for your specific year make and model and you should see it pop up. Think it’s 16 lbs.-ft but then you will see the sequence as well.
Where’s your garage bud? Need this done on a 2015 acura tlx
That's a whole days work for an unseasoned mechanic. Assuming you don't destroy the engine (or fuel system) in the process.
Dropped the bolts ngl
