Honestly I have watched 1000s of videos over the years for shade tree mechanics and this is the best how to video out there 🙌
Thanks for posting. I have about 429,668 miles on my 03 Accord EX 4 cyl. I watched several videos before attempting this. It took me less than 8 minutes to complete and saved a lot of $$ doing it myself. I used scotch tape to hold the new sensor in the 27mm socket as I hand-turned it into place. Removed tape from socket then snugged with ratchet. I did unhook the negative from battery in order for the engine light to go out. Runs so much smoother.
Impressive mileage! I’m only at 247,000.
This did the trick on my Accord, would suggest adding extension magnet “thingy” in case you do not use enough tape in the socket or if drops w/ an extension socket.
Thank you for the video!
Just did this job today. Can't believe some people are taking the manifold off. 20 minute job tops. Thanks for Video, it help 😊
Just made this repair on my car following your guide. It went great! Thank you so much! Saved me hundreds in mechanics bills.
Was about to remove IM, until I seen this. Easiest job, was done within 20 min. Thanks
Glad to hear it!
Thank you for making this short yet informative video with very clear instructions. I think I’ll be able to switch this thing out myself now!
Most concise video ever recorded.
By far the best. No jacking car up. No taking that pain in the butt black bottom cover off. Thank you. '03 CRV 245k
I just got the dreaded code on my wife's 02' CR-V. I have been watching different ways to do it. Top vs bottom. I'll try doing it from the top first since I hate going under and removing all those clips. She still runs like a champ at 180k+ miles. Love the CR-V!
Finally, I was wondering if I can access it from the top side. It looks like there's more room at the top, just harder to see, but at least I can see what is involved. Thanks for posting this video! 👍
Thanks! This helped me get rid of the CEL code.
I had to buy the 11" long needle pliers at HF for $5 to remove the plug to the sensor.
A socket extension of 7" or 8" would have been perfect to remove the sensor, my 10" was difficult to use due to interference with the fan.
After screwing on the new sensor, the plug tab was now at the 3 oclock position (not 12 oclock like old one). So it was kinda hard to to plug it back it, but finally managed using just fingertips. No more P0325 code.
I bought the sensor at Adv Auto P for ~$55
Quoted $360 for a $60 part.. literally some blood sweat and tears but I saved $300! Go me.
Thank you bro, this code just popped up for me, and the first video that pops up is the one that helped me.
Thank you very much for making this video. I was able to do this a couple days ago on my son's 2003 Accord. It was challenging, but I got it done following your instructions and techniques.
Hardest part was getting my hand squeezed in to be able to plug the electrical connector back in. I was able to remove it using long needle nose pliers, as you suggested. Also, I had some difficulty getting good lighting in there. But, much easier than removing the intake manifold.
Thanks! Agee, I've done it both ways and this is better than removing the bracket below the intake and all the hoses.
Wow saved me hundreds of dollars! Thank you!
FANTASTIC vid. Thank you for being so clear.
Thx, the first one I watched was a bit more detailed, but yours is great too, thank you.
Just did this on my 03 element. Might be easier to remove intake… but not too bad doing this method. Not as much room under the hood for the element as in this video but was still doable. Hardest part was plugging connector back in on new sensor lol. Took about an hour to do for me. If you don’t like shoving your hands in tight spots with poor visibility take the intake manifold off.
Excellent video!!You know I don't drive a Honda or Acura but enjoy watching videos on repairs..I just want to say you made a very detailed video that is str8 to the point, with the correct steps showing how to do them, in a quick video that isn't strung out over 25 -30 mins with useless banter lol.. So again,very very excellent vid showing people how to diy!!
This is really awesome, gonna help me out, thanks man
Very Good video. Wymiana czujnika spalania stukowego . Honda FRV
Great video man!
Thanks for your video it helped
Couldn't unplug with pliers I was able to grip plug with needle nose pliers then used long screw driver to push down on the clip then pulled with the pliers. couldn't get my hand under manifold to plug back in so i tried to the left of the manifold and had plenty of room to get my hand in not underneath the manifold on the left side hope this helps someone
What do you mean you lifted the manifold? You didn't have to loosen anything?
@@hanginon1293 read it again I didn't take off the manifold my hand was too big to get under so I went through the side of the manifold the left side
@@victorbelmares2722 OK my bad, I read it as lift instead of left. I have to replace this so I'm watching and reading as much as I can. I guess my eyes are getting blurred
@@hanginon1293 no problem
Why u lying @@victorbelmares2722
I wish I saw this video 6 months ago..while it was warm outside! Now I have to do this in the cold! Lol
It's that simple and a shop was going to charge me 1,000 dollars.
Great video thank you so much!
really well done video
Great video, let's see if it works. Thank you.
Thanks, very helpful
Thanks I just use your video and got it complete 💯
Nice!
Thank you
I found this job way easier with a 27mm spanner for removing the sensor and two long flat headed screwdrivers for removing the plug. I also did this from under the car.
My first thought was why plyers except maybe to replace the the plug?
Best VIDEO !!!!
Thank you! Perfect video!
After removing fe de fender plastic I use 2 screw drivers to unplug it, I used a 1/2 “ drive sucket with a 3-8 reducer and short ratchet eventually you will figure out how to get your hands in there
Thank you! It worked :)
Thank you good sir
I have to go back in to replace a 3rd party knock off knock sensor I just installed following this procedure on an '05 Element.
This time I will loosen the intake manifold. It took me a day and a half, 10 hours, of swearing last time.
I expect a 2 hour job today.
Which step did you find to be time consuming or difficult?
@@bokhenik - All of them. It seemed like the old - 'trip over a dollar to save a dime'.
Trying to reach the release tab on the wire plug
2 hours.
Getting the old sensor out
1 hour.
Lining the new sensor up and getting it started
1 hour.
Tightening the sensor to 25 fp
.5 hour, but incomplete*
Getting the plug back on the sensor tab
2 hours - not counting drive time to the parts store to buy a remote grabber tool.
*believe I was just tightening against the swivel, and hoping the sensor is still loose because it didn't fix the P0325. This time I'll back the manifold off to save time and frustration, as well as have space to test the circut.
amazing video, random question! what does the knock sensor do??
It’s senses for any detonation within the cylinders, and then tells the ECM to dial back ignition timing accordingly, often just 1 to 3° at a time.
It’s a very important watchdog for modern engines. In case you have bad gas, or an engine that is in a poor state of tune from lack of maintenance.
Supplemental research:
…google “engine pre-detonation” and “engine knock” for further learning.
✌️ 🔧
Can I do this job with a 3/8 drive instead of a 1/2 drive? If so, would it be possible to recommend me the correct socket?
Thanks in advance
3/8 should be fine. You need a 27mm socket deep enough to clear the plastic connector on the front of the sensor.
This is so helpful I just did this on my element. Additionally helpful tip if you don’t have tape you can use the socket with extension to hand feed the new sensor. Just put piece of printer paper small size just enough for sensor to bind with its install socket. I didn’t have tape lol but this video saved me money
Nice tip! Glad it worked on the Element.
Or 1 1/16th inch if you dont have 27mm socket
Did you use the original Honda knock sensor or one from Amazon?
I used a Beck and Arnley sensor (from Amazon) and it’s still working fine. My first attempt was with a knockoff Honda sensor (eBay) and it had poorly machined threads which almost messed up my engine block. Avoid those.
Knock sensor replaced. P0325 still checking.
Wiring traced and all good.. P0325 still checking.
Anything else to diagnose ??

Aftermarket knock sensors that you buy at the auto parts store are notorious for not working correctly and causing the same codes to reoccur. That's why many people recommend only using original OEM knock sensors. I had this problem on my Lexus with a V-6. I bought two new knock sensors and the associated wiring harness off of eBay but I made sure the parts were original Toyota components that were still sealed in the original bags. Besides buying the parts from a dealer (which will be very expensive) buying OEM parts off of eBay (a lot cheaper) is okay but you have to be very careful about what you are getting.
The old one fell in and i cant locate it. Will it damage anything if i leave it and just install the new one?
I highly doubt it will damage anything. I’d install the new one and see if you can fish out the old one later. Maybe try a magnet.
Neat way to do this but the intake manifolds on these accords are really easy to take apart. They are a 2 piece design. It is more difficult on a crv and element for the radiator fans sit closer to the manifold and do not give you any wiggle room
I found it pretty tedious to remove the manifold when I replaced my starter a few years ago. Even on the Accord it was a bit of a pain to remove the bolts on the bracket below the manifold. Plus technically the gasket should be replaced which adds to the repair cost.
If I had to replace this sensor on the accord again I’d absolutely use my method. I can probably do the whole job in
@@bokhenik Replacing the starter the was of my least favorite things to do on the Accord. But I had the alternator go out a couple of times (cheap auto parts store brand and it's second replacement), and those are much easier to do. I'm needing to replace my knock sensor now, so your video has shown it's doable without too much hassle.
Make sure you get a reputable knock sensor. I’ve heard that knockoff eBay knock sensors have poorly machined threads that can mess up the thread on the block.
Why dont you have any video of you actually removing the sensor connector?
Good idea. I’ll record a video doing this live.
Can the knock sensor also create problem when i start my car. I am having problem starting my honda accord. Can this sensor be the reason?
I don’t think the sensor would cause starting issues. Might be a starter issue in which case you would need to remove the intake
@@bokhenik thanks for the info but i got a rebuilt starter last year i dont think starter would make me that problem.
Do you need to disconnect the batteries?
I didn't as this sensor is not powered when ignition is off. But it may be a good idea a precaution.
What size socket apdator is connected to da 27mm...
1/2 inch
@bokhenik okay cuz I'm in process of tryn to replace mine and it's frustrating me 😤
How has this aftermarket knock sensor held up?
I initially installed an Autozone sensor which lasted about a year. I replaced it with a Beck Arnley and that has been good for 3 years now.
@@bokhenik Good. BA is the one I ordered. Thanks!
DID YOU USE GENUINE SENSOR or After Market?
I used aftermarket. First one broke after one year. Second one is going strong (Beck Arnley).
One more thing, don’t use fake OEM eBay knock sensors. They have poorly machines threads that can mess up the thread on the engine.
Great video....
I don't have a girlfriend so I can't get a mirror.Going to take it to a shop.
I've got wires in the way that I can't get it around
I had engine light on and code read P0325, I disconnected the battery negative for 1 minute and reconnected, everything works normal, no engine light or code come back. Do that before you change the sensor just to be sure.
I did the same but it will just reset and eventually come back on
I had this problem on my car. I found that resetting the code and turning off the check engine light only worked as long as I drove the car under 55 mph. If I tried to drive over 60 mph the light would come back on again. Also, driving the car with a defective knock sensor can damage the engine internally. The computer uses the knock sensor to adjust the ignition timing to eliminate the knock. Without the knock sensor you can have undetected pre-ignition that will eventually damage the engine.
how do you unclip the knock sensor?
Squeeze with pliers
this will not work for a CRV...
Having a hard time removing the connector. Cannot get my hand in there to grab it and securely pull it off.
Did you see my other video on how to remove the connector?
@@bokhenik I did not but I got it and thanks for replying
Much easier to remove the intake manifold to get the job done, and I’m a girl!
I agree 💯%justbremove 45 12m and take bottom bracket loose 12m also pull too side knock sensor sit right there
6 bolts total remove hose and one other bracket screw out and back in
Just remove the intake. By the time this way works. Removal of the manifold makes it a 10 minute process, this way could take hours.
This doesn’t work well at all on a 2006 Accord, for several reasons, just one of which is, on my 2006, there is a large piece of plastic under the intake manifold that prevents you from seeing the sensor. Another is you need a very specific length of needle nose.
I tried to use this method, and wish I had just done it by the remove the intake manifold method. I would have had it done in considerably less time.
As requested, I have uploaded a companion video that shows a more detailed view of unclipping the connector: ruclips.net/video/FdpLhxxOXhg/видео.html
It is easier to remove the intake and then replace the knock sensor , 15 minutes guarantee, remove the intake hose , remove the throttle body , 4 bolts, then 3 bolts for the intake along with 2 nuts, one vacuum hose , that’s it , you don’t need all that hassle, trust me go the easiest way
If you go that route, its better not to remove the throttle body from the intake and just disconnect the intake hose. First time I replaced by knock sensor, I spent an hour cleaning off the throttle body gasket and another hour buying a replacement.
As far as which method is faster, I think it depends on technique. It took me a while the first time but I did it several times to film the video and can do it in ~20 minutes.

Why add the “girlfriend’s mirror” part? 🤔
Means you cant replace the censor if you are single
@@albertangelomorin9345 damn it! That's why I couldn't do it myself.
Hahaha
Hahaha I thought the same thing. I don't have a mirror, great, now I have to get a girlfriend 🙄
Pick, pick, pick.
Completely failed on this task because I did not get a mirror because I do not have a girlfriend.
Also I got big fat hands.
all joking aside. I actually pulled it off. I was able to replace the knock sensor and I felt pretty damn proud being able to do it by myself instead of going to a mechanic. Thank you so much for this handy dandy videos.
The tape trick was super effective.
This S.H.I.T dont work for a acura tsx there is not enough room to fit any kind of pliers uner the manifold
You didn’t show any movement on replacing sensor or clip😡😡😡😡😡😡
I don't have a girlfriend tho
Girlfriend..?
It's not a big deal to remove the intake.
