How to P0325 Knock sensor replacement Honda DIY

- Tutorial on how to replace a bad knock sensor.
Code P0325 Meaning:
Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged. When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0325 is set, this means that the knock sensor 1 in Bank 1 is not operating properly.
Symptoms:
- Check Engine Light
- Loss of engine power
- No noticeable drivability issues
Causes:
- Faulty knock sensor
- Engine is running excessively lean
- Faulty or damaged knock sensor wiring
- Engine coolant system fault

NO NEED to remove the intake manifold and throttle body. Just remove plastic cover from intake so you can see, then with your left hand set the 27mm socket on the sensor by reaching over the alternator, then with your right hand put a eight inch extension on the socket with ratchet wrench under the intake. As easy as changing a spark plug.
Hi, yes it's possible to remove the sensor without removing the intake manifold but you cannot tight to the correct torque the sensor, which you must do it.
Replace the ratchet with a torque wrench set to the proper setting. Plenty of room to rotate the wrench in front of the manifold because there is an 8' extension. But do it however you wish, I just did this on my son's 2004 Accord without any disassembly of the intake and throttle body. I prefer to advoid needless work.
👍 Good!
@@MrPaulrak wow interesting because a shop is telling me 5 1/2 hours labor to do this at around $600 part included 🤦♂️.
Getting the socket on the knock sensor isn't the problem, disconnecting the plastic connector to the wiring harness without breaking it or the flimsy wire is.
Great video! Easy step by step.
Thanks!
You are welcome 👍
I used to manufacture the Knock sensor Body on a multispindle turning machine in the 1990`s when I worked for TRW :)
That's nice 👍
what do they freakin actually do ??!
@@oglinda8070 I wondered that myself... It's interesting, the engine has a "signature" of vibration and the knock sensor measures those vibrations and the ECU makes adjustments to attempt to match the signature. ruclips.net/video/0xI94ZDF54Y/видео.html
You make it look more dificult than it is,
It took me only 10 min to replace it, no need to disassemble the engine broo
Great job.
Did you tightened with a torque ranch?
@@WhatTube first with the hand then torch ranch, exactly took me 8 min
@@baseball2246 I removed al the intake parts because there's no space for the torque ranch, and it's more clear this way.
All good you took everything out. I'm here to learn how to take out things to reach the starter lol
Can you tell me how you did it?
Where can I find a dash cluster like that
Please leave a LIKE it only takes 1 second.
Thanks very much!
Thank you for posting this video. How long would you say this job took you to complete all in all?
Hi, if I remember correctly was around 3 hours because I had to film as well.
Do you need to use new gaskets on the manifold when reinstalling?
No, you can use the old one, it's not a paper gasket.
Do I need a 27mm deep well socket. My knockout sensor is fine and I don’t want to damage it. I am removing it because I need the space to complete the starter replacement.
Hi,
Yes you'll need a deep socket.
Thanks, I just got everything removed using a deep well.

Hello is possible to change without removing intake manifold? Seen a video using swivel socket with extension
Hi, yes it's possible to remove it with the manifold in place, the issue is that you cannot tighten the new sensor to the correct torque.
What's the torque settings for the sensor and manifold?
Hi,
For the sensor is 31Nm or 22ft lb
For the inlet manifold is 22Nm or 16ft lb
@@WhatTube Thanks for the reply.
I replaced the knock sensor and the light went off but after 1 day usage came back on and again error code P0325, I am getting frustrated, hate to see lights on my dashboard
Try to replace the connector, some time the sensor is good but the connector is bad.
Nope you need an OEM from the junkyard.
Rubberbutthole123 why do you suggest one from the junk yard
@@st3v3nb915 Mr. Rubberbutthole.
You forgot to mention the torque spec.
22 ft lbs

Just done my knock sensor on a Honda step wagon same engine I did from underneath took half hour to replace allways more than 1 way to skin a cat 🐈 🤣
how many pounds of torque pressure?
On this engine is 23 lb ft or 30 Nm.
maybe you can measeure old and new sensor resistance?
Hi, thanks for watching, I'm sorry but I don't have the old one anymore.
How much would this job cost at a repair shop?
It depends where you live and if you choose a local garage or a dealer.
why would you jump to the sensor
Hi, I'm sorry but I didn't understand your question.
Honda Genuine Knock Sensor replaced but Check Engine Light came back on with same code, P0325.
And engine knocking.
Help! What is next?
Plug & wire are good. Honda's spark plugs, coils & valve cover gaskets replaced under PM on 2005 CR-V
Check the engine mounts and the bracket that holds the exhaust pipe near the engine.
If the knock sensor, wire, connector and tightening torque are correct the issue can be in the ECU/ECM itself.
@@WhatTube Engine mounts are still good, bracket holding intake & exhaust are good.
Knock sensor tightened with light coat of anti-seize.
How do you check /or test the ECU /or ECM without overpriced test equipment?
Torque wrench
Replaced with Honda's Knock Sensor.
Drove 600km, code check engine of P0325 came back on.
What is the fix if sensor did not work.
Hi,
When you have the P0325 code on these engine sometimes is just the wiring and connector that need replacing.
@@WhatTube But wire and connector are good.
Hi bro,I have the same issue with my honda crv_2004 model for GCC country.
Did I have to do the same method for it plz let me know thaks.
If you have the same engine then yes is the same method.
I've done mine yesterday and again last week.so put two sensors in it And I've still got the eml light on I have a honda stream with the same engine.. Cant seem to get the light off. I don't have a computer like you but I've reset the ecu by pulling fuse and disconnecting the battery. But after about 5 mins driving the light just comes back on.
Try to replace the connector and the wire that go to the sensor.
Some time the actual sensor is good but the connector is bad.
and have you tighten to the correct torque?
@@WhatTube Iam in progress in ordering a wire and connector. No I didn't know you had to until I watched your video. What torque pressure do you need
If you have the K20A engine it's 31Nm or 22 ft-lb.
@@WhatTube thanks for the info. I don't have that type of tool. I've just tightened it up slightly with socket set wrench. But once I've got a new wire I'll get back to you with the outcome. 👍🏻
@@carpcatcher8193 ok good luck.
you do not need to remove the collector to replace the sensor....
Yes, you can replace it without removing the manifold, but when you have to fit the new one you need to tight it with the correct torque, that's why you need the space for the torque wrench.
What year is this honda?
This one is a 2003, but this engine was installed from 2001 to around 2012.
Important P0325 is the knock sensor code but dont buy a cheap one, or any aftermarket one go to he junkyard and get an OEM TRUST ME
What kind of Honda?
This is a 2 liter K20A Honda engine
6:44
I believe the torque value is 35 psi
I feel yu did way tomuch ,dont post anymore video s🥶💚😈
