What exactly is a knock sensor?

[@jsimmons3090]

sad u sold ur accord. u and your videos helped me rebuild the F23a1 motor in mine. you are appreciated..

[@ktecgarage]

Was kind of sad. The end of an era for me, really. Had it for 10 years and literally put blood and sweat into it. A young father purchased it and I'm glad that he now has a reliable ride. Thank you for the kind comment!

[@michaelmilton8925]

Your tutorials are incredible. I rebuilt my f22a1 with your how to. Finally bought factory manual , for start up fine tune procedure/wiring diagrams. I've moved on with another vehicle B18a1.

[@ktecgarage]

Thank you! The cool thing about these Hondas is that there isn't a giant learning curve working between the B, D, H or F series platforms other than the twin and single cams.

​@@ktecgarage hey I'm about to put a timing belt and water pump on my accord. I'm gonna use your videos I just found your chanel and love the rebuild video I watched so far... I'm doing the rear main now just got the tranny dropped once that's done I'm going to the front side...

[@matthewstone5429]

Best videos on KZbin. Rebuilt my f22a4 with your help. TOTALLY AWESOME!!!!

[@ktecgarage]

I'm glad to hear the series was helpful. Thank you!

[@TonyHustonATL]

Great explanation

[@ktecgarage]

Glad it was helpful!

I took my car to a muffler shop in Chicago because I had my check engine light on...They told me that I needed a new "knock sensor" ... They said they do not work on those. I have to take my car to a mechanic. I thought to myself...I thought you guys were mechanics.

there just welders, do it yourself

[@bmw-e30]

Well explained. Wondering how older engines compensated when they do not have a knock sensor to inform the computer to make adjustments. I recently changed a knock sensor on an Audi which solved the sluggish acceleration but the mechanic warned me that while the code reader showed a knock sensor fault, the problem could be something else like a faulty coil but luckily this was not the case.

[@ktecgarage]

I don't think they did anything to compensate. I remember having a new CR-X back in the day and it pinged like crazy on 87 octane. Thanks for the comment!

[@tammyrnwright3603]

Very helpful! Thank you

You're welcome!

Thank you for let her put on the main media of what reading 😊

[@vinlectd4033]

Can I install a knock sensor on a honda block that doesn't have one? And where on the engine are alternative spots?

[@ktecgarage]

Maybe??? Honda puts them under the intake, so maybe you can find an unused mounting point and tap it to fit. I'm assuming you have a PCM that can read the signal and retard the timing.

[@mrj9881]

where did you buy the rebuild parts or kit for the f23 your working on? I have a f23a5 (dx) that is burning alot of oil and getting ready to rebuild with some friends of mine.

[@ktecgarage]

Company named Evergreen Engine. I purchased their f23a1 kit from Amazon. Try eBay Motors as well.

[@terrythomas790]

Hi, Thanks I have a '02 Acura RSX, with the 3025 code, and 1457, which is emissions. Is it possible these inter related? And with a new sensor, Do you just use the factory replacement$$ or if an aftermarket one is OK, I see an aftermarket with a 3 yr replacement warranty. My local mechanic say aftermarket ok.?? Thanks

[@ktecgarage]

I had an aftermarket knock sensor that only lasted a year. OEM is usually best, but if you have a warranty and don't mind swapping it out, you should be fine. P1457 is a problem with the gas tank evap system and I don't see how that could be related.

[@terrythomas790]

@@ktecgarage Ok thanks! Both problems came up at around the same time, and thats why I asked. Actually I was hoping it was related lol Swapping the sensor it will require me to remove the intake manifold. I just put a new starter last year , and removed the manifold then to get to it. I used a new gasket as well then. Do I need to replace that as well , again? Just wanting to order everything together. Thanks!!

[@ktecgarage]

Ah. K series. If I did it myself, I'd try to reuse the gasket. The right thing to do is replace it.

[@jah-mek-yahtv973]

What would happen if the Valve adjustment gap is slightly too tight on any cylinder? Would that cause a knock?

[@ktecgarage]

Depending on whether it's is the intake or exhaust valve, it might cause backfires and/or misfires. Not sure about pre-ignition.

[@waverider5751]

Usually if you go too tight on the exhaust valves, they have a chance of not fully seating on the face, and this will overheat the valves that aren’t fully closing.

[@kristapaul2872]

What sensor is under the distributor cap on the block of 2001 2.3honds

[@ktecgarage]

Cooling fan switch.

[@ktecgarage]

It the check engine light on for anything else?

[@celli351]

What is the ohm reading supposed to be when testing this knock sensor?

[@AmberHillman-rn8fu]

Aclu mechanic watch out have her put you on the main media so they can find

[@EliasRizk53]

What if we drive without it

[@ktecgarage]

It will mess up your fuel economy and have lackluster acceleration.

[@steveiliev8912]

Be aware! There are a lot of knock offs amongst the knock sensors!

[@cgoldy45]

I took out my throttlebody and pleum off and cleaned it put everything back together now car is running at high rpm its over 3,000

[@ktecgarage]

Throttle cable not adjusted right or a vacuum leak would be my 1st thoughts. Make sure you didn't miss a hose.

[@cgoldy45]

@@ktecgarage if was idling high with cables on and off

[@ktecgarage]

Ok. If it was idling normally before, then I would bet on a vacuum leak somewhere.

[@forgetaboutitwillya.2981]

No! The accord is gone. Lol

[@ktecgarage]

Say it ain't so! 😆

[@forgetaboutitwillya.2981]

@@ktecgarage I hope you never take down the f23 rebuilt videos. I'm currently using them to rebuild my motor!

No worries. Never happen. Good luck with your project!
