I will do my best to explain the operation of the knock sensor that is used in most modern vehicles and I will demonstrate on my 2000 Honda Accord how to easily switch one out.
There are many ways to "skin the cat" and these are the methods that I use. Any criticisms or alternate methods posted in the comments are welcome, just keep it civil.

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

@ktecgarage 2 года назад

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!

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.

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.

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...

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.

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 2 года назад

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

@vinlectd4033 Год назад

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

@ktecgarage Год назад

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.

@kristapaul2872 Год назад

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

@ktecgarage Год назад

Cooling fan switch.

@jah-mek-yahtv973 4 месяца назад

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

@ktecgarage 4 месяца назад

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

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 3 месяца назад

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 3 месяца назад

@@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 3 месяца назад

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