Update: Check your compressor tensioner pulley, mine was bouncing and tapping just enough to cause bank 2 to throw the code. I thought it was the compressor but found the pulley issue.
@@MercuryRisingFast I had a sound I couldn’t find turns out one two of my lug nuts where lose but not enough t to come off. But had a tapping sound that got faster as I speed up.
I want to thank you for your video and the visual explanation. I have a Subaru Impreza 120k miles, what I saw in your explanation was a spark plug. I replaced mine first time, the car drives like new now. Thank you again.

"Don't drop them' as you juggle. Bravo, great showmanship. The technical part of your presentation was great too, My Engine Light comes on and I thought it might be the gas cap. So I reseat the gas cap and the light will go away if I drive an hour or so. The light. The light seems like it only comes on every six months or so and then go away. So today when the light came on I went to Autozone to get it checked, and when the guy came out to plug his instrument in the car the check engine light was gone again. But the AutoZone guy plugged in and got historical code of PO327. Since this happens so irregular, does that mean the sensor still works (most times) or could it be a sign of actual knocking, and if so, what would cause the knocking? Bad fuel, plugged fuel filter, ????
Love your guys videos! Barely got these codes last night

I've done this job twice now. First with after market cheap knock sensors. Then I paid top dollar for OEM sensors on my 2005 6L GMC. Knock sensor #2 both times within a day. #2 was slightly corroded but I thought I'd cleaned it up nicely at the very beginning of this job. I used a bit of never seize both times. The OEM ones came in a bag from Amazon. Not protected at all. Thought that was weird. I'll be pulling it apart again next week on days off. First round was over 4 hrs. second was under 2 hrs. So this wont be terrible but it's not a job I enjoy. Very frustrating. I will be using a multimeter on these before I pull them. Thank you very much for this video. Super helpful. Any other advice would be greatly appreciated.
Thank you perfect details you awesome teacher
I've had both of those codes P0327 and P0332 on a 2004 VW Jetta 2.0L. I replaced both sensors and check engine light would come back on sometimes right when I would turn the car on and sometimes before I would drive the car 1 mile. I unplugged both sensors and I checked the voltage and Sensor 1 said 0.00 Volts. Sensor 2 said 1.85V. So right there I knew I had a short somewhere or a bad ground. I just started unwrapping the engine harness last weekend and followed one of the sensor wiring all the way to the ECU, I kept bending the wires and looking for any cuts or corrosion but didn't see anything. Then I put everything together and when I started my car, the P0332 code was gone. Now I'll be messing with the other knock sensor wiring that goes through the injector harness and hopefully I can fix the other code too. If that doesn't fix the P0327 I'll just do new wiring for that sensor cause it's cleary not getting any power. Hopefully this helps someone that can't figure out where their problem is after replacing both knock sensors and check engine light comes back on.
+Adi Shqipe Thanks for the feedback!
Having this issue rn lol replaced both sensors and check engine light is still on
🤔👉 Thank for your professional work with a good explanation 👍 👏 👌 🙌
Very well said pertaining to knock sensors and keep up work 👍
Does the PO332 cover anything else other than the knock sensors? I replaced both sensors and harness and am still getting the PO332 code for bank 2. I test and get 99.8k on the rear 102.3k on the front sensor both good and within specs. Then test the sensors for ac voltage on tap and both are working perfectly. Code pops randomly anywhere from 1 to 5 weeks after clearing the code.
After replacing my knock sensors 3 times in a week my dealer found they had a bad set of knock sensors on they're shelves that GMC had recalled that they didn't know about. Check recalls on your parts yourself, or at least recalls that dealers don't .
Awesome Vid ,BTW does a P0332 cause a lack of power to the engine too
Another good video. I ran a tank of E85 in my 2013 Tahoe.
It is supposed to be compatible. I Think the E85 might have caused the 0332 code.
A FLUKE meter? This guy is a pro! 👍
This test may not work with certain models of knock sensor. For my 2008 G6, the new sensor and old sensor both measured Open Loop from pin-to-pin and there was a range of mVac from each with the standard knock test. I was concerned after watching this video, but when I put in the new sensor, code P0327 cleared, idling smoothed out, and acceleration improved.
What u mean by that sir? I’m a novice so I’m learning
Great, now to just take off the intake manifold...
Is fairly easy
It’s the steps before lol
Well, I had my check engine light come on and read that code of the knocks sensor… i cleared the code… would repeatedly come back on for a period of a few months… until I put super unleaded in the tank, cleared it again and it hasn’t come back on since for several weeks now 👍😎
Thanks for the walkthrough. I always appreciate your concise explanations of the issues.
I have a 2002 Suburban with this PO332 code & am going to delve into the problem.
One thing that you pointed out may help me I/d & perhaps solve this, plus one other issue that I have:.
Every 2-3 months, I get a "Low Coolant" indication on the gauge panel.
When you showed that the Knock Sensor was corroded, that makes me think that I have a slight leak,. maybe originating at the Intake. Perhaps this will help kill2 birds...
And, quite often, I find that an error code is only a symptom of something else, a root problem.
It would be a lot more helpful if the OBDII System was designed to find root problems. But, it is what it is.
Anyway, a BIG Thanks to you guys, again.

I replaced both knocking sensors on my 2005 Yukon XL last weekend and yesterday the codes came back on is there any explanation?
I actually like this guy way better than the other guys for some weird reason. Maybe it's because he can juggle.... that's probably the only reason why.
Thanks for the tip👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

YOU GUYS HAVE TO BE KIDDING ME!!! I have already replaced these once in my truck. One went bad and then I had to do it AGAIN!!! I understand mistakes or defects happen but here’s the cherry on top. The one I replaced twice went bad AGAIN, and so did the other one I replaced the first time. This is bs I’m beyond pissed rn. Gotta waste another afternoon!!! This was my first time buying from 1AAuto and this is how it went. Unbelievable.
Gotta get Ac Delco sensors buddy
Thanks!
I habexa question as to the o2 sensor on my 2002 chevy express conversion van 1500. Has the 5.7 liter motor. I did test at autozone, and it said my bank 2 sensor 1 was bad , didn't have electric or something like that, so I got one and they told me it was the one on passengers side b4 the converter. After replacing it with new one it still says same thing. Any info would be greatly appreciated. I hope I put it on right one, they said passenger side b4 the converter. Thank you and God bless
Good to know, Thanks again

Thanks for the video, I have a 01 Subaru outback and I have a knock sensor code 327, I’ve replaced the knock sensor twice now with Sensors from other Subarus that I know are good, so , when I tested for power going to the knock sensor, there is none, should there be power going to the sensor if so, how much power ? Information appreciated. Thanks, Ron
Hi
I have 2003 yukon xl 2500 6.0L.
I encountered some problems and fixed them, but I have a problem for which I do not know the solution p0327, p0332, p0135, p0300. I changed the first and second knock sensors with the wiring harness, but 02 sensor I haven't changed it yet, and I cleared the codes, and with a test drive on RPM 2500 to 3000 (check engine) and after checking it showed p0327 p0332 p0135 p0300
I have toyota 1994 v6 4runner i want to know if the cables that are connected to the knock sensor has to have spark?
Good morning pal . I have a question , what knock sensor have to do to alternator not charging properly? I'm working on a 2005 Honda Accord 2.4L alt. Charge but when I press the idle pedal stop charging properly 😞
Can this also cause issues to the smog air pump monitor to not complete?
So as long as I use the correct gas I should be ok driving it until I get it repaired? I have the low imput code. My harness I need for my 02 Exterra was discontinued....
Neat!! thanks for these tips.

Hey thanks for de video. Wich is the tightening torque for the knock sensor?
My 2004 avalanche 1500 seems to have power loss and has 2 codes. P0332 and P0446. would either one of these issues be causing my power loss?
Question if you don't mind I have replaced mine 2 times. Still saying rear knock sensor low voltage. And suggestions
I am working on an 08 F 150, it has a newer Jasper engine. I what I think (pretty sure) is the beginning of a rod knock. It is flagging a #3 & #4 missfire. has no power I am thinking the knock sensors are seeing the rod knock and pulling back timing. My question is what does the scan tool reading mean? I am seeing 232s and under full power I see between 900 and 1100. I throu/the scanner on another F 150 that ran correctly, I saw 232 at idle and at WOT I saw 1900 to 2100. What kind of numbers should I see if the knock sensors are seeing a knock?
Just bought a 2016 focus rs, first day I had it, got this code. Warranty covered the replacement. A day after I got it back. Check engine light came back. I don't know what to do. Did I just waste 40k?
so i replaced both knock sensors and the wiring harness, for 2 days i drove it no problem, then one day one of my sensor bank one comes on under normal driving espically if its hot outside and i am running e 3 spark plugs with 87 octance? have any advice whats going on? also i am running a tuner with 87 octane and ocassionally i will unplug it and the light still comes on?
question, i replace both knock sensor and the wire for the conectors chevy express 2004 but Still low input , and the van vibrates when i hit the 55mph , what should i check ,
I have 2 codes of P0327 2 codes of P0332 and codes of P0157 and I think a little less power.
But the engine idles smooth an I just found the PCV valve was stuck open and the wrong one.
What are your thoughts?
Guys i have 02 gmc sierra .replaced 2 knock sensors.. but valley pan small hole.. can i still use same cover?

I just had this code on a Honda pilot the other day, they don't like aftermarket knock sensors😱
I have a 2006 chevy tahoe just replaced the knock sensor and I'm getting low voltage code please help
I replaced them both & now i have a bank 2 low circuit but codes were not there before replacing does that mean it is bad knock sensore
I changed both knock Sensors. And two months later the code pops up again I don’t know what to do but it does have a spark knock So I don’t know if the spark knock is triggering it I don’t know
What happens when you replace the sensors TWICE, both times with GM sensors, and it keeps throwing the code? 😭
Hi. Can P0328 be caused by a fuse or relay malfunction?

How many volts does a knock sensor require to work correctly? Please,
I know this video is old, But when I took my car in for inspection it failed do to code P0332.I have no check engine light on and there's no knocking.I hope when I take it too the shop everything will be ok afterwards.
Nice video, and good juggling.
+David Snyderman Thanks for checking us out! 1AAuto.com
Just wondered if these codes are the same as code PO328??
Now I know! Thx
+TheThreeLeggedChair Thanks for checking us out! 1AAuto.com
What happens when you replace the knock sensors and wires, and after 2 months I had the same code again?
DONT MAKE THIS MISTAKE!Not all knock sensors work but you tapping near it also depend how many hertz (hz) are required for that sensor to produce a/c voltage.newer cars take 6,000hz meaning 6,000 taps per second.not gonna happen .the right solution is to make car run lean(create a knock ) then check output using a scanner.
I got p0332 about a few months ago replaced my knock sensors after no check engine light for those months I got p0327 now 🙃 what else could it be?
I like Your smail 🤠

I have a 2007 silverado classic 1500 4x2 4.8 L. Both knock sensors and harness have been changed. Using 87 octane fuel. I am still getting the P0332 code. It seems that the code triggers some type of guardian mode on the motor because I lose power. Any recommendations???? Please help.

Can a bad knock sensor cause engine damage? I hear mixed answers
Replaced both sensors,wire harness and still getting codes on 04 Silverado 2500 hd truck runs fine no knocking in the motor why am I getting codes
Will a knock sensor on for years former owner foul the spark plugs and leave engine wet sparks over fueling. Anyone know !? Thanks
Thanks much? One question why does my 2003 Chevy suburban have 2 knocks sensors? And why doesn't the good one keep advancing the spark
Bought the parts from you installed them now still getting the same codes
So what’s it mean if I just replaced them but still get the same code?
Thanks for the tips. So what are the chances of both Sensors going bad at the same moment? seems like it could be another related (Electrical) issue. Thanks
Best to replace both on this engine model as to not pull the intake manifold again anytime soon after the other one possibly failing.
So is it worth replacing does it even cause any damage or just one of those check engine lights to ignore
My 04 Silverado does the same thing. Did you happen to figure out the problem? I’m thinking about ground wire I just replaced both sensors and wires and got both sensor codes then revved Rpms to 5k twice then the sensor codes went away drive 50 miles and now bank 1 low input code and no evap code. I’m puzzled
Is there a way to ohm the sensors without removing the intake to see if they are within spec ?
you can test from the wire connecter to the knock sensors.
You also could have a leaky intake manifold gasket giving you a false reading as happened to me replaced gasket and everything cleared up 370,000k on engine

I have a 2006 Chevy Avalanche I'm having that problem is the truck still drivable
It's best to replace it soon because the information from the knock sensor feeds the computer information as how to maximize engine combustion efficiency by either advancing or retarding the timing.
The part is generally cheap and you should be able to find someone on TH-cam that's replaced one on your car make/model. The code may be able to get cleared after installing at the nearest auto parts supply shop.
I replace the knock sensor and still have the code with low voltage input bank 1
So I have a question, just got the knock sensors replaced by the dealership in my 04 Silverado, but about 150 miles later it threw the P0332 code, is it possible that the dealer did something wrong or are the sensors fine and there is something else wrong?

Which year is the car?
What kind of problems can this cuase if not changed.
Other than a knock sound on the engine
Did you ever find out? Not sure if I should fix immediately given the holidays
@@matteobravo2149 my mechanic of 19 years said "Of all my years of fixing cars, I've only had to change the knock sensor once... and that's when I was first starting out."
After he told me this, I left my check engine light on and never changed the sensor. Now 2 months later, I'm still driving well. 👍🏾
Yeah but your car is running on borrowed time and the more you delay the fix, the more damage you engine will sustain.
Your Engine may blow out afer a few months or after 4 years, it's a gamble. And It isnt a quick blow out either: it slowly accumulates permanent damage, becoming louder and worse performing, before eventually dying completely.
If you intend to keep your car for longer than a year I suggest you change it. In any case it' s cheaper than an engine rebuild.

You figure it out? Sometimes a poor performing throttle body or bad grounds can throw some weird codes. Check and clean your grounds or for any loose/disconnected wiring. Verify fuses too because a shorted wire would cause those to go as well. Please let us all know what you found. Hopefully you got it up and running by now.
