- WARNING!!! You must properly torque replacement knock sensors or you may experience a return code and sensor failure. Watch this supplemental video for additional critical information: • GM Chevy P0332 P0327 S...
Do you have a 1999-2007 Chevy Silverado, Tahoe, Suburban GMC Sierra or Yukon equipped with a 4.8, 5.3 or 6.0 Liter LS series engine and are experiencing an illuminated check engine lamp, a stored code P0332 and/or P0327 accompanied by spark knock? Watch this video for more information. - แนวปฏิบัติและการใช้ชีวิต
Knock sensors are also named that way because your knuckles knock against everything while trying to get at them! LOL Great advice / info!
knock knock. whos there? Mr Knuckles. hehe
Thomas EXOVCDS any leads on how to do the 01 4.3?
Had this on my 01 Silverado. It runs fine and I am getting the best mileage since I've owned it. I'm not touching anything unless it starts having problems, but it's been about 1500 miles with no issues. We'll see.
The best auto repair video on the web!
Because we are broken, doesn't make it not fixable! Keep them coming
I'm knocking my head on this one. I replaced my 2006 sierra knock sensors with cheap aftermarket parts, failed within 100 miles. Replaced again with OEM sensors and harness, same outcome.
What I'm I doing wrong? Torqued properly, wire harness has continuity. Your channel is great!
Truck at operating temp bring rpm’s up to 5k for 5secs twice after replacement and code clearing
Thanks, man. Your head's definitely broken. Hoping this will work better than going to N.A. meetings for me! Also appreciate the concise, informative instructions. haha
Probably should stick with the NA meetings but watching my channel may help as well. Take care brother!
Quick tip for the rust belt guys. My sensor upon removal actually separated into two pieces leaving the base in the intake valley and the top part and inter workings all over. I thought I would never get it out easily. I took the same size socket 23mm iirc and jb welded it into the piece that was remaining in the intake valley. When that dried I was able to back it out.
Great tip! Thanks for watching.
can you just unplug the wire /@@ThecardoctorTV

Sitting in my office checking out your video on knock sensor, thanks for the info.... The video helped me by saving time trying to locate them, thanks a bunch car doctor..... crazy dave
I think the South Main Auto Repair Channel is therapeutic also haha
+South Main Auto Repair SMA is the bomb!
ivan eric o and the car doctor this could be a syndicated show for up and coming techs
ivan eric o and the car doctor this could be a syndicated show for up and coming techs
Indeed!
Showing the actual repair would have been nice
We listen to all of you guys that have the auto mechanic videos! Only because the dealership doesn’t do videos 😂 😂 😂 we still Love y’all!
Thanks man! All the info you need in one location Love it!
I had a major vacuum leak at my intake gaskets on my 02 Chevy 4.8 and decided hey why not change knock sensors while I had it apart. Got the Dorman kit which comes with 2 new sensors and harness. Well a couple hundred miles later and I have a p0327. Super frustrating! Definitely don't buy Dorman!!! I should have left the old ones. Lol.
The tracer vision your camera has is pretty sweet!
thats why i love mechanics i could never fix myself but i can fix stuff lol
I just had mine come on P0 332 just a couple of days after I cleaned and degreased my motor. I hope the moisture didn’t screw it up from that.
I'm having this problem now. I did not find out until my 99 Camaro SS failed inspection, The thing is I never got a check engine light or anything else.
But what issue do these going bad actually cause. Thats what i cant tell. Mine runs and drives great but is throwing codes.
Your intro made me laugh. Nice work! haha
thank you very much Dr .
Hey Tim you must be working on a Chevy pulled out of the swamp or something. Been driving Chevy 's for 40 years and never had as many problems as this truck. I guess it's a demonstration vehicle to learn from for defects found to help Honda and Toyota owners :)
Steve Rob The truck was donated to a local Christian school and has a little over 160K miles on it. I have completed over 3K in repairs so far and still have a couple leaking exhaust manifolds with broken off bolts in the head. Going to defer that repair until it becomes a real problem. Was going to do a water pump video on it but the footage didn't turn out. Also it sounds like a fuel pump is not far in its future. I do have a couple more videos from this project to post and they should be up this weekend. Just doing my part to promote Toyota sales across the globe!
Ha Ha - yeah I have the sheared off exhaust bolts as well , not leaking its been 4 years like that. The fuel pump never went out but I put a new one in a AC delco at 90k because it was just a squealing high pitch noise, changed at 140k because again the noise, I have a carter in it now and it's real quiet I have 270k on now. If you do the exhaust manifold I'd love to see that. That's great helping out the church. Bless you. 👍
I got this code on my 04 avalanche. My truck is running fine but the light came on while driving on the freeway. I bought thr part from oreilly, is this something i can tackle In a weekend? I've worked on my truck before so I have a little bit of knowledge on it
Thank God this is not the way my 1999 Suburban is set up, it has the 5.7. I had the P0327 code. One sensor behind the starter and I was done. When the KS went bad I also got the P0420 code. It must have really loaded up the exhaust when it went bad. I almost crapped my pants thinking I had to do all that work.
Were is bank 2 knock sensor 2 on a 2008 Chevy tahoe
I replaced all 3 parts with aftermarket crap a yr ago and now I have both codes again even though the knock sensors still look new. So I’ll buy the oem parts
I have a 2004 Chevy Silverado we have replaced the knock sensors and the wiring harness and the valve cover gaskets with GM two days later the light comes on and still says knock sensors went back in the shop had the parts warranty doubt replaced again same thing keeps on recut Rica Corrine what else could it be I'm at my wit's end I would like to get my truck going again and enjoy it I've had it rebuilt from the ground up and had it customized and since I've got it out of the body shop this has been an ongoing problem
We should sit and chat. Hahaha. Nice intro fella
We did us AC Delco parts and my L33 5.3L still throwing knock sensors codes and YES my brother is atleast a 30 year mechanic! I'm about to just bypass it! I can burn rubber, low on power & there's some days I pull out into traffic and it doesn't good it's like someone is pushing it, then it just seems to wake up out of the blue. There are times that it runs like a raped ape! On another note have you ever heard the hour meter reset itself? Thanks for taking a look at my note!
Listening to your videos and looking at your bald head is mesmerizing , but at the end of one I feel hypnotized to believe I can fix any automotive problem.🤪😳😁
I have knock sensor code and I am thinking the knock sensors and woring harnes was replaced because I bought parts and observed the top end off and seen holes where sensors go..no audible of which you speak was present..but I now have the code still..not sure why was suggested to me throttle body and or mass MAS may need cleaning
Where is the knock sensor on a 2012 Chevrolet Silverado 4.3 V6?
I like your personality. Try to spend a little more time with a step by step and I think it would work out really well for you.
Thanks!
So glad I have a 8.1 in my 2002 2500hd my knock sensors are right on the underside of the block right in the open where you can get to them 😎
awesome video 😊
Thanks for ur video! Now i know where the problem is. 👍
what if you simply clear this code and continue driving? I have a 2003 Suburban with 220,000 miles...sounds like if you can't do this yourself, it'll be labor-cost-intensive...I've seen the check engine light on for about 3 weeks, just got a code reader, and this is the code...P0327...please advise...and thank you for the excellent video!
You can clear the code and if it stays off then I wouldn't worry about it. If it comes back then youll know what to do. Thanks for watching!
Thanks you very informative.
Will washing out the engine bay possibly cause the bad knock sensor? I swear right after I had my 03 Yukon detailed the check engine light turned on and this code poped up!
My experience exactly! I have a 2001 Sierra C3, sprayed some Simple Green and rinsed, then blew dry with a leaf blower. Check Engine came on shortly after and diagnosed with P0332 code.
So this is an old video I was looking because after getting code P 0332 I replaced my knock sensors and harness with aftermarket parts. Code came back. I than took the intake off again and replaced the Knock sensors with AC Delco sensors and a harness. Code came back. I opened up the wiring harness traced the wires from the plug back to the ECM and I removed the pins cleaned and ran new wire. I testes the wire hooked it up and started the truck. The code was gone. Put the truck all back together and since I live in Pennsylvania I need an emissions test. And since I cleared out the memory I need to drive the truck about 100 miles. All went good for the first 5 minutes then the code came back. Now what??
I replaced both knock sensors a couple weeks ago now I have this code.
I've also just replaced both sensors along with the harness... all gm ac Delco and I have the same code popping up... I deleted and comes back...smh
@@gerardoesparza8650 What did you end up doing?
What did you end up doing?
@@colerichardson1746 i replaced them with gm ac delco knock sensors, also the plug and made sure the area was clean and dry. The code went away.
What a stupid location. What was Gm thinking?
Gracias por su video Amigo!!!
i was hoping to see a lil of how u took out the part over it but dang
I just got a code for bad knock sensors. But will faulty sensors make my idle and shifting act funny in an automatic? It’s a 6.0 Vortex Max
Yes
Hi i did my intake gasket valley pan gaskets for a leak i replaced my knock sensors just cause i had to remove them i had no code prior once done now i have a code for the sensors replaced with ac delco wth any idea
I have a 02 silverado 5.3 i changed the mass airflow sensor an its still doing the samr when u plug it up it tries to stall an u cant drive it but if u unplug it it runs better an is drveable i have bern told several diff things. When its on the scanner it only shows misdfire cylinder 7 but i have changed the coil wire an plug i was told it is n the fuel system
My son replace BOLTH knock sensors and wiring harnesses built the dam with silicone cleared codes with my AUTEL unit. 2 days later it's throwing PO327 any ideas?
I just replaced both of them and the wire hardness and both codes came back on any advice
Did you ever resolve that problem? Same thing happened to me
please can you show me where are the knock senor of 1999 chevrolet express 2500 cargo van
I have p0327 code
Just replaced my knock sensor 2003 yukon xl ... about a month ago but my check engine lite came on and indicates that its that same sensor .any ideas why?
how long do these last? I just did this 2 years ago, and I'm getting the code again
You Are Correct Sir!
Car doctor I'm having time w/ an 07 u still active here ??
does this video pertain to a 2005 chevrolet tahoe?
Any idea where the knock sensors would be on a 2005 Pontiac Montana SV6 3.5L?
Can you out grease on the threads of knock sensors if so what happens
I replaced my knock sensors with aftermarket sensors and wire harness, within 2 weeks the error code returned. I blamed it on the aftermarket parts and replaced them with OEM parts.
Another 2 weeks passed and the error returned again. Any advice?
I have the same issue right now
I just got this on my 2005 Chevy Silverado 2500 hd. Will replacing fix my code
Broken people NEED Christ Jesus.
Thanks for the auto tips.
p0332 is in my truck but i been driving it without coolant idk if that cause it or is the sensor suggestions
Have a 2007 Avalanche.. P0332 just came on out of no where... Use OnStar diagnostic and thats the code they gave me. Car is running smoothly, no knocking.. I was wondering maybe if it was bad gas, as i have about an 1/8th of a tank left..
+Josh Stern If in the outside chance it was somehow related the light should go away after a while driving on a fresh tank but I wouldn't hold my breath. Sometimes you wont hear engine knock either. I would play it by ear and see what happens or do some of the simple testing like measure resistance at the sensor connector. Good luck!
+The Car Doctor I will keep you posted.. thanks for the reply !
Thank you for dropping by the shop. Blessings.
Hey car doc. Where is the knock sensor located on a 2010 Chevy equinox?..
It's actually in the front of the engine. Not inside. Replaced mine a few weeks ago from under my car.
Mr Doc I replace my knock sensors not the cable but I also put high performance coil pack that was all no extra wires to that and it's calling out the knock sensor could the coil pack high performance be the problem if I didn't upgrade the wires to those as well it also calls out Bank 1 Bank 2 second O2 sensors and misfire
I’m getting something did u fix it
ive got an oil leak coming from the rear of the engine. going to tackle this and was wondering if there is a gasket under the valley pan where those knock sensors mount to.
Don Ammon there is a green clip on gasket underneath. ideal to replace while you are in there.
Are these intakes and knock sensor placements different on the LS4 5.3lt in the Pontiac grand Prix GXP's? I have to do knock sensors on my 06. And I'm wondering which gaskets I should also order ahead of time.
Hi. Is the bank one sensor at the front of the engine ?
How much would you charge for the labor sir what’s a good price for good work of course?
All depends on your location. I’m in Alaska. Alaska is super expensive.
Hey body I change the my knock sensors and plug on my 05 gmc yukon just like a week ago light came off after I install it but just turn back again giving me same code p0332 and p0327 any ideas?
Harness Ground problem if you get both, or possibly bad leads to and from. But alot less likely
Good video. Thanks!
+jimy taylor Thank you for watching!
I replaced mine with GM sensors but, in a time crunch, used a Doorman harness. Don’t use a Doorman harness. Code still pops up.
Oh crud. Also make sure to properly torque the sensors to avoid return codes. Sorry about your problems, hope it gets better
I have got a 2001 1500hd with 6.0 engine , keeps throwing po332 and po327 codes , I have installed three different knock sensors , still get codes , replaced the wire harness twice , and yes I'm using GM harness and acdelco sensors ,
what can I do to trouble shoot this , any tips , and yes I torqued the sensors down to 15 ft lbs each time ,
have you ever put a 100 ohm resistor inline for the knock sensor ?
never tried that. Is there an engine knock? Might need to measure resistance all the way to the PCM connector
i have and it all checks out good ,
do you know what measurement the pcm is looking for when it test the KS , ?
I do understand that the resistor in the KS is for the voltage drop coming from the pcm , so is the pcm looking for resistance or ac volts in a specific range ?
Mount them on outside
I'm just a little confused on your video every video I've seen was not this labor intense to replace it.... In the park is like a $35 part from an auto parts store and you go up from the bottom to replace so I guess I'm just a little confused... Yes I only Chevy Cobalt that's been diagnosed with a faulty knock sensor
do you happen to know where the knock sensor is located on the 4.3L? My 02 S10 is giving me PO327, the truck runs just fine, great actually. I just want change the sensor but I am having a hard time finding it.Maybe its under the intake manafold...
Thanks
Austin Butler the knock sensor on your vehicle is located just behind the distributor toward the left rear of the cylinder head. It has a three wire connector that is squeezed to release then a hex socket is used to remove the sensor. Be careful not to drop the replacement sensor. Good luck and thanks for watching.
Would thus go the same for a 2001 chevy blazer
Hi Doc, as usual excellent very informative video. Doc i have 4.3L 01Sierra i could not locate the knock sensor. it uses GM part number (21024981) and it is installed externally but i don't know where. Appreciate if you could help.
Under the distributor. Have to remove dist I believe
Replaced sensors TWICE. Both times with GM parts. Still getting code. 😭
So am I, about to take it on a 800 mile trip to Vegas. Did you still have the problem or did you find the fix
@@iWubzies I haven’t had time to take it back to the shop, but I’ve driven it 2000 miles for work over the past month and it didn’t affect the truck at all. It’s just a light. I am, however, dropping it off next week to hopefully finally get them to figure out what’s wrong.
I replaced knok sensors still throwin code any ideas?
$$$$$$ for reparation change sensor??
hey car dr. my name is Dion i have a 2002 Avalanche 1500.5.3lt it cranks starts but shuts down after 2 sec. or so.i hear the fuel pump start build pressure not sure how much.waiting to get my hands on a tester to cheçk pressure.the security light stays on when key is in off pos.sure could use some help.ï
Dion Filler. If ur security light stays on. That would be the gm pass lock system. It shuts down the fuel pump. U can still hear it but won't send fuel. U happen to use a different key then the original? That's usually the main cause.
could this cause hesitation in first gear when accelerating?
+swan734 for sure! Do you have the code? It effects timing control so power on accelleration is totally effected. Thanks for tuning in.
The Car Doctor I have this code and noticed mainly going uphill I get a bog for a second or so. Any long term issue to worry about since I can’t throw another dollar into this truck for a few weeks.
Joe Max Fpv did you find the issue my truck is doing the same thing
@@JoeMaxFpv what ended up being the issue? I have the same symptom . Feels hesitant going up a slight hill around 55-60. Changed both sensors 2wice now. New harness. Im bout over it lol
you could have some great videos if they were longer like eric o's at south main auto. takes us through the diag! but good work
+phil holbrook Thank you. Eric is sexy and that's why people like his videos. Haha
+The Car Doctor PS- I'm the one who convinced Eric to start making videos in the first place. He's a super smart guy. Sexy and smart.
I Was wondering does these share same two part # i has 2001 silverado 2500hd w/6.0Lt my lite been on cleared lots since past 6+ yrs i was kinda hoping lite burn out lol so im going to fix it put it off too long clearing codes lasting few days now i see where there at i think ill be able to do it now i seen ur video .thanks 4 sharing i would had never guess there was stuff under intake and not knowing there was two of them i look b4 now i see how i missed them there buried in real good
I suggest using GM parts (gaskets, sensors, harness) to avoid having to do it twice. Also don't drop the sensors or they may get damaged. Go for it! You'll be glad you did. Besides that you want that light to go out so when the MAF goes bad it will come back on and you'll know there's a new problem that needs addressed. Haha.
my heavy Chevy gets all oem parts they fit not waste time try making them cheap junk parts fit or end up going bad in short time and at end of the day its worth $$ u spend then breaking down pay some one else ton $ to do job u could do on weekend or should had done in 1st place i been there done that trying to get cheap cut corners now i got my dream truck i try to keep this one 100% oem i rather pay more but i dont has 2nd guess it if i want to make 10 mile trip get milk or 1000+ miles trip old girl get me down & back i had truck at 3 shop they made it out to be hard job they said i had to drop off few days not me i dont have 2nd ride sit around just sit at a shop when its few hr task not few days job lol ill order those parts hope it fixes no other curve ball comes out wood work my bad luck i would be surprise i get more codes after time will tell i wont no how act if that little lite not on i think it just burnt out wont pop up when there is real issue thanks 4 help on video and with needed part list
sounds good. Hope it goes well!
No SES light nut I have an apparent Spark Knock. Could it be a bad Knock Sensor and not thrown code?
+troymassey90 Yes, if you can monitor the knock PID and it does not indicate knock when you hear an audible knock or when a light hammer tap on block near sensor then its likely a bad sensor or wiring.
hey car doctor how hard is it to do it ur self I want to do I but on a scale from 1 to 10 how hard is it
Depending on your skill level its not too bad. If you give yourself a few hours and have the right tools and information its fairly easy. Be sure to properly torque the knock sensors after installing!
When you change the knock sensor you recomend change the gasket intake?
he picky about who he respond to
what causes the censors to go bad most of the time ?
BLOODSHOT FILMS Actually most failures are caused by water sitting in the wells and subsequent corrosion and breakdown of electrical connections. Thanks for watching.
do you where the know where the knock sensor is on a 2000 silverado 1500 4.3 v6 engine?
+Geovanny Cota L Rear of engine at corner of intake and cylinder head.
Hello my dear friend .. How are you .. My car is Yukon 05 I have a problem with Knock sensor .. I changed it twice and the same problem exists .. the knock sensor harness not original .. Do you think it is the problem?
Improper torque of sensor
@@ThecardoctorTV Do you advise me to change the knock sensor harness to the original Gm ??
This 2 codes could be root my 02 silverado truck triggered the p0430 , which is bad catalistyc bank number 2 ? Thank u .
+David Arceo I doubt it. You probably just have a bad cat. I usually replace the entire y-pipe.
The reason there staring at uuuuu is there negative brain power is drawing from your high voltage .
I have a 04 suburban I replaced the knocks and all but light still on and same code do you have any idea what it can be
+Ernie Rangel GM parts? Wiring harness also? Possibly someone dropped the new sensor. They are fragile. Any engine noise? Did you test the circuit at the wiring connector at the back of the manifold?
Would it be possible a bad fuel pump caused the code? Had p0332 on 02 avalanche and then fuel pump died I replaced it bad code went away.
+jwylde7 well if it wasn't getting proper fuel supply in theory it could cause a knock condition and set the code but I have never heard of this. Glad it went away. Thanks for dropping by the shop.
WTF?? What engine is That.?. 😧😬😵
nice video sr
+Gustavo Meza Thank you!
Yes i do know what you mean! 40 years in and out of the snapon truck every week and still waiting on my pardon.
My wife calls these videos auto repair porn.
What a boss, thanks
Mine lit up and reported the code, but a few drives after 2 bottles of gas dry and full tank of premium it went off. I never heard a ping or knock. Was I lucky or just a precursor to it coming back and having to be replaced. 92k on a 2003 5.3
azimmey well let's hope it stays off. Maybe some water got under there but dried up? You'll know what to do if it does come back. Good luck and thanks for watching!
thanks Car Doctor
If I'm getting an apparent Spark Knock and have no engine code, can it still be the Knock Sensor?
+troymassey90 Probably but more likely a fuel, ignition or EGR problem. Even an internal engine mechanical issue can cause knock that sounds like pinging.
did the sensors with wiring harness twice☹☹☹ and i still have the lite
Did you use OE parts? Correctly torque sensors and make sure not to drop them before installation?
@@ThecardoctorTV after watching that vid u suggested and yours i have doubts. i know it wasnt torqued but i made em tight as hell and the gasket for water i didnt do , bought the parts from 1a auto dont remember them saying ac delco
@@geraldturner8377 over tightening ruins the sensors. Non-OE parts are problematic.
@@ThecardoctorTV AGREED ON THE SENSORS and over tightening . thanks for the info when i saw u had ac delco my heart jumped😒 i was hoping you knew about a1 auto and bout parts there .greatly appreciated
i have a 2002 trailblazer my check engine light came on while I was driving. i hooked up my scanner and the code i got was a p0327 which is a bad knock sensor i replace the old knock sensor and my light went off. i drive and it comes back on. do you know what my problem may be?
+LeMark Wash maybe a defective knock sensor. Also want to make sure you don't have internal engine noise or timing chain issues that might cause this. Good luck.
+The Car Doctor thanks for the information
