2002-2006 LEXUS ES300 ES330 TOYOTA CAMRY KNOCK SENSOR REPLACED 

Thanks just changed on my 02 Es300 190,000 miles runs like a charm!l

Absolutely correct on the A/F ratio sensor being a different component than O2 sensor! Bravo

Just wanted to say this video is awesome. I had to change my coolant bypass hose. And this video is clutch af bc that’s literally the last hose you undid before your knock censors. Thank man video gives you the run down on changing half of anything I’ve replaced

Excellent detailed description and good camera angle. I really needed this level of explanation. Thank you!

Thank you so much very well made I am a graduate mechanic and you explain it very simple and to the point you should do this for a living

Dam, that looks like a nightmare, your really good mechanic bro, I’m glad I found your video , it will help me out huge

Pulling the top of the air box is a great time to examine your MAF sensor for buildup

Great video he gets to the point he shows you what to do and thats all anybody wants

Awesome video and great explanation man! Thanks for the extra add in on the o2 and fuel sensor, I'm gonna tackle my first knock sensors myself this week. Looks fun and time consuming Haha.

The BEST VIDEO. Thank you sir!!! I am going to change out the spark plugs for my son's 2004 ES330 this weekend (He also help me). Your video is so helpful to us. Thanks again🙏

I would also add to consider replacing the radiator hoses while you’re way deep in there... thank you for sharing, I have a Highlander with 298000 mls thats gonna need the sensors replaced....you shown me the way 👏👏👏😎🌺🌈🤙🏽

I want to thank Chris again I helped my buddy do this and probably saved him 1 thousand dollars. I would highly recommend however that you find the proper torque specs for the manifold bolts.Drain some of the coolant so you do not get any into the cylinders . Use a vacuum cleaner to clean up all the dirt to keep it out of the cylinders. and finally yes change both sensors( they are identical and have the same life expectancy) and the wiring harness and the air/fuel sensor because you don't want to do this again . The older the car is the more fragile /brittle the wiring harnesses /hoses/ plastic pcs. become and you should pay close attention to these as you put everything back together because just disturbing them can be enough to cause them to fail and you do want the car to start after all this.

Great video! Might I suggest to drain the entire coolant system beforehand? The last thing you need is to get antifreeze into the intake. Doesn't take that much time and it'll save you a buncha headache if you accidentally dump some coolant into those ports.

A GREAT BIG THANKS. Now I know what my mechanic didn't do.

CRIS THANKS FOR SHARING YOUR KNOWLEDGE.

Just wanted to say thanks! Saved me a ton of money 🤙

Thank you for this video. I have to do this, but not looking forward to it haha. Thanks again.

This helped me so much. Thank you!!

Chris I like your take on the bank one sensor you got with the plenum off. I did it from under the car and it was the hardest/tightened thing I have every done to a car!!

great vid, you should create more. very helpful

Thank Chris, good video and info.

Detailed and precise information

good job . keep it up... makes peoples life easy when you post the video like this. and those stealership wont get any more business.....

Chris thanks a million! So I am currently changing my knock sensor on my 2006 Sienna is the motor in the video similar? The same? There are other sensors @15:03 at the bases of the heads what do those do and how are they removed I broke one.... Thanks

Excellent demonstration and camera work!

Your nails are longer than some females I know…great video!!!

Hi Chris. I followed your instructions, and put everything back together. Upon startup, there is a fuel odor from under the hood. If I let it run a minute, white smoke starts to come up from under the throttle body. Any ideas why this would occur? I just turned it off because I didn't want to start an engine fire. Thanks.

thanks for the video bro about to handle own for my aunt. I wouldn't be doing it if not for this video thanks.

very nice video. many thanks Chris

i was gonna buy a 02 camry with bad knock sensors but after this very helpful video i dont think so , its too much work.but thank you for the video

Thank you, Chris!

Nice helpful vid. Good steady camera work too. I hear many people don't even bother putting that one back plenum bolt on. Then if they have to take it off again later, that's one step they don't need.

OMG! No wonder my mechanic hasn't called me back yet. Told him code is reading knock sensor. smh. Thanks for the video.

Thanks amazing job.

Good video good quality good explanation 💪🏽💪🏽💪🏽

Very Informative Video Thank You

You should always remove the negative battery terminal first before the positive one or just the negative one if you are not taking the battery out. If you try removing the positive one first and the wrench hits ground anywhere you will short the battery out. But if you remove the negative one first and the wrench hits ground anywhere nothing will happen. The same thing applies when reconnecting the terminals - positive one goes on first before the negative one.

Awesome video! You saved me so much money!

thank you i bought one have to change them but i also noticed that the sensor for the temp on driver side the connector is missing someone broke it no were to be found

Thanks for the video. I have a lexus es300. At 2:55 I noticed you removed a sensor form the vacuum solinoid. I am not seeing such a sensor in my es300. The socket is there for it. What does this mean for my car. Thanks

Wow, very fast, very instructional. Thx A Lot!! I have the previous ES300 model with a knock sensor code on right now. And boy do these have similar if not the same engine. I'm surprised how some ppl have this issue already tho. I thought it was a worn out issue. I have 230,000miles on mine and first time i EVER seen my check engine light turn on in 4years of owning this car!! Lol.. But, anyways very Good video thank you.

Hey Chris, awesome awesome awesome,video.

Hi Chris, My Engine light is ON, my mechanic told me that knock sensors need to be changed, I am thinking about change my Knock sensors in my 06 IS 350, any advice for me ? btw mine is over 272K miles

Chris like your education video on how to change the knock sensor... the only thing I would warn anyone of doing this is to use the 9/16 bolt removal on the plenum as the test point... meaning if you CANNOT get this "Tough One OFF" then stop and go no further...!!! I know you are not endorsing any manufactures but Would you tell what or where you can get the "angle ratchet wrench" you use to even get to this fastener off? I've tried almost everything I could find at Lowes, Home Depot, and Harbor Freight in trying to get to this fastener...

Nice job Chris!! 👍

Clean car dude

Oh yes, replace both sensors plus wire harness

Omg All this tear down

Transverse v6 engines are terrible to work on with tasks that should be simple like changing spark plugs on the rear cylinder bank. Good video.

great video man

I did the A/F sensor in 15 minutes going under the car using only ramps for front wheels. Easy . You have to go behind the engine . With the 1/2 inch Pry bar extention . Some people remove the driver side rim and tire off the car and the small splash guard behind that wheel and go in trough the side .use a Half inch Rachet attached to a long prybar extention . With the Ssensor socket. . There is a sensor socket for the 3/8 rachet . Dont get that one . Get the one for the 1/2 inch . For more strengh as you will have to pry it loose. I edit to say this : ON ALL THESE SENSORS , MAKE SURE YOU USED THE BRAND DENSO . USE DENSO ONLY . AS THESE LEXUS DONT LIKE OTHER BRANDS. AND WILL MALFUNCTION AGAIN. USE DENSO ONLY . When doing knock sensors Make sure your replace the 3 spark plugs in the rear of engine and coil boots . Do it so that you dont have to take it apart again when a spark plug goes out or something . Do it now while its all taken appart. Do your PCV valve Aswell . You dont want to keep taking this engine apart all the time its alot of work . Replace EVERYTHING you can on this one single Job . Always Remember to Tape off them holes man . To.prevent anything going in .! Holly cow man .cover those holes. If you drop a screw in the hole man you got problems. Used long tape and tape them all shut. Click link to see all this done THE RIGHT WAY ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fybPb_d1vrU.html

Great video!

Do rinse the driveway or road down with some water; get that coolant out of there. Otherwise an animal will lick it up and die from it. Happens all the time. Anyway, thanks for a great video. I'll be ready if this ever happens to me. I've removed the plenum to do the valve cover gaskets (damn that wire harness!) but haven't had to pull the lower manifold yet. Good call on that back left plenum bolt too. I have a cheapo flex-head 3/8" wrench that I can barely squeeze back there with a socket on it and fit on that bolt head (and I do mean BARELY!!)

good video, changing both my sensors and wire harness in the next day or two. I'm sure this will be my go to video should I need.

How long did that counterfeit denso knock sensor last?

What was the reason you had to change the Knock Sensors? What was the problem and symptoms? Knocking with regular gas?

Thank you. Especially for the detailed info on locations and what type of tool to use. Those are a lot of steps. I kept waiting for you to get to the part and you did this before? I'm amazed. Did you get this done in the time that it took to record this video? The Toyota dealership says I should replace all of these parts-both Knock Sensors, Knock Sensor Wire Harness, Intake Gasket, Intake Platinum Gasket, Valve Cover Gasket, PCV Valve and the Thermostat and ORing. In your opinion, is it worth replacing all of these parts for a 1999 ES300? When you say we won't be able to remove the plenum, if this is the case, then what should we do to get to the Knock Sensors? Can we get to the Knock Sensors w/o taking the plenum completely off, like to move it to the side like you did other parts?

Should i buy a new intake manifold gasket?

I’m about to open mine up and this video is my class good job awesome detail, I didn’t realize how much shit had to come off just to swap out valve cover gaskets damn. Out of curiosity how much does a job like this cost? Just to give me more motivation to do it myself. Thanks

Imagine having to be one of the mechanics who's there when they test the cars out? lol and some guy keeps changing settings or they try different parts so you gotta go through all this several times a day? I always wondered how much of that goes on when these manufacturers run all their tests. It's a pretty funny image

First of all, thank you for posting a very instructive video. I have a question. At 11:31, the part you removed (called plantum?) has a white part and black part. Can you separate those two parts to simply the whole process a bit? I have a 2001 lexus with error code p0330 (bank 2 knock sensor ). I got a quote for $500 for replacing it. I am seriously thinking about doing it myself.

Are there two knock sensors on a 2002 Camry 2.4 Liter? I thought there was only one.

I just replaced my knock sensors on my V6 camry, it was not that hard just lot of photos and labelling. There is a few points that i was to share which i found critical and useful. I hope it will help the next person that might replace the knock sensor on this type of engine. Make sure you drain all of the coolant, that is coolant in the radiator, front and rear engine block ( yes! There are drain two drain plugs one at the front of the engine and one at the rear). If you dont drain all of the coolant it might leak into your cylinder when you lift in the cylinder block (shown in the video) Unless you have bought a new coolant bypass hose, there is no need to take that out off to access the knock sensor. I replaced mine without taking the hose off. Make sure you torque them to the right spec! Also there is no need to remove the fuel injectors, it can be left on to the cylinder block p and move aside (one less thing to unbolt)

Great video. Are both knock sensors the same part number?

You should honored by medal for patient..)))

Thanks for the video Chris, . great help Two questions did you replace the manifold gasket,if so how much was it.

Great video and explanation but I was getting anxiety watching you work over an open intake! I like to put tape over it to prevent anything like nuts and bolts falling down into it

I gotta do a 2002 lexus es thanks bro .

Thanks, how many wire harness needed for both knock sensors? One or two?

Hi, i have a question for you. Why did you remove the injector rail? Can it be left on with the cylinder block and remove as one piece?

Did you reuse your hex intake bolt for the plenum an the intake itself. an if so what are thw torque specs. Thanks

Anybody know the name of the rail at 6:10 with the orange and blue sensor?

24:42 Two knock sensors located.

Great video. How you know your knock sensor was bad? Like the engine light was on or wierd sound or the car feel wierd?

Chris, about how long did it take you to complete this task? Did it take about 30 minutes, the approx. length of your video? It seems like you're undoing a puzzle then putting it back together.

Hey. I wanted to clarify how to find out the performance of the knock sensor?

would the process be the same on my 1998 lexus es 300? Are they the same engine?

Did your engine make a knocking sound along with your other symptoms? I'm trying to diagnose a problem with mine right now

You heard of people splicing them to the one good knock sensor? I really don’t want to do this job lol but I got a p0330 in an 02 solara

Chris S I have an 04 ES 330 my reservoir underneath the battery is empty what is this reservoir used for?

Link to recommended knock sensors ?

Chris, It sure helped a lot to get an idea of kind of job you're facing & prepare yourself. . I still find of kind of "SICK" to place the sensors where they have...do you have to replace both knock sensors even if one tests fine? my part store charges $140.- ea for 97 avalon. Thanks a lot again!

Great video but may I add on? I have an 04 Solara 3.3 and the knock sensor locations are the same as 03 and prior, but the sensors are made entirely different. The 03 and before Solara models have the same sensors as shown in the video, but 04-08 V6 Solaras use the ring type sensors that are mounted with bolts. I had to look it up by the year on RockAuto before making an order and surely enough, 03 and 04 have different sensors lol.

Do u have the part number for the air fuel sensor bank 1 sensor 1?

Holy crap thats a lot of dismantling, definitely mark everything with different colour paint markers so you know where everything goes back.

I need a great mechanic to work on my 2003 lexus es300 in the Phx Az area.

hey what a gmail or # we can for advise I got code po 128 po 156 snd po 330 on a Lexus 03 es 300

I have a 2002 camry v6. Replaced both knock sensors and harness. Was getting sensor #2 code then after the replacement of both I got a code on #1 knock sensor...? I went back in to check out connections and found that the harness wasnt clicked all the way and corrected it. I took it out and it shifted into overdrive for a couple test runs then I coded out again for sensor #1. Again not shifting into overdrive... any thoughts?

Remove cowl and wipers to get to the plenum bolts, plus get more room to work.

(Screw goes flying from engine cover..) Doh!!!

Hell, I'd change both knock sensors, the harness, and the 3 rear spark plugs while everything's apart.

great video..you should post more DIY videos

The hardest part - the back three nuts hodling the bracket - you did not show.. 1 14mm and 2 12 mm nuts. what the flex wrench you used and how you do it

This must be a Lexus. My 2002 Camry has different size nuts and different styles than described here.

Are you located anywhere near Phx. Az?

You massaged the throttle body and voom the intake manifold disappears, pretty easy stuff

How many knock sensor I need ?

Good video bro, I’m going to relocate the KS instead. Takes about a hour max.

14mm and 8mm vs. 9/16 and 5/16 😉

26:44 .that is a 27mm socket fit
