2002-2006 LEXUS ES300 ES330 TOYOTA CAMRY KNOCK SENSOR REPLACED

PLEASE LIKE THIS VIDEO! THANK YOU IN ADVANCE.
THIS VIDEO IS PURELY FOR EDUCATIONAL PURPOSES ONLY. I MADE THIS VIDEO TO SAVE YOU MONEY AND TO PROTECT YOU FROM THE STEALERSHIP AND THEIR OUTRAGEOUS REPAIR COSTS. IN THIS VIDEO I WILL SHOW YOU HOW TO CHANGE THE KNOCK SENSOR WIRE HARNESS AND THE, "DREADED KNOCK SENSORS." I WILL ALSO GO OVER HOW TO CHANGE THE VERY HARD TO GET TO AIR FUEL RATIO SENSOR BANK 2 SENSOR 2. THIS VIDEO IS VERY HELPFUL WITH MANY OTHER REPAIRS AS WELL, SUCH AS CHANGING YOUR SPARK PLUGS AND COILS, AIR FILTER, MASS AIR FLOW SENSOR (MAF), AND A FEW OTHER THINGS. I AM IN NO WAY A MASTER MECHANIC, BUT I REFUSE TO PAY BOGUS MECHANICS CRAZY AMOUNTS OF MONEY FOR JOBS THAT ANY SMART, MECHANICALLY INCLINED PERSON CAN DO. THIS PARTICULAR JOB WOULD HAVE COST ME $350 FOR EACH KNOCK SENSOR, $95 FOR THE WIRE HARNESS, AND 5 HOURS OF LABOR @ $135 PER HOUR ACCORDING TO THE STEALERSHIP. YOU DO THE MATH!
PLEASE LIKE THIS VIDEO! THANK YOU IN ADVANCE.

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

[@firenguyen517]

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🙏

[@8216.]

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

[@ronsteelable9405]

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.

[@dragosutalo579]

and cover the holes on the intake.

[@joevignolor4u949]

@@dragosutalo579 Good idea. When I was a young mechanic I dropped a bolt down the distributor hole on a V-8 engine and had to pull the oil pan to get it out. Since then I always plug every upward facing opening with a piece of cloth or paper towel. In all the time since then I've never had a repeat experience where I've accidentally dropped something down inside of an engine.

[@dragosutalo579]

@@joevignolor4u949 Yeah, I call it hole in one. Murphy's Law never fails. That's why is a Law and not a theory.

[@Skidmark0606]

I just made this mistake. A bit of coolant went in but the valves are fully closed. So nothing went inside. I padded it dry as best I could but there’s ever so slightly coolant in there. Am I still screwed?

[@Fun4me75]

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 👏👏👏😎🌺🌈🤙🏽

[@danswitzer2733]

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.

[@crucial414]

Thank you for watching and you are very correct about cleaning the area with a vacuum and replacing all of the components.

[@gw8827]

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

[@mst93ho]

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!!

[@crucial414]

mst93ho Thanks!

[@4seeableTV]

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.

[@squirrel36274]

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.

[@crucial414]

No problem, glad I could help.

[@squirrel36274]

Chris S , sorry i have a question i forgot to ask. Like i said i have the code for the knock sensor p0330, which is bank 2 i believe it was... But i keep seeing everyone is saying to go ahead and replace the other sensor too. Should i? And if so, do you know if they are the same part number by any chance? Sorry.

[@crucial414]

On my car, the knock sensors are the same part numbers for banks 1 and 2. The reason everyone says to change them both is just so you don't have to open the top of the motor again. It is not mandatory if there is nothing wrong with it. These knock sensors usually last a long time and do not become faulty quickly and most even last the life of the car according to the research I've done. If you can find an OEM knock sensor for cheap and you have the money, then I would change them both, but if not, then just ride it out and hope the other one does not go bad. Whatever you do, do not put the cheap, off brand knock sensors on this car. I can almost guarantee that you will end up changing it again very soon after replacing it, if it even works at all. I would definitely recommend changing the harness though!

[@squirrel36274]

[@HongNguyen-my5oq]

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)

[@4seeableTV]

If one is replacing both sensors and wire harness, you can still do it without removing the bypass hose?

[@HongNguyen-my5oq]

Of course and I did mentioned it in my post. Remember to drain all your coolants, including the engine block too.

[@hogfish09]

great vid, you should create more. very helpful

[@sandramartinez9837]

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

[@crucial414]

😁 it be like that some times

[@joevignolor4u949]

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.

[@joevignolor4u949]

@@journeycabral5710 Car batteries are only 12 volts so you can't get an electric shock from one even if you touch both the negative and positive terminals at the same time. The primary hazard with a car battery is that it can deliver a lot of current if you short it out. That's why you have to be very careful with metal tools around car batteries. If you accidentally get a wrench across a car battery it will create a huge spark and the wrench could start to get very hot and if it stays like that too long the battery could possibly explode. That's why you always take the negative terminal off first so if the positive terminal or anything connected to it touches the body of the car nothing will happen.

[@NeauxGeaux]

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...

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!!)

[@Vanessa-hn9lw]

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?

[@crucial414]

Vanessa Sampson Thank you for taking the time to watch my video. I'm glad it was helpful for you. When you go to a dealership the mechanics are trained to fix everything by their book. When you follow the dealership procedures, it sometimes makes you perform steps that you may not always have to do when you are doing a repair on your own. The parts at dealerships are usually super expensive and the mechanics hourly rates are through the roof. This video is only meant to be used as a guide, but if you watch the whole thing and do what I did... it should work out well for you. :)

[@crucial414]

Vanessa Sampson When performing any type of repair like this you must always be mindful of things that look broken or worn out. If you see something that looks suspicious, test it and/or replace it.

[@baronsnyder8971]

[@jaisenjaisen2303]

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

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.

[@waynerlee]

[@crucial414]

Wayne Lee Thanks.

[@HellShredder713]

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.

[@petersun21]

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.

[@crucial414]

You can separate the two parts, but it will not make the job easier. that part will just be in your way later.

[@danswitzer2733]

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

[@crucial414]

Thanks. I did not replace the gasket. It was still in great shape and did not need replacing.

[@dobisayek]

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!

[@binrar]

+Sid G. amazon.com sells sensors (brand new) for as cheap as $40. I don't know how much your particular sensor is, but it worth taking a look.

[@crucial414]

You definitely do not have to replace the other sensor if only one is bad. It would just suck to have to do the work a second time if the other one goes bad soon after finishing the job. I still would not do both unless I found a cheap price on a second sensor. My main concern would be more on the wire harness because some times the sensor is not bad at all even though the code reader says it is. When the wire harness is bad, it can cause your engine light to come on and falsely accuse the sensor of being bad. There are other videos on youtube that show you how to test a knock sensor with a multimeter and if you are lucky, you may find out that your knock sensor is good and does not even need replacing and the harness is actually the culprit. No matter what, I would change the harness because it is not that expensive.

[@dobisayek]

+Chris S (CRUCIAL414) You're right again..., i see/hear a lot that main culprit is indeed the wire harness. But yet to find a reliable way to test the sensor, beside continuity test which isn't 100%.But it'd be safe, at 15oKmls. to replace sensors as well. "fuel/air mixture sensor(?),is said to be replaced too.

[@zenitramable]

you still have to go thru the whole process to replace the harness correct?

[@danblanzara3174]

Should i buy a new intake manifold gasket?

[@Tekatogokuta]

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

[@Vanessa-hn9lw]

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.

[@crucial414]

It took about an hour to an hour and a half the first time. After doing it a few times now I can do the entire thing in about 40-45 minutes with the correct tools. This video is shortened to make it easier to watch and understand.

[@jw_nomad]

@Chris S You are such a patient and nice , skillful car surgeon!

[@HongNguyen-my5oq]

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?

[@crucial414]

[@camilo11315]

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

[@crucial414]

camilo11315 The engine light eventually came on a few days after the car was running weird. The car had barely any acceleration and my gas mileage was low as well. The knock sensor controls the timing of the engine so when it went bad, I believe it went into what is called, "limp home mode." This prevents you from damaging your engine.

[@MEDCANWhitewidow]

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