Scotty where can I find number 5 I can't find that on amazon
Where do you recommend I buy this specific part from??
Wow...this channel has taught me a ton about my car...when i go to the mechanic they are shocked by what i kno...i cannot say thank u enough
Leela Crissy me too !! Plus my dad taught me some knowledge I be telling him what’s wrong before he check it out😂😂💕
Why you still going to the mechanic
Haha. This comment! I had a dealer call me a c*nt and all sorts of other names because I stood over the engine and pointed out all the faults with it after he told me it was fine. All thanks to Mr Kilmer 😂
@@stephaniesheridan5474 I've done over $1,000 dollars of repairs/additions to my car by myself.. Only time I'll go to a mechanic is when theres a tool that's too expensive to use.. And even then I'll go to my first job site (I used to take off bumpers and just disassemble/help out the mechanics when I wasn't sweeping and cleaning) and they'll usually let me use the equipment free of charge.. It's good to have friends in high places..
Never tell them you know what it's they hate that just do it yourself avoid the rip off 👍
Scotty you've got the best quality auto-repair content I've seen on RUclips. Most mechanics would charge you even for a simple explanation of something. You're great buddy keep up the good work!!
This guy's shtick is hilarious. The transitions, and way he speaks, all accompanied by the education makes it worth every minute.
I just changed the Variable Valve Solenoid by myself! And now its going well over 3000 RPM. Thank you so much for this very detailed video!!!
Did you have a knock?
How did you know yours was bad?
I have no clue how I am not subscribed to you already. That’s my bad. Your videos always lift my spirit when I gotta do something I’ve never done before. Thanks for being here.
this guy is so enthusiastic.. i love it
Vtec doesn't kick in without the stupid beauty cover
Same goes for Toyota
Wow, I actually had to do this exact repair on my 02 CR-V (same engine) last winter. It would chug when it got above 3k RPM. I got a P1259 code. Replaced that VTEC solenoid and it's been fine ever since.
Is that a 2002 Honda engine in this video ? I have a 08 Accord 4cyl and I'm trying to figure out what is leaking on passenger side, 275k miles
That’s an Element in the video, but it’s still the same K series engine, which your Accord has. I would definitely check your VTEC solenoid gasket; they are prone to leaking.
Scotty your the Best, a mechanic just tried to charge me $442 for this simple repair job for my daughters truck.... Thank you for what you do!! 🙌
You should rename the title "when your vtec doesn't kick in, yo!!!!"
Haha, I get it!!
Absolutely
💀
Oh yes, the VTEC solenoid assembly. Had to replace that on my 05 CR-V. From my experience usually the only time that those things go bad is either due to lack of oil changes or just simply due to age if the car has a lot of miles on it as well. Very easy to do and not horribly expensive unlike some other things on these older Hondas.
Nice video! From my personal experience with several Honda's I just replaced the gasket on the VTEC solenoid. Costs a few bucks and works perfectly.
"Well, it certainly goes over 3k RPM now!" *chirps second* lol
Thanks Scotty, this video really helped out. Oil change did the trick for the engine sputtering but i may still have to change the vvt solenoid to get the check engine light to stay off
lol Scotty chirpin the tires, well it goes over 3000 now lol
o OK thx , yea I didn't think about cleaning the intake manifold after I took the old one off, just use a brush or something to clean it
wire brush is a bit much, usually a rag and some brake clean has worked well for me
O OK thx
U own a Honda?, I see a vtech motor in as your picture
Hey also, my Camaro doesn't start unless I jump it off, auto zone told me the battery was good, could it be the altenator
13 Years as a technician and master tech for Acura, i never once saw a VTEC solenoid fail, not by me or by one of the other 24 techs that i work with,, in 13 years! .. 10 times out of 10, if it throws a VTEC code it's because the car is very Low On Oil .. Very low.. Which causes interruption of oil pressure to the solenoid and a VTEC code Will set.. , when that happens the car defaults to a "Limp home" mode which makes the computer limit engine rpm to 3000 rpm.(unless you cycle the key, then it will drive normally, unless it occurs again)) Scotty just unplugged it to set the code for this video no doubt
you are mistaken because I've seen numerous Honda Elements with that same problem including mine
allen luangrath I had to change our the vetch module just like Scotty did and my Element ran like a champ afterwards. Also and oil change, engine flush and general tune up 🤔
@@_Diggler No doubt in my mind that it will run it's a honda they go forever
It is very expensive, to replace,so another alternative is, take it off, clean it, replace the gaskets, reinstall and most times the problem is solved, as the comment by the mechanic above stated.
I have had like 3 car problems that I learned about and fixed myself on this channel. I mean... wow.
I had the same problem in my old rsx and it was the screen that was dirty in the solenoid. Replaced the screen cleaned it up nicely and she ran great no cel or bog. $12 fix!
I bet that old corvette in your outro has the original chev LT 1 for the engine.I can hear the lumpy cam that it came with.
+MrBeeradb1 yes
Vtec has been kicking oil all over my engine bay for past two years. I didn't tighten down my vtec solenoid enough after doing my first headgasket ever on my daily driver. Finally troubleshot that P2646 a actuator arm system blah blah blah yesterday and tracked it down to that. It's fixed. No more CEL, no more oily engine bay and constantly checking/filling the oil. Replaced the o2 sensor yesterday as well, that got ruined from driving around with blown headgasket two years ago. Damn those things are expensive. No more cylinder misfires either!
scotty, this exact precise video is just why you are so great. I know you have been getting unrightfully bashed for your honesty about over engineered cars. You seemed to be a little more forgiving in this video till you got to the beauty cover. Keep up the work.
I love this guy he really knows his stuff man every time he hits a dead on on every car. There aren’t too many mechanics like him anymore !
Follow him I like his video he really does deserve it . Thumbs up man great job
Thanks again scotty, fixed more issues for me and my buddies than any shop
I had the same problem with my rsx and changed the solenoid and still runs funny and got the code again
1:36 Wind effect shot!
Ah....my Element just came up with this one......thanks for the video showing the solution!
This is a great starting point. On the "element" you WILL be removing the left motor mount to remove the power steering pump and tensioner pully to clean the little screen behind the cover. the hardest part is the belt reinstall its just time consuming about an hour. The solenoid in the back of the engine is tough. remove the power steering hose and metal support bracket. I tied mine over to the driver side with a bungee strap. after you remove the 2 electrical connections there are 2 plastic wire anchors on the metal heat shield they are difficult to remove. The rest is fairly simple
You did it the hard way. You do not have to remove anything other than the oil filter for access to the VVY assembly.
I replaced the filter/O-ring on my Element and my Accord (same K24 engine) by moving the power steering pump hose bracket out of the way and holding it in place with a bungee cord. After undoing the front connections from above, I removed the oil filter (you should change the oil and filter anyway) for better access from below with the car on front ramps. It is also much easier to use the torque wrench from below.
"Stupid beauty cover" hahahahahah love it. That should be on a T-Shirt with your name on it Scotty Kilmer.
I have an '01 that does just what he is saying about poor performance - keep in mind.... when the car is cold the solenoid works fine --- you really have to have HOT oil and have to run the car for about 45 minutes at highway speeds - then slow up a bit - and then... really romp on the gas pedal to make it kick down a gear, when it tries to upshift - that is when the 3,000rpm jumps happen (Engine shutting down)... It sort of reminds you of a rev limiter kicking in... Easy fix - like he said - just hard to see. Thanks Scotty - you've helped me in the past with some things... :)
Cheers thank you for eliminating many hassles of getting the actuator and still had the same problem. 2009 Acura TSX code shown P1009 series. ManYourAmechanic.!!! Toots
I had to do one of those once. I don't remember the exact engine but it was on my Niece's Accord. One of those three bolts was in a position we couldn't get to. We ended up having to modify the socket into a wrench like doohickey. All of my wrenches were too thick, a socket could get on but there was no room for a ratchet. We cut the socket down shorter and welded it to a wrench we cut.
Thanks. I have this issue with my wife's Mitsubishi Fuzion in the Philippines. I was told it was the fuel pump, the transmission, and a few other things before I realized that this was the problem.
If it was leaking it was due to the gasket seal which only cost 24 bucks. Im a Honda mechanic in Orlando Honda and the Vtec Solenoid system don't go bad, it only has seals which you can see in the video.
Craz! Ness r u still in Orlando? Get at me
And if replacing the whole assembly doesn't work then what do you do?
OrBust add 20 50 oil
RandomGolf So we've already put in 10 30 when it calls for 5 20 and still throws the code but only on hot days. We are baffled.
Can you just buy the seals or does Honda make you buy the whole thing
You could also try cleaning it and replacing all the gaskets on the Solenoid.
That's exactly what happened to my 17 year old Lexus. Luckily I was only 2 blocks from home and limped back. CEL on so had the code. Easy repair. Screen was clean and oil+filter changed every 4K. Just bad luck. Otherwise the car has been very reliable all these years.
good vid scotty scotty, i had a similar problem on a alfa 156 1.8 twin spark [ vvti],changed the valve, oil and oil filter,problem solved.
hey scotty u know those beauty covers on fords are made of recycled denim and they actually absorb engine noise
This saved me so much time and money. Thank you!!!
Scotty I got a d16v1 i think it’s the best! I got power and cheaper parts everything’s good! I would love it if you made some more videos on maintenances on these engines And any tips like this would b great ! Big respect scotty
I think we've seen this Element show up at Scotty's garage before. Honda's K24 engine has an excellent reputation for reliability. With him mentioning dirty oil as the possible culprit, it seems like maybe the owner isn't the best about checking/changing the oil on schedule. It's that kind of crap that makes me concerned about buying a car used. Why is it so hard for some people to do basic maintenance?
Good man. I wish i lived near Houston.
toyota echo, 2005, I got it at 100,000km. now at 200,000km, all my time engine hated hills , changing auto to 3rd gear just made it rev, without must power gain, mid december 20021, I youtubed what vvti was, and set about trying to forse the engine to DO vvti, 2nd gear in the auto, up and down hills on a freeway- Melbourne to ballarat, - it worked, something changed, and no longer do i want to kick the heck out of the accelerator, , now -even on the flat open road, the engine, is powerful and certain, -lol, just when i almost talked myself into trading it in, I have always changed oil on time etc, but some extra presure must have clear the ports, and maybe cleaned out the catalytic converter, even now the start is diferent too
Well Scotty......I watch a lot of your vids.....but this vid in particular was very helpful as I have an 03 Honda Element with 188k on it with a leaky VTEC solenoid......it started w the check engine and now wont go over 3k......I remved and tested the switch and it was good......now gunna do the full Monty and replace the whole part like u did.......thanks for the info........Subscribed
I use a mirror with a handle to hold to see the bolts to screw them back in, makes the job so easy..... but i sure have experience doing it.. every single time it is time to change the oil after i change it variable solenoid goes bad, The oil is not clogged up just regular oil in color when time to change it... I have had to do this from day one of 4 years after every oil change and this part is not cheap around 104.00 ... And so far I have not figured out why it goes out each time I change the oil it usually goes out within two days of changing the oil... i use Castrol GTX High Mileage 5W-20 Engine Oil ... i know its the right grade, and that brand i would think would be great for it.
I would've replaced the seal which probably was the issue. These valves don't go bad frequently.
welp that would explain why im losing so much oil. nothing in the exhaust or coolant and im losing a quart a week. Glad i watched this. didn't know i could reach it from the top
I have a 2005 Honda Civic Ex. Throwing that code. We changed the oil, added an engine cleaner and replaced the gasket. Still threw the code. So we replaced the solenoid. Still throwing the code. The whole engine jumps when it gets to about 3500 rpm. Any suggestions on next steps?
Nothing would fix mine. Found the issue changing valve cover gasket. A plug (bolt) had fallen out and was laying up in the head. This was downstream of the VTEC Selenoid so it wouldn't build oil pressure. Loctite fixed my problem now she sails up to 6-grand no problem.
I've really learned alot from you. Thank you so much.
Your the best Scotty, thank you 😊
Hey scotty would that problem also affect the knock sensor on a honda accord (specifically 2004 accord 2.4)
i love this channel you make everything more simple I love it!!!!
Been your number one fan from day one. I have a Nissan. 2012 that blows a lot of black smoke do you have any general ideas?
Hi Scotty, 2012 CRV here with 88k miles. I have the vtec rattle on start. Thought I saw in one of your vids that the noise isn’t an issue? Car runs great otherwise
Gotta love the ole honda, 5 minute video and 5 bolts to change a major engine component. Not to mention chirping those tires
Nice sir 👍
1:35 scotty reminiscing the good ole days when he had more hair driving a convertible with the top down and his hair dancing in the wind
Straight to the point love the videos
Hey, I thought you said to always disconnect the battery when connecting / disconnecting any parts, so Not to screw up the computer or electrical system....
Thanks for ALL these great vids Scotty!
+235chuck don't need to for this part. It has no power when engine is shut off
+Scotty Kilmer OK. Less steps = QUICKER Fix! Thank You Mister Kilmer!
6th video in 2 days going to do this on mine...ur 👌
Scotty you amaze me with your knowledge . Thanks for sharing it.
Hi Scotty, Thanks for the massive time you spend teaching car repair! I have a question. I saw an app that had the ability to show, in a curve/chart format, VVT function. I have been using Torque pro an it is pretty nice. But I don't see the ability to plot the actual timing as the car is driven. I drive a Mazda 2001 It support OBD2. Do you know the app I refer to?
greeting. in Toyota work the same way, specific yaris, tks and success in your projects
tx you so much for this tutorial!!
Thank you Scotty you help me out tremendously and keep up the good job
I love how you chirped 2nd lol
Best Video on P2646 Code repair for Honda VVT ....
EASY DIY video. Thank you
Thanks!
I'm your biggest fan Scotty I always love your videos and teaches me alot... 👍🤘 Your awesome Scotty
Thanks for the support!
Is it possible that the oil pump could be weak causing low oil pressure only asking because we've done this repair and visually checked the wiring harness for damage cleaned connectors changed oil and we changed the screen under the belt tensioner also do you think you could do a video on how to check a wire with a multimeter for a short to ground and a short to power and what to do about it if you find one
When I heard you say it wouldn't go over 3000 rpm my ears perked a bit. I've got a 91 Pontiac Sunbird that hesitates at 3000 rpm, then when you give her a good amount more gas she bucks up to 5k in an instant. Hoping you have some insight as to what that might be.
How much does oil viscosity affect the VVT operation?
Gotta love that windswept look @ 1:36
I have a 2004 honda accord 2.4l and is auto, if you know that car have the ecu under the evaporator and the evap was leaking coolant so that make the ecu goes bad so i changed for another one from the junkyard, i needed to reprogram the key (immobilizer) but now the car won't pass 3 rpms i find out the car that i took the ECU had MAF sensor but my car don't mine use MAP sensor the codes actually are these ( p2185- ECT sensor 2 circuit high, p01012- MAF SENSOR "wich the car does not have" circuit low voltage, HO2S heater circuit malfunction secondary Btw already replaced the variable timing and clean those little oil filters.
Thanks, you just saved me $150 bucks
Scotty Kilmer you are a hoot.
remind me not to buy things like that ,,,,,the simpler the better i say ,,,,your the man scott
That 'filter screen' you refer to possibly getting clogged up--what are you referring to there? Is that the one you have to remove the power steering pump to get to?
400.000 subs! good job scotty
Andrew Watson
Now he has like 2.4 million in 3 years. Wow 3 years ago from mow
Dude you are so good at what you do! You been blessed!
Had a ruff running '02 Corolla with VVT, Tech showed me a cracked solenoid, and a chip of it that was not able to be retrieved with a magnet fell into a cylinder, and took 1-2 hrs to retrieve. Total repair bill, $570.00. What would make the solenoid crack ? I think he cracked it trying to remove it. BTW, he used Alldata shop manual.
+Joseph Wolchak they rarely crack by themselves, I've never seen it
+Scotty Kilmer Thank you, SK, that's what I thought. I think I got jobbed. No way it shoud crack by itself just sitting there. He did show it to me tho.
"the stupid beauty cover" LOL you're funny
Honda element baby, she's a beauty!!!!
**vtec wasn't kicking in
+faizan joyia (mac man) Or how to fix VTEC won't kick in =D
YO
faizan joyia yo
It helps to use a mirror when you have to work where you can't see
have you ever ran into a problem where the pins that lock the vtec rockers to the valves get stuck engaged?
ive yet to see one of those screens be clogged. but yeah majority of the times a oil change fixes the issue. its usually 5000 over for a oil change when this code comes on
Scotty you are the man
Hey Scotty i always bet my money on you, didn' t loose till now.
These videos are entertaining to watch in your spare time. Keep up the awesome work!
on an 05' Accord, is it possible to replace the VVT Actuator (properly) without removing the timing chain?
I bought a 2020 Accord with 56 miles on it. The VTC Valve was diagnosed at the dealer as being the culprit for problems. Symptoms included: Jerking or Bucking while driving on the hiway, Engine stalled five times while sitting in a fast food line in drive. How could that part be bad on a brand new car?
Good Info
Just perfectly done, mr. Kilmer!
You once again are the Best on RUclips! Would you recommend switching out just the switch on the unit?
People need to be careful with those VTEC engines. My buddy has one and he says when VTEC kicks in the torque is so high it can actually flip the car over! Of course this is only possible once you put on the NOS stickers.
Saw an Acura with NOS stickers and a Monster enegry drink logo on the back glass outrun a school bus one time. True story.
Scot. i bought a 2001 nissan pathfinder 4wd with a bad engine. I bought everything to get to run like new( engine rebuild kit that included everything, timing kit including the oil pump, water pump, belts some hoses, oil pressure sender switch, even the 2 thermostats. I took it to a shop to get it rebuild and they did but after a few days the engine light came on and it had p1135 variable timing solenoid bank 1, and p0138 and p0139 O2 sensor 2 bank 1 slow response and high voltage. I replace both solenoids, erased the codes and did a drive test and completed the cycle twice and same codes keep on coming each time. overheated going uphill, AC on or off, the radiator was also new. after a week or so, the light turned off on its own. So got it pass smog in california. the light came on after driving long distances. the car feels fine when its cold but when it get to normal temp starts to loss some power. since the shop i took it to is really far i need some ideas on what it can try to fix it. when cold and start the vehicle the oil light blinks for like 2 seconds and it turns off. since there is no coolant leaks or compression going to the coolant and most of the components have been changed i figured is probably something to do with the oil pressure. i was at the shop few times and saw everything been washed piece by piece so i don't think is the vain that goes from the oil pump the solenoids. everything was order to exact size. the only i can not say i seen been done is the heads. supposedly they had their own head shop. one last thing is that when at normal temp if you try to hold it to 1500 rpm starts to jump(ex: from 1400 to 1600) nut if you just step on the has normal you wouldn't feel it. many people has the same issue with this vehicle. I have seen at many different forums and they don't have a clue. the air pockets have also been released. please let me know what you think and I'm sure it will help many people. thank you ..... hope to here from you..
realize hardly anyone these days rebuilds an engine correctly. Guy just did a crap job. Personally I advise customers to junk those when the engines go out, or look for a low mileage used engine. You're chasing the dragon now, good luck, but realize it's probably just poor rebuilding work on that engine.
thats what i was thinking. im a diesel mechanic but only worked in military vehicles, Tanks, Etc.. im going to star checking the timing and go from there. thank you Scot..
Hey there Scotty! I just bought a used car, 2008 Toyota Yaris (Sedan) with a 1.3L engine (engine: 2NZ-FE) that has 36,000 miles.. I've been having idle problems when the AC is on.. The normal idle is around 650-700 rpm.. but when the AC compressor kicks in, the idle drops to around 450-500 rpm.. I already cleaned the throttle body and mass air flow sensor, I also replaced the sparkplugs but still the rpm would drop when the AC is on.
+Jonelle Loresca try a new iac valve, pray it's not the compressor going out
+Scotty Kilmer Where can I find the IAC valve? is it near the throttle body? These things are new to me.. I'm not used to working on modern cars where everything is controlled by the ECU. And by the way.. What are the symptoms of a bad compressor? The AC seems to be cooling fine in 90°F weather...
Scotty. I have a similar problem. It causes intermittent hesitation. Im suspecting its the same valve you mentioned. I have no check engine light or codes for it. But i noticed it is more frequent in hot weather. Do problems like this get enhanced with environmental temps?
Following.. Needing to know, also.
@@chancedulaney774 it was the throttle body and oil control valve. Replaced them and it solved my issue.
