2012 - 2020 GM Ecotec 1.4L Turbo Engine Ticking Noise EVAP Canister Purge Solenoid Valve Replacement
ฝัง
- เผยแพร่เมื่อ 9 ก.ค. 2024
- In this video we show how to identify ONE possible source of annoying ticking noises from the GM Ecotec 1.4L turbocharged engine, which is due to a dying EVAP canister purge solenoid valve assembly. This engine is found in the Chevrolet Cruze and Chevrolet Sonic, among other GM models. Once identified, we go over how to replace this particular part with the latest genuine GM version of the part. The solenoid starts this louder abnormal ticking sound as it approaches end of life (they are never whisper quiet as there is some light sound that is normal though). If you let it go to long, eventually you will get a diagnostic trouble code (DTC) of P0496 when it fails altogether. Now some ticking sound on these GM 1.4L engines is normal too, and from the fuel injector design. So pay careful attention to the sound in the video during the unplug/plug wiring harness test, which is distinct from the "normal" ticking of a GM Ecotec 1.4L engine.
The vehicle shown is a 2012 Chevrolet Cruze ECO, but the procedure is applicable to any Chevrolet or Buick from 2012 thru 2020 with the Ecotec 1.4L turbocharged engine including the following models:
Chevrolet Sonic, Chevrolet Cruze, Chevrolet Trax, and Buick Encore
Chevrolet Sonic replace EVAP Purge Solenoid ticking noise
Chevrolet Cruze replace EVAP Purge Solenoid ticking noise
Chevrolet Trax replace EVAP Purge Solenoid ticking noise
Buick Encore replace EVAP Purge Solenoid ticking noise

Awesome video man! And thank you for all the helpful replys below. True competence is often best displayed by effective communication. You sure nailed that one.
Thank you so much. This was exactly what my daughters car was doing and it was driving me nuts. Thanks for the help and avoiding the mechanic.
Thank you for this video! i thought my ticking noise was going to be a much bigger problem. thank you again
Thank you so much for this video, this is the exact problem i have on my 98 volvo v70r!
Just some advice folks, don't just load up the parts cannon on this type of issue. You have to do diag, and perform the wiring harness test I go over in the video. The GM Ecotec 1.4L has a *normal* ticking sound simply due to its fuel injector design. What you're looking for is an _additional_ abnormal sound, in this videos case, specifically from a failing purge solenoid assembly. If you do not get the results shown in the video, your sound source is elsewhere.
These solenoids are not whisper quiet to begin with, but they are also not supposed to be audible from a distance while the engine is idling either. That's what this repair vid is about addressing.
I did the test like you and the noise stopped so I put a new part in and it makes the same noise. It is loud and like I said stopped when I disconnected the power. So why would it still make this noise?
Tough to say, as you can read thru the comments for the vast majority of us this is what to do to repair this noise issue. If you can hear the noise inside the car with the doors closed and the windows up, only then is this a problem. It's _normal_ for this GM engine to make a ticking noise you can hear with the hood up. What you're listening for is not no noise, but _less_ noise. I can suggest two considerations if you still have the _hear it inside the car_ problem:
Did you use a genuine GM ACDelco part? Aftermarket ones are typically of inferior quality and construction.
Is there a check engine light, or a stored history diagnostic trouble code (DTC) in the computers memory? The noise may be related to another component in the same EVAP system.
Much love and respect from Sudan, thanks a lot
Thanks Doc.i have the same issue and went ahead and unplugged it and it made no change.it does get alot quieter when warmed up.just got this 2015 cruze with the 1.4 turbo.i remember my 2014 silverado was also noisy as heck and i listened 2 a few new trucks and had the same noise.they said it was the high pressure fuel system as well.awesome video!
Thank you so much it's been driving me nuts
Just wanted to Thank you for your Awesome advice I had the same problem with a louder knocking and it worked. Change the part and wow so quiet. 10 in
Thanks it was super easy to fix
Just saved me about $250.00 at the local garage! Thanks.
Thank you yet again i didnt know for sure that it needed to be replaced but you confirmed that it does and itd easy enough
Thanks I will change that soon. This vid helped out it does stop ticking when I unplug the sensor. I just changing the thermostat housing kit aswell.
Thanks a lot fixed the issue !
You know what? The best part about this video is you using the light and mirror to show the clip and giving more information on how to do it. That part is so far back in the engine bay that I was pretty much guessing what to do to get it disconnected. In fact the first two times I tried I couldn’t get it off at all.
It is exactly what is happening in my car, i will fix it. Thank you mate!!
One symptom of a failed purge solenoid, from my own experience, is hard starting immediately after refueling
No. That is the effect of over pressurization. That is not the cause. You have a bad timing chain tensioner. The timeing is off just so slightly that it causes back pressure. It will just break again until you tear apart the front of the engine and replace the time chain tensioner. 1:37
@@robertolson7304 hi im having this problem with my ford fiesta 2012 it stalls when you push the gas after a stop. And it also has a very very bad starting after every full up
@@robertolson7304 what he described is absolutely a symptom of a fault purge solenoid. What you’re suggesting is analogous to getting brain surgery for a headache. Start simple
Thank you. My thinking is that this is what TH-cam was created to do. Helpful money saving advice. Mind you on my 2018 they seem to have changed the damn clip so it's different now.
Thank u i have 2015 chevy cruze everytime i ask the mechanic he say that is normal i knew it wasnt normal
I have a 2018 Buick Encore. I honestly thought it's supposed to sound like that. Guess I'll change mine out then. Glad I happened upon this video.
Just remember these solenoids are not _quiet_ at all. As I mentioned in the video, the sound is a problem only when it gets loud enough to hear in the cabin or over the engine noise with the hood closed.
@@DrShock yeah it's pretty loud. It's clearly heard.
Thank you 😊
Same with my trax.. when the part arrives I will replace it soon..
I'm working on a 2002 Buick LeSabre 3.8L and the problem I'm having is with the purge solenoid. My long term fuel trim is pegged out at -25% and my short term is around -5%. The solenoid is ticking meaning it's being energized. When I disconnect it the long term fuel trim goes back to 0. With the connector unplugged I connected a test light to battery power and the other end to the negative terminal. My test light pulsates continuously. The ground is controlled by the ECU. Does that mean the ECU has a bad driver or can a faulty fuel pressure sensor cause the computer to continuously run the Evap integrity test? I haven't checked the fuel pressure sensor voltage yet but I will once I jack up the car. Please Help!
Had the EXACT same problem with my Opel Adam S they use the same engines, 1.4T, replaced it under warranty back then. Now after 3 years it came back.
The noise also comes after the car is idle a little and got warm already, it wont make any noise when cold
I replaced mine but as soon as a couple minutes with the car on it starts making a loud ticking noise.. before replacing i did have purge valve code and after fueling with gas the car would hesitate before installing a new purge valve
I replaced mine twice still makes that noise and dtc codes p0443 comes up. I measured the voltage and it fluctuates from 12v to 7v or 3v and so on. What does this mean? Thanks
Thank you very much !
I'm having this issue on my Opel Corsa 1.4 Turbo and it has 65 000 km on it.
I was wondering what that ticking noise was. I own a 2014 Trax.
I repeated everything as you did but the sound remained the same
What happens at such a time?
I just bought a 2016 chevy sonic and it has this noise thanks
I noticed a loud ticking noise coming and going while engine in park in the top manifold area..
Would the ticking happen with acceleration as well cause I have a 2015 Chevy cruz that when idling and accelerating I hear a ticking noise.
Yes
Thanks god! So anoying sound... it's driving me crazy. In the morning sounds louder...
I understand that the purge valve is responsible for the ticking, but I am wondering what moving parts are inside the purge valve that are actually moving back and forth, causing the ticking....
That would be an electricial solenoid, it moves a plunger back and forth to open or close the pathway of the fuel vapors inside the tubing
I replaced mine and it still ticks lol any other ideas??
I had an EVAP code and I replaced my evap solenoid. The brand new one that I just put on is making a ticking I've never heard before. Is there something wrong with the part?
Sounds like a non-GM aftermarket part? If so some cheaper aftermarket brands are just noisy if you read thru earlier comments here. That's not typically indicative of a problem per say.
I replaced mine with aftermarket light went off but still have ticking sound I do smell gas sometimes
Hello sir mine does the same thing my car is throwing a p0171 you think it's because of this purge valve and can I replace all the pcv plastic hoses with rubber goses
That code is unlikely to be related to the purge solenoid, it's more likely coming from the intake manifold pcv bypass valve or a vacuum line in that component area. More diagnosis would be required to confirm, too many possibilities for a comment forum diag. You could check for th pcv bypass with this check though - th-cam.com/users/shortsqGBt5skZWLI
Can this cause a startup problem due to excessive negative tank pressure ? I'm definetly getting the noise and the vehicle acted like it was starving for gas at startup(it would run for a few seconds and then die). Thanks for the video.
Usually what happens here is, if you ignore the noise and do not replace it proactively, the solenoid eventually fails enough where you get a check engine lamp on the dash lit with a code you can pull with a scan tool. This part completely failing can cause the start symptoms you describe, but you may have multiple failures going on. I'd start with pulling the codes with a scan tool (not all of them will trigger the check engine lamp), and work that list first.
I have the same issue
That's what mine did wouldn't start when I got gas
@@DrShock could it cause a Lean bank code when it starts going bad?
so i have a new 2023 kona nline and had to get this replaced the other day, problem was gone for 1 day and back to the same issue. is it possoble for a new purge valve to fail that quick? im going to bring it back in anyways just annoying listening to that noise. they told me its only affecting my gas consumption
Aftermarket parts tend to have this problem the most, vs using a genuine GM ACDelco part. In the beginning, it's just cosmetic - an annoying noise. But in the long run, the noisy part will fail and trigger a check engine light on the dash.
Can this cause a P2090 code to pop up? I am having the same sound not constantly but sometimes and I cannot find the reason for the P2090 code. So I’m wondering if these are connected. Please help if you know I don’t know anything about cars but I’ve had many repairs done trying to fix this code.
The typical code for this problem, when you let it go until the part finally fails outright, is P0496. I'm not familiar with it causing other codes, but it may be possible.
u save me 60 pound thank you very much but i wonder if u can help me with the name.of the clip is it ornage or red one but mine is green. do u know what is called plz?
I just got that noise and code p0171 could that be the problem and have to change that part ?? Help here
There are at least eight different possible causes for that code on the ecotec 1.4L, but the evap solenoid is not one of them. More likely a vacuum hose leak, or an obstruction/leak in the crankcase ventilation flow.
Would the sound change at idle ? I got a 2011 nissan versa I think bad lifters but now that I see this . I broke the stem to the purge solenoid so I jb welded it back in place . I wonder if it's that and not the lifters .
The overall sound would yes. But different engines can have different sounds for both normal and abnormal, especially across manufacturers. So I wouldn't compare a GM engine to a Nissan engine alone, for this sort of problem.
The GM Ecotec 1.4L, for example, has a perfectly normal ticking to it. That's kinda unusual to begin with engine sounds wise. It's only when you have this added noise with the purge solenoid failing that we cover in this vid, that you get an additional clue about something truly amiss. Most folks would never notice it, until the check engine light came on further down the calendar.
@@DrShock But say it does make that sound and that is the issue when you Rev the engine will the sound get louder
@@josephg8818 In my experience, these kinda tick away at a specific rate. Best test is the unplug/plug at idle like I showed. If they are failing, they fail at idle so that test gets rid of alot of other engine noise from higher rpms that could make it harder to hear it.
Mine was extremely loud, replaced it with a new AC Delco as shown, this one is evan louder. Could there be a vacuum leak? I don't detect one. Maybe the new one is defective?
Are you sure the sound is coming from the EVAP purge solenoid - there is a test early in the video to determine.
@@DrShock yes, I pulled the purge valve off and all ticking stopped. Happy to report that after driving a few days now, no more loud ticking, glad I changed it. Thank you for your helpful info.
My Chevy Trax has been ticking since brand new even after the new purge valve got put on
The Ecotec 1.4L turbo is a ticker by nature, but when you have one of these purge solenoids go you will *definitely* notice it as louder than the baseline ticking. ;-)
Same noise coming from my 2013 Cruze ltz. Just changed the purge valve and still getting the same sound. Still have no idea why
Same I just replaced the part with a brand new part and still have the clicking. So I am ordering the delco brand and retrying.
This particular GM engine has a _normal_ ticking to it. When the purge solenoid ages it adds to the melody. The unplug/plug test I showed in the video is how you determine if you have an _abnormal_ ticking noise issue relating to the purge solenoid.
The solenoid obviously makes _some_ sound when it's functioning, but as it ages the sound becomes much louder, pending a failure. If during the unplug test you are still hearing what you're commenting on, it's not related to the purge solenoid. It could be _normal_ or something else, like an exhaust manifold leak (that also makes a _ticca ticca ticca_ sound. Or an internal engine component from low oil, wear etc. Many things.
Check the hose that connects from the canister valve to the intake manifold. Also called the purge line. Sometimes there will be a ball check piece inside the hose itself that could be making the noise. If so, replace the hose, you should be able to feel it as well.
Here is how I stopped mine from ticking: I originally bought an off-brand purge valve and I put it on. It caused ticking still and the check engine light even went on. I researched around and I was reading an Amazon review on the AC Delco brand part. Someone had the same issue. All they said was they returned the off-brand part and bought the AC Delco Brand Part and it stopped the ticking. I installed the AC Delco Part just yesterday and my ticking noise is gone for now.
I was looking for a comment like this all over so hopefully someone can find this information instead of searching all over.
@@FireDredFTW Thanks
Like i ordered a EVAP Canister Purge Solenoid but there is a round thingie to the right. I just found the purge valve without any hoses if you know what i mean. So if the purge valve is broken is the round thing also broken or what does that do?
Not quite sure what you're referring to, would you be talking about the part that has the red colored retainer for the electrical connector attached to the EVAP solenoid? Or further back?
If you go to 2:37 and look right to your fingers. Theres the thing around the hoses.
Between the solenoid and the adapter
So with the EVAP solenoid assembly removed a 3:31, the connector at the intake manifold that the assembly snaps onto is in the right hand view. That connection is part of the plastic engine intake manifold. Everything removed is all one unit, if using genuine GM parts. If yours has something missing or different about that assembly itself, it could be an aftermarket design or damaged in some way.
I have the same problem so u think is from that? Did u it show Engin light on ? My remote starter won’t let me start too ? Can u plzz help me ?
And what the cause when your car shakes when you slow down? I have the same car with yours
This is just a noise problem, there is no check engine light. Though it can trigger one if you let the problem go long enough for the part to fail. If you have a check engine light, you may have other issues and should get those codes diagnosed separately.
Did I miss something? Did you show us the sound after you fixed it? That would have been helpful to compare.
For this particular model GM engine, the device has no discernible sound to show when functioning correctly. So, for all practical purposes, same sound as unplugging a defective one.
@@DrShock Thank you for reply. I installed a new one yesterday, but it still makes the loud clicking sound from the unit. Is there something you might suggest or think I can also check into that may be causing it to do that. Thanks.
1:11 you can hear the sound of the faulty part (kinda clicky or rattly)
1:14 part is unplugged and you can hear a clean idle without rattle. This is also how a new non-faulty part should be, silent as far as we can tell
@@carldrew Do the unplug/replug test. If there's no change in sound, the ticking is coming from elsewhere under the hood. If there is only ticking when the solenoid is plugged in then it's either the wrong unit for the vehicle, or a dud part.
Try checking spark plugs
My car never made this noise, and I replaced the evap purge valve, and it started ticking. I'm just gonna live with it for now that I know it's not the timing chain making that noise.
hi mate thank you very much u give me confident to do it myself. i did it today but i accidentally broke the orange or pink clip that u was find it hard to take at the begining. do u know what is the name plz?
Post a time index from the vid to be sure, but I _think_ what you are referring to is just a safety lock on the electrical harness connector. It's a small piece of plastic that helps make sure that the electrical connector does not accidentally get depressed and come loose. If so, its not a big deal. You could procure one at some point from a wreck at a you pull your own parts type salvage yard. Like an LKQ PYP site.
If instead you mean the retainer for the vacuum line that connects into the solenoid, well if that broke you may have to replace that whole plastic line or the line won't stay connected.
I just change the old purged valve and it did make that ticking noise and suddenly when I put the new one in it started to tick why is that
Genuine ACDelco part?
Is it safe to assume this would be covered under the drivetrain warranty?
The initial GM new vehicle bumper to bumper warranty, yeah. Past that unlikely, the solenoid is usually considered a wear part like a filter, gasket or seal.
@@DrShock if I just let it go, will it harm something? I only ask cuz I'm not very Teck. And I have warranty.
@@MatallicA35dozer It won't _harm_ anything per say. You'll eventually get a check engine light and in some states you can't pass inspection with that condition. And depending on how the unit eventually fails, it can fail in a state making for hard starting conditions. But it won't damage anything, you just need to get it fixed when the time comes. Most folks don't even notice the sound, and only realize there's a problem when the check engine light pops and they get the code.
It's annoying sounds like a engine knock lol thought the old lady blew up the car then I found it was coming from the purge valve
why you not turn on engine after replacing it to hear if ticking sound has gone or not
Of course this was done, but not filmed because I already showed the test at the beginning. Trust issues? ;-)
@@DrShock I asked you to start the engine because it doesn't always work. In my case I changed it to a new one and the ticking sound continued. Then I took the car to the dealership and he cleaned the tubes connected to the evaporator and reprogrammed it according to what he said and the sound disappeared. Now it works fine.
Does this cause a MIsfire this part is ticking for me and I have a misfire
This part would be one of the _least_ likely to be involved with a misfire condition. Diagnosing a misfire can take some time as there can be many many causes for such an engine problem. Definitely not a parts cannon fired into the dark candidate, can get expensive real fast just throwing parts at it. Start with the diagnostic codes being recorded for the misfire, and run thru the troubleshooting associated with each code stored in the engine computer.
Can anything bad happen if we just ignore it and keep driving for let's say, another 50k kilometres after this symptomps have shown up?
At this stage, where you have no trouble codes posted, it's just a cosmetic type of problem and nothing to be concerned about otherwise. I've mentioned in other comment replies that these solenoids are never _silent_ and make some sound through normal operation. It's only when you can detect the sound is no longer _normal_ that this video is about.
@@DrShock thank youu! I thought this would affect my fuel consumption or performance, but maybe I should clean my throttle body/injectors 😁🙏🏻
How long before the replacement did the same thing?
You should expect an ACDelco OEM unit to go for many years. Remember there is supposed to be _some_ sound, it's a solenoid afterall. It's just when the sound becomes excessively noticeable with the hood closed that you can proactively address it.
@@DrShockIf it works, I don't replace it. They are loud inherent to their design. Most companies surround them with rubber along with the rubber mounting them to the metal bracket. Helps to bring the noise down. Placement of this valve also makes a difference. A lot of them are under the intake or somewhere tucked away.
The Cruze is an econo box, so they cheeped out on the purge valve.
nice video mate. I am not mechanic but would i be able to replace it my self at home because my mechanic want to charge me 60 pound. by looking at ur video i dont think is 60 pound labour. i have vauxhall zafira tourer turbo engine. would i be able to change it myself?
This one is definitely a DIY project with no special tools required. Just be sure to put the $ saved into the OEM part and not the inferior imported aftermarket versions.
i always buy from main dealer. would i need to clear the code after fitting? PO171 system too lean bank 1. is this the cause for Evaporation purge faulty?
That particular code, for this specific GM engine, is rarely associated with this EVAP solenoid. That code has a number of possible causes ranging from PCV oxygen sensor and would need specific diagnosis to determine which. Code P0496 is more commonly associated with the repair this video is going over.
thanks
my mechanic said i need to change Evaporation purge. ur advice should i go ahead to replace it or not. the part alone cost around 100 pound.
Thanks for the video..its awesome !!
Btw, what will happen if we not replace the Canister?? It just make an anoying sound or it can make the engine damage ??
Thanks. No, this noise problem causes no damage if ignored. Eventually the solenoid will fail to operate properly and cause a check engine light in the instrument cluster to come on. The solenoid is part of the emissions system, to reduce pollution of the air we all breath. Once the check engine light is on, it is a repair that you will have to do at that point to pass state inspection, if your state checks the vehicle for emissions compliance.
@@DrShock Beside reduce the pollution, that part can affect the gasoline consumtion?? Maybe, it can be more economic..
Nah, not on this GM engine. Only emissions. Of course if the vacuum hoses going into and out of this part are damaged/open, that could lead to driveability issues but that's unrelated to the EVAP solenoid function itself.
Can this cause check engine light to come on?
When the solenoid fully fails, yes it will usually trigger a trouble code. But not in the early stages like we see in this video.
Why did u not Start it to show the clicking gone ?
Just ran out of time with the cars owner needing it back, as mentioned at 4:55. It's a pretty cut and dry diagnosis here as shown with the harness disconnect/reconnect test.
Just remember that there's always ticking with an Ecotec 1.4L. And there is some sound that _normally_ comes from an operating purge solenoid. It's just a question of _abnormal_ ticking that you might notice that was *not* there before. There are several sources for such new sounds, this is only _one_ of the possibilities.
Changed this part because I have a 14 cruze with exact noise. Noise still continues... what can also be the problem ? Or what should I be looking for?
The before/after test I show is to help determine if _this_ is what you're hearing. The part is not silent, even when operating correctly. But you shouldn't be able to hear the genuine GM/ACdelco solenoid with the hood closed when operating normally.
There's a basket of other things that can cause a ticking (besides the fact this particular GM engine has a _normal_ ticking to it to begin with). Exhaust manifold leaks or lifters are other possible _tickers_ that can be heard over the engine noise.
Mine still clicks loudly
I always thought that was just my fuel injectors being loud 😭
How much for that part? My Trax with 1.4 is making that noise.
There are links in the video description where you can buy.
The first time ever I've seen an American work on, to them, small European engines.
I replaced the purge Canister but it still making the noise. What do I do?
When you did the unplug/plug electrical test I showed, before replacing the part, did the sound change? That's an important diagnostic confirmation step, because there are other things that can sound similar. So you have to confirm the purge solenoid is the source of the sound, or at least one of the sounds, before you change the part. Like I mentioned in this video, we had actually had two failures to remedy before we got rid of all the ticking. This is one of them though.
@@DrShock I did that and the noise stopped, I think that I maybe got a faulty part.
Yeah, that's what I would suspect if the unplug/plug test confirmed this was the point of noise.
Question: What is the function of this part?
This is a solenoid related to the emissions system of the engine, to meet US EPA regulations on pollution. It is a system required to be maintained in working order for all states that perform motor vehicle inspections.
@@DrShock thank you.
Can this cause a rough idle?
Possibly, though there can be a multitude of causes for that symptom. Start with checking for vacuum leaks across all the lines.
I'm having same problem is it bad if i don't replace it?
At the stage I've shown the issue in this video, it's purely cosmetic acoustically. Eventually, the solenoid will fail completely and the check engine light will come on in the dash area. You could certainly wait on this sort of repair if it's only in the early cosmetic stages.
@DrShock i detach solenoid like you did but the noise still it's not too loud you can't hear it from inside or outside and no light on dash yet
If you hear the noise with the solenoid disconnected, that's not where the noise is coming from. ;-)
Will this give me code p0420 mine is clicking like that slightly but i have the code, car only has 22k on it 🤦
When these fail, it's usually a P0496. But you could have more than one issue going on.
About how long will I be able to drive my car with it sounding like this?
This particular problem is totally cosmetic noise, you could let it go until the part ultimately fails where it will then cause the check engine light to come on. Then you can replace it. Most folks don't like the cosmetic noise though, and replace it proactively just to address that.
Would be nice if we could take our broken parts back to Chevy to get the part reimbursed. I heardvthis is a recall part and covered, even outside the warranty.
Only certain years/VINs got something warranty wise - you could check if yours was included with the info here th-cam.com/video/UNqQ_egsbas/w-d-xo.html
Mine ticks some times then it stops.. even after I replaced the valve
They are not totally _silent_ when operating, but should not be loud enough for you to notice with the hood closed. At least the genuine GM / ACDelco ones are like that. Aftermarket ones will always be of a lower quality construction (that's why they are cheaper), so _may_ be noisier even when operating normally.
I just bought a 2020 sonic about 3 weeks and it has this noise already. Can someone tell me if this is normal and if not, should i give back and claim my money back? THANK YOU
It has 43k miles
Like with some of the earlier comments, those new to the Sonic and GM's Ecotec 1.4L turbo may not be used to the ticking sound it makes _normally_ by design. You have to go thru the diagnosis I do in the video to see if what you have is an _additional_ ticking noise caused by this solenoid on its way out.
A failing solenoid would not be covered by warranty usually anyway, as this is a wear item like a brake pad. They are relatively inexpensive, and easy to replace yourself if proven to have been the source. Only use genuine GM/ACDelco though (part info in the description), the aftermarket import parts will fail very quickly.
I also have a 2020 Sonic. It is not a super quiet engine. These engines are not like the older, quieter V-8s we used to have. They sometimes run and sound like lawn mowers. But did you get rid of that ticking sound?
How much is that part ?
Links in the description
What would the easier name for that peice be? Would it trigger code P0171?
I replaced it and it's still making the noise what else could be.😢
You did the electrical test before replacing it as shown in the vid to confirm the sound source?
I have a similar noise coming from my 2016 Malibu 1.5 EcoTec, wonder of this is it. But it sounds like a high pitched knock when heard up close
GM engines can each have their own unique acoustic signatures, but it will have a similar design. The EVAP purge solenoid for the 1.5L looks very similar to the one I'm showing for this 1.4L. You might give it the same simple electrical harness disconnect and se if the noise changes. Always familiarize yourself with how the connector unlocks and disconnects with the engine off, before trying such a test to avoid damaging any parts or connectors.
@@DrShock I will do that, first I have to find the location of where the part is. And I went on a trip last weekend & it was barely noticeable after a long run. Does the cold affect it too?
@@BruceLayR8 The temperature of the part under the hood, rather than what the outside weather is, may affect the sound. The ticking may not be as noticeable until things warm up, for example. But once it starts making the noise, it should be fairly reproducible from there on out.
I replaced mine and it’s still clicking loud
Did you use a genuine GM ACDelco part? Did you perform the test shown in the vid?
First of all, anyone know what causes them to tick? Just changed mine today. Old one ticked until I unplugged it. Put a new one on made by Dorman same as old one. Plugged it in and same tick. Just learned if your going to replace this part buy an AC Delco one. Going to try that next and hopefully have better luck but that's what I get when trying to save a buck!
#1: check your oil levels.
I should’ve done this first.
Yep, all kinds of causes for sounds. That's why I show the unplug test right up front. If the sound doesn't change, you have to keep looking.
EGR Valve
No, *not* the EGR with this engine.
Dont take your car to the dealer 520 bucke .
Got a system too lean code and I got this exact issue. Does that make sense?
It wouldn't tick when first started (cold)?
Is it safe to drive with this? Or should I get it repaired immediately?
Yeah safe, it's only an issue if the noise bothers you until it fails. Once it does fail, and it will once this sounds starts, the check engine light will be on and you'll have to repair it to pass inspection in most US states.
Много жрет бензина и вазможно глушения холостом ходе даже если вы в пробке стоите,поставите новую acdelco и замените топливу на другую компанию
I replaced mine noise came back occasionally a few days after
I replaced this part but it still ticks
I just replaced mine with a brand new one on my 2012 Ford Fusion SE 3.0 V6, and it still makes a clicking noise.
I replaced mine and it's doing the exact same thing. I found out it's not a simple on/off valve but operates on a duty cycle so it will tick like this when functioning correctly
Anyway to fix the part? I'm from Egypt and local suppliers sell it for about a 100$. And if I try to import it, it's gonna take a month and cost about 70$ after import fees and taxes.
My gm 2 series ecotec has severe flat tapet lifter tick
It's best to do it without the battery connection and replace it sensors at the same time
I just replaced mine and the new one clicks
Do you have a paypal? This saved me $ would like to send a couple bucks your way.
Thanks, check the description there's a ko-fi link. Or tap the heart in your TH-cam app.
That is not the cause. That is the effect. The cause is over pressure with breaks the valve that is ticking. Your timing chain is lose. Just wait for bad cold starts.
That's how it's supposed to sound anyway.. there's nothing wrong with it
Wrong answer for this particular GM engine on this particular GM vehicle. They are not completely silent as I've mentioned previously, but they are not supposed to be this loud either. The increased noise is an early sign of a solenoid worn out and soon to fail further. Thanks for commenting though.
@@DrShock The thing is I replaced mine with a brand new one and it still makes the same noise 🥲 very annoying
Don't waste your money 3 weeks tic tic again
