- Thank you once again for tuning in to Super Mario Diagnostics!
I've got a quick diagnosis and fix on a hard start. It arrived with no check engine light on, but nonetheless I scanned for codes and it gave me some direction.
The vehicle is a 2012 Chevy cruze.
The main code was P0496- purge during non flow.
I hope you enjoy, like, share, comment and subscribe!

Kept bugging my husband about this issue and he never fixed it. I showed him what it could possibly be and I was right! Then, I came across your video and decided I should try fixing it myself. It worked😁 Thank you for sharing your video and being so thorough❤
Thank you Mario! I thought it was a simple fix but I’m glad I got to see someone with vast experience approach the same issue I had.
Thanks for the kind remark Mazen!
Excellent and thorough explanations for the cause of the problem which many Cruzes have with P0496 . It fixed mine too. Thank you!
My 2015 has same code number problem with same noise ! So I will put it on myself ! My husband has always showed me stuff about cars since we were dating 23 years ago so I love sticking my head under the hood ! I joke to people that I am a car mechanic because I have some knowledge ! Great video !! Great help ! Thanks!
Haha that's awesome! 😄 very cool. Let me know how it goes.
You know my mechanic who I thought was a friend quoted $300 for this job saying it was really hard to get at ! Many thanks to your video I solved the problem in 15 minutes and part was only $23 canadian !!!! so cool keep up the good work
That’s sad . Glad you worked it out !
Thanks for the information. Perfect. Took 5 min. Cleaned codes and working perfectly.
It was an easy part to get to, that's always nice. Great diagnosis.
Yup, if it wasn't for access I would've had to whip out the vacuum pump. Thanks Wyatt!
You just educated me and saved me money! Thank you my friend.
The toughest part of the jobwas the red clip...🤣🤣...good job....
😂😂
Great video as always . Just be sure to note the direction of the purge unlike I did 😂
Thanks for checking out my channel Keith! Haha the farting noise video? If i remember correctly lol i did get lucky enough to get a purge valve with the intake hose assembled already lol but yes i can't say it hasn't happened to me before 😆 once again, thank you Keith, much appreciated buddy
😂 oh yes, I recall that video and the purge fartelnoid valve.!
I realize this is an old video but I always start from the beginning. I work for Mazda. Our skyactiv non turbo vehicles have a normally open purge at idle. Has something to do with lack of engine vacuum. However the turbo models are normally closed like most. If you are seeing a PCM command on the solenoid I would check for fuel saturation in the canister. A stuck purge is one thing but when it is commanded to open. The PCM is telling it to open for a reason. I found one vehicle we have a few years, (I think I was the first in country to find it) has been doing this. I checked live data and found the PCM commanded purge to be open on a normally closed purge at idle. I pinched the hose to see if lean fuel trims would correct which it did. We swapped out purge and same thing. So now we can say the purge is fine. Pulled down the canister and sure enough filled with fuel. Replaced fuel trims repaired. I know that chevy cruze is known for purge pattern failures tho. The ticking gives it away. Never looked the command tho. from PCM. Might want to dig on that especially if a full tank. Customer could have overfilled causing saturation.
I learned something new today. Thank you, helped me out a lot and was so easy.
This was the best video i could find on this issue. Thank you!
I just found it as well and you are soooooo correct! I've been dealing with this crap for 2 weeks and this video just answered my prayers!!
Great Video - Always wondered what that clicking noise was - always thought it was a tapping valve or the fuel injection solenoids!!
On VW's I often hear them at idle... sometimes nothing for quite a while, then on again for quite some time. I never worry about it unless I have an EVAP code or a rich/lean code. Nice to see that other manufacturers also have issues with sticking purge valves! =)
Yeah always good to know if it's strategy or not. Thanks for dropping in Thomas 👍
And I was about to replace my valve springs and lifters😂 thank you so much bro!
Ticking noise? Did this fix it? Mine is doing this
Good information. My 2012 Cruze has P0170 Evap cap off? Intermittent. Still seems similar. Runs ok. Detected in firing test. Thx
Oh man thank you!! I keep getting a p0171 and replaced valve cover and MAF with minimal improvement. You just made it clear as to what it is!! It is intermittent. I would bring it home with it spitting and rough idle and CEL. My girl starts it up and no CEL AND driving beautiful. Thank you again!
Omg having the same issue!! Glad to see this fixed your problem. I am ordering g the part now!
@@9Brandi4 still running great! I hope it helps you as well!
@@chrissnyder3430 i replaced this 2 times but popped up as p0171 this time instead of other purge valve code
Holy cow! I just told my girl it seems to not want to start when i get gas. You just said why at the end!! You have no idea how happy I am now!! Lol
I've been seeing purge commands at idle on a lot of them too, I think it is normal for the most part to have a small duty % at idle on newer vehicles at times when warm. Don't know why, but like I said, I've been taking a peak at purge pids on every one I hook up, to see what is normal and almost every make/model seems to be doing it. I chased my tail on a Chev Impala once with a perfectly normal purge command at idle once and after becoming frustrated I ended up shipping it down the road wondering if she'd be back again, never came back with any issues and that's why I remembered coming to the conclusion that it is normal as well as looking at other known goods. Good video Mario, thanks!
Yep I've been taking notice ever since, perfectly normal on modern cars. Thanks for watching bud
@@SuperMarioDiagnostics GM pruge valves fail ALOT, I wonder sometimes if it is just cheap design or if over fueling has a lot to do with it. I know faulty charcoal canisters can cause damage, but I have not found anything wrong with canisters on 9 out of 10 failures...so who knows? Must just be one of those things.
Hmm i couldn't say, i don't see it often enough to come to any conclusion on the matter. But interesting observation
Very good video. Camera is right where it should be to see well. Thank you guys!
🛠️ NAILED IT...Great Job Mario on a quick and effective diagnose. 😀
BTW If your still wondering about the 17% command purge, I wonder if it has something to do with that other code. The P1101 (Dirty Throttle Body issue) and I would bet the TB idle compensation was high along with TPS % slightly upwards. Therefore it thinks your on the throttle. Just a thought..actually more of a guess since we didn't see any data on this one.
🍻 Cheers Bro 😎
Makes perfect sense, yes a dirty throttle body will set off that code, but so will any discrepancy between calculated airflow vs actual(vacuum leak, or dirty throttle body). So no I didn't film any idle compensation data. Nonetheless great food for thought. I'd that's a pretty accurate guess. Thanks for chiming in Kevin!
Thanks brother this just saved me a trip to chevy.
Thanks man. I just installed mine. Easy Breezy and saved some Dinero$$
Make sure the old valve doesn’t have pieces of charcoal in it from the canister or it’ll be back with the same problem. Great video.
You're absolutely right, glad you mentioned it. It was as clean as a whistle 👍 thanks Che, glad you enjoyed!
I make same questions specially in hyundai kia that is a common problem and sometime with hyundai kia it get a no flow trouble code and the problem is aftermarket purge valve fail to open at low duty cycle %. Good videos man
Yep they are very common
My 1.4 cruze is making a similar noise, but I checked this and it's good. Then I pulled the dipstick and the rattling/ticking noise gets louder from the intake manifold, so it's the PCV valve in my intake manifold!
Yes why was it commanding 17% at idle , interesting . On my F150 it would command to open on a decel intermittently and stall the engine. The dealer said its impossible to enrich it enought to cause a stall. Ooops they were wrong . Took me from 2010 as new till last year to find it😅😅 oh ya I'm that good. Keep at it Mario , this was an awesome vid and will do well. Cheers
Yeah, I kind of think the codes seeing may have something to do with it. Haha impossible?? No way! At least you got it Steve! 🤙 your comments and support are always appreciated buddy, hope it helps anyone who might cringe at this triple code whammy. Thanks again Steve!
It commands Rich because once the canister is deplete of any fuel vapor it will then become a standard vacuum leak like any other. More air than fuel. 😉.
New Level Auto hmm I would understand what you mean from a fuel trim standpoint(vacuum leak). Can't say i understand what you mean in this particular case though 🤔
@@SuperMarioDiagnostics I was attempting to answer Steve's question as to why it was commanding 17% fuel trim
The 17% was in reference to the purge command at idle. I never showed or mentioned fuel trims Keith 😂
Do you have an idea as to why I keep getting a p0171 instead of the p0496? I have been hearing that ticking as well when I raise the hood. This is just blowing my mind. I wish I would have known this 2 weeks ago! Thanks again!
The ticking is normal operation. As for the p0171 after the fuel content has been depleted from the charcoal canister(which may not take long), it then sucks in air, since the vent valve is open. This leans out your mixture and sets off a lean code
Thank you. That makes perfect sense.
Thank you! Very good tutorial and troubleshooting...
Hey great video! My 2012 is having a very similar issue. First start right after filling had no issue. Second start at home was rough, then died. Now it won't start at all. Is there anyway to test the valve without the car running?
By blowing through it. No air should pass when disconnected.
Did the engine ticking go away to? Great job!
Thanks Much, Mr. Super Mario,you are very accurate,you just save my skin, thanks for share,there it goes my thumb up,and you got another subscriber
Great video! Thank you for sharing! Thumbs up!
Hey thank you for checking it out and commenting, truly appreciated!
Awesome video... Thank you for your help!! 5 STARS👍
Mine popped off the driver's side!! How hard do I need to push down to secure it in place?
Can the red clip be bought separately, the one on my daughters car is missing. Also, what is that line called the the red clip is on? Thanks in advance
Great video and confirmed issue I am having.Thanks.
Is this under the engine bay or where would the purge valve be located?
So these purge values are gonna click even when in perfect running condition? I feel like I can hear it so well because I have extremely good hearing. The car has no issues starting up, no hesitating at idle, none of that. The mechanic was looking at it with me and he said it was normal or the injectors(still normal). Mine is a 2014 chevy cruz.
Correct, they are loud. But they tend to get louder when failing. You may not feel any symptoms until it gets past a certain threshold. But yes in perfect conditions they click at idle and when cruising
@@SuperMarioDiagnostics Thanks for the quick reply and thanks for taking the time to upload these in depth videos. You're a huge help to everyone 💪
Looking at fuel trims, whenever I hear the valve tick from the cabin, the trims go lean. Then it stops and goes back to stoichiometric. I have a 2016 Ford Focus. The ticking problem has been discussed online. Rough idle accompanies it, which I'm seeing. I'm 98% sure this has to be it.
Yes I've since seen many more of these and its normal. But go back a couple of years and you wouldn't see purge valve opening at idle, it's more of recent thing. Plus every make and model is different, it can peg both lean or rich depending on how full the canister is. Thanks for watching!
@supermariodDiagnostics I replaced mine today step by step with ya video...still ticking.. 2016 Chevy Cruze limited lt..any ideas or thoughts?
The ticking is normal operation, the concern is that it's open during non ticking, and causing a lean running condition
Super Mario Diagnostics maybe wrong gas? I put in premium... I have a neighbor that has the same car and no ticking.. it’s louder now.. maybe time to trade it.. I love the Chevy Cruze..
The ticking is normal. Unless you mean the engine is ticking
Super Mario Diagnostics nope it’s the same part I replaced.. vacuum test is the same.. maybe bad part.
So you vacuum tested it while disconnected electronically, and vacuum gauge connected on the fuel tank side?
Can I fix the ignition malfunction before replacing the missing catalytic converter?What do you think is causing the ignition surging/cycling/skip and is the Evap purge valve involved? Most of the restoration of this car I performed myself, and I have not found the answer even with other mechanics basic diagnosis.
Hello Super Mario, I recently bought a 2000 Pontiac Firebird 3800 V6, AT, electronic throttle body, 3 cat snsr's, / stock except for deleted catalytic converter (2 O2 (L + R) upstream/1 O2 down stream/disconnected).
Replaced Plugs & wires, ICM, 3 coil packs, fuel injector #4, fuel, air, & oil filters, Fuel pump, Emission Evap Purge valve, but still click loudly like in this video but there is a misfire like condition where the engine misfires & or surges like every 3-5 seconds this occurs randomly and disappears randomly occurs mostly when warm. Runs strong and smooth except when it starts this cycling issue; it still has power but cycles/misses/?. The Evap loud clicking is louder while this condition occurs and idles with a repetitive vibration occasionally simultaneous to the condition, mostly after warm up and a drive.
Diag:
- I bought a cheap code scanner and keep only getting P0140 (O2 Circuit No Activity Detected, Bank 1 Sensor 2) due to the missing catalytic converter and disconnected O2 downstream sensor.
-I took my car on a road test (0-70 mph) with the tool and all of the online readings (O2 sensors trim levels, throttle, air __, etc seemed within basic operational parameters according to multiple ref. sources). Anomalies: Status changed from CL (closed loop?) to OL overdrive (open loop with car in overdrive?) during hard accelerations only. CL is the norm. I understand that the ECM should control all the major ignition operations when the engine is warm and conditions are normal.
I took my car to a couple of mechanics who stated they wont do a full diagnostic till I get the catalytic converter replaced. I have 2 year of auto mechanics classes manys year ago, 2000 Chevrolet Camaro & Pontiac Firebird Service Manual Volume 1.
Also could not detect any vacuum leaks nor bad electrical connections under the hood, also had the fuel pump replaced. The car originally had 2 other codes solved P0301 and P0304; they stopped after replacing the worn ignition components including #4 fuel injector. Also the fuel gauge misreported fuel just after the fuel pump replacement 10/2019 lately reports accurately even when very low.
Just am financially (work) recovering after natural weather disaster Berkeley Co. SC and will get a new aftermarket catalytic converter and a downstream O2 sensor replaced new later this year. Just had my only other car break permanently during 2019's Hurricane Dorian.
Going in open loop during hard acceleration is normal.
When you disconnect the purge valve, all clicking goes away?
when in open loop, does it continue to surge?
Sounds like when it's warmed up and gone into closed loop, that's where your problems start.
What are your fuel trims at hot idle, and when you slightly rev it up where do your fuel trims go.
Sorry but is a basic code reader all you have to diagnose this? Do you have an oscilloscope?

Happens to me right after fill-up 113k miles same make and model and year now I wonder if mine has this issue
i need a good mechanic like you 👍
Quick and easy. Thanks!
Thank you! 👍
Is it 4 or 7 fuel injectors I need because I replaced this piece and my check engine light is still on
I suggest diagnosing it before throwing parts at it. I showed exactly how to test this, and you are required to clear the check engine light yourself. What codes do you have?
Any more 2012 chevy cruze videos? I keep having a weird smell coming out everytime i turn on the AC. Have you came across anything like that before?
Change your cabin filter. Sorry no more videos yet
Thank you bro
No prob
@@SuperMarioDiagnostics hey would you know why coolant temperature goes up but then goes down as I'm driving and then goes up once I come to a stop on a 2012 Chevy Cruze
Sounds like your radiator fan might be weak or inoperative. The air from higher speeds coold the engine, then when your idle there's no air to cool
Thanks for the video
Fairly new subscriber! I’ve seen 2 videos so far. Great content. & great tip on the alternator bushings for cardone!
Thanks angel! I hope you enjoy buddy!
Just educated me and saved me money thank you 🙏
My granddaughters is a 2016 I got the same code I replaced it code didn't go away . I cannot blow air through either side of that valve but it's disconnected so it's not stuck open I know what's going on
Video was great. Made easy to follow.
Thanks Bill, glad you enjoyed! 😃
Great video.. thanks for taking the time.
Good job bro....you did well👍....Can be really tricky with some diags nowadays, always something to test us....and even more stupid 'trick' clips and connectors than ever!!🤬...keeps our brains working I guess....lol🤣👍🇦🇺
Is this "hard start" only the first time you try after the night? And then you can start the can any time with no problems?
i have such problem on my 2008 kia optima 2.4l but i have no diagnostics or pico
The customer did not make it clear whether it was after an overnight. The symptom did not occur with us, so ultimately i relied on the codes retrieved. Which aligned perfectly with the info the customer DID provide. Now as for a hard start after an overnight. You may want to keep an eye on fuel pressure. Maybe even the coolant temp sensor. Loan a scanner from your local auto zone or other parts house and check your live data for any anomalies. A disconnected ect sensor can fool the ecm into enriching the mixture so much that it creates a long crank time, but when the engine is warmed it may be less affected, since it's already warm
Mine was always after fueling. Replaced the purge solenoid yesterday and it fixed it.
Hey thanks for the helpful video
I have the same car... I’m at 92,000 ... my check engine light has been on for months and the code reads Emission Evaporative System... not sure what that means I’ve heard the ticking sound as well ... could they both be the same
Which code exactly? The ticking is normal operation of the purge valve, it does not necessarily mean it's bad, i show exactly how to test it here with no tools, by disconnecting the electrical connector to the purge valve while the car is on(will throw a purge circuit code) and removing the fuel tank side hose, and checking for vacuum at the open end of the purge valve.
Code P0171 System too lean (Bank 1)
Code P0496 Evaporative Emossion System High Purge Flow
Ok then in that case id do the same checks in this video, but more than likely your purge valve is stuck open.
Super Mario Diagnostics ok thank you .. I will check
Was the code the knock sensor? Thanks
Mario really is Super .Nice VID my friend.
V4VAUXHALL haha thanks!
Is there any videos for the solenoid on the tank vent canister I cant find any
Thanks for the vid..awesome job
Some solid diagnosis 💪
Thanks Jonathan!
Bien trabajo ese . Que Escanner usas gracias Lol
Gracias lol. Estoy usando el maxisys 908.
How do I replace a 2012 Chevy Cruz Evaporator emission control valve replacement, OK
When changing or check if it sucks your finger ... do you have to disconnect the negative battery cable ?
Soweird Harris no, the engine has to be running
The shop that changes my oil told me this code was why my check engine light was on. I replaced the part myself but the check engine light is still on. Will it go off on its own eventually or do I have to clear the code. Or could it have been another issue causing the code?
Without any testing involved it would be impossible for me to say whether you fixed it or not. You're better off having someone clear the codes for you. Just about any auto zone will do it for
@@SuperMarioDiagnostics the check engine light went off by itself. Thanks!
Thanks, very helpful
Pocket screwdriver prying is the best! 👍
It's gotta one of my most used and abused tools ever 😂
Ditto! Lol
good job Mario very thorough
Thanks Dwight!
Great video bro thanks you save me so much money
Exactly what I was looking for and didn't have to look far soon as u said acts funny when fueling
Give the clip a good squeeze and no flat head screw driver is needed. Plus the red clip goes on last from the bottom and the shorter part on the clip goes on the underside of the passenger side. Safest way to not break the clip. Cause it will if your not careful ha
What kind of issues will this problem cause other than the obnoxious clicking sound?
No starts after filling up
Good video brother. Don’t ya hate it when your gloves tear? 😂 Tech struggles...
another great video got the same code today at quiting time i no where to start tomorrow thanks
Glad i could help buddy
@@SuperMarioDiagnostics you always do
Purge valve replacement didn’t work. There’s still lot of noise coming from the new purge valve. Any ideas on how to fix this issue?
-Code shows P0420
-2012 Chevy cruz LT 1.4L turbo
The issue is not the noise. The issue is that it's leaking while it should be closed.
Code P0420 is unrelated to this, I think you should take it a professional automotive technician.
I just bought a 2012 Chevy Cruze with the 1.4 liter turbo and it makes that clicking noise also does that mean the purge valve is bad
These have very loud purge valves. I wouldn't worry about it
@@SuperMarioDiagnostics Ok thank you and Merry Christmas to you and your family.
Merry Christmas, and happy New Years to you and your family 👍
I have a p0171 code and p0496 code i already changed the purge valve but the car doesn’t want to start what can it be?
Was this on the 1.4 turbo or the 1.8?
Hi.i think im having the same issue but dont have a scanning tool.
wouldnt a simple test be to block the purge valve and go for a drive
Not really. That will set off more codes.
did the clicking go away after replacing the valve?
They do click ..its normal.. start yours up and remove the left hose...then place your finger over the valve body opening.. if it sucks your finger, its bad.
Nice video
After the purge valve is replaced, how long before the check engine light goes off?
Could take a long time. I suggest getting it cleared
@@SuperMarioDiagnostics who would I take it to to get it cleared? AutoZone won't clear them anymore
Any auto parts place should clear them. Weird that they wouldn't. I can see why though as it makes the mechanics job harder. Let them know that the cause has been fixed and that you want the code cleared
Good job
Dude, I absolutely can not get the new one to connect into the manifold. Everything else hooks up just fine but it just won't pop into the manifold. Any suggestions or know the reason why?
Find me on Facebook. Message me. Facebook.com/supermariodiagnostics
I ended up getting it popped in. I let the engine warm up for a bit. It's pretty cold here. Lol. Thanks for the video and quick reply.
Awesome, you are welcome!
What's the fuel pump pressure Sonic 1.8?
Great video 2013 Chevy cruise the dealership wants to sell the whole unit with the manifold connected they say they cannot replace purge valve by itself why is it that you were able to remove it and they can’t remove or buy just the purge valve by itself without replacing the manifold and purge value 600 $ Plus labor looking at $1000 to do this job that’s what they want to charge the part only cost 33.99
Good thing you do your research:)
Thanks for watching!
Ram M457 they are trying to rip you off. show them this video, then tell them what they thimk...
Could this issue also call for cylinder 3 misfire along with evap code? This fkn car has got me bugging!!! Ive replaced battery, coil pack, spark plugs and now all new injectors. Still same shit
I have the same code. How much would this cost at a shop if I were to decide to take it in instead of fixing it myself? Ball park.
Having the same code wouldn't necessarily mean that it's the same culprit. A diagnosis must be performed first. I only show a testing method for one possibility for this code to set. I've no idea what they would charge you. Too many factors contribute to shop labor times, and diagnostic fees.
Super Mario Diagnostics , you’re quick. So I did get the same code with the same diagnostic but also there’s lots of leakage from timing cover tranny seals. I don’t know what that means, but Thanks for the video though, it was helpful.
Is it also a Chevy cruze? Have any parts been changed yet?
Super Mario Diagnostics. Nothing’s been done yet. I picked it up from Wheel Works just now. They told me they couldn’t fix it there, so I was just doing research.
Super Mario Diagnostics it is a Chevy Cruze 2012.
Meaning dirty gas / ethanol, which is alcohol base water.
Great video
Question, will the engine light turnoff automatically?
After a long time yes. Or any parts place will clear it for you
Super Mario Diagnostics I just replaced this thin3 years ago and its acting up again, thank you for showing me how to do it myself because honestly I can’t pay Chevy 200$ + at this moment
No problem, they are a high failure rate item. Please did testing first prior to condemning this part
Do I need to replace it?
Thank you!
Is it working?
Thanx for the info
Awesome bro
So, my brother's 2015 cruize cranks but wont start. He had a water pump go bad and he had a friend replace it. Few days later hose blew of thermostat housing causing him to lose all coolant. He immediately pulled over before car got chance to overheat. His battery died once they got everything back together and coolant in. Got another battery on it and the car will crank, but wont start. Engine light is on.
What codes?
I don't have a scanner, thinking about picking up the one that are $10 and Bluetooths to a phone. It's the engine light that is on.
Fuel pump is working just the ecm is not letting car run.
I hope they didn't blow any fuses when putting in the new battery. Gotta check basics, spark, injector pulse, fuel pressure. Is the security light on while cranking? There's a lot of things that can inhibit starting that a code reader simply cannot see. But you gotta start wth the basics
I did all those things, no security light. All fuses is good. I reset computer and car ran for about 3 seconds and the ecm killed it. I ran back over everything and looks like they hooked everything back up right except that hose on the thermostat houssing. It popped off on a highway with speed limit 75. Gonna get a scan tool from a friend. Im use to old cars 😂
