Does your Cruze door make an annoying noise when opening , this is my low cost fix . ua-cam.com/video/nU-RbOPq3Lc/v-deo.html
Thanks for the video. It confirmed my diagnosis and gave me the confidence to repair it myself. Now the car runs as it should.
Awesome Kory👍
What kind of car do you have? Also that’s good that he was able to help you! I have a Chevy sonic and fixin to do the same.
A ten minute fix and an 18 minute video. (ha ha) Paul's the best! Great to see you get back to working on a vehicle again.
LOL your moma never raised no fool 😅😅😅 Wyatt there's so many great teachers in the automotive field on youtube and Paul represents them all so very well. Cheers bud 👍
I have a 2013 Chevrolet Cruze LS 1.8 and did exactly this on your video. Thanks! It really worked.
Awesome 👍
I bought a 2013 Cruze for a $1000, so far, in order, I've done the rear shocks, the valve cover(pcv failure #1), the turbo and exhaust manifold, oil return line, oil feed line, coolant feed line, thermostat, coolant outlet housing(cracked during turbo replacement :(), valve cover(pcv failure #2), coil pack, and pcv fix v3.4. About $1100 in parts, no labor cost to me except the skin off my knuckles thanks to awesome gents like yourself. Thank you very much.
UA-cam is a great place to share and it's all free Nice to see you were able to do all that work yourself as you most likely save more money in labour than the purchase price of the car . 👍
So much better at explaining things then most other videos very easily understand
Thank you 👍
I bought a scan tool 10 years ago it has saved me money.
I have invested in some nice diagnostic tools and every peice has paid off very well . Knowledge is a money saver too just like the tools we invest in. Cheers Danny 👍
Good call!!! Isn't great when a repair works? That feeling, beating the machine! Love it
Hi Victor
I don't post hardly any repair videos at all but I actually do a lot of auto diagnostic but man I can't compete with Paul and Ivan or Eric and all the pro's out there that do it so much butter than I . I may do more in the future for just beginners like me 😅😅
Good morning Steve, great teaching mechanical point Sir and very well detail and Yes these scan tools are very well made ( each time that you go at the garage they will charge you min of 50$ of using their one 😤 ) Thank you for this very good gentleman ( Paul ) and have a great week end Sir Cheers 😉👍🍻
Cheers Dave , check out Paul he's very good .
Hi Steve, it's always a nice feeling when you fix it youself, nice tips. Cheers !
Absolutely Ron plus the lady appreciated getting her car fixed for free . Cheers bud 👍
Great video Steve - good work also on sorting out the actual issue. Scan tools are very handy in pinpointing the problem and in my case, I usually go to UA-cam for a fix lol - this video will help others so good on ya’ - cheers
Thank you , yes so many check out youtube for a fix . For me I so enjoy watching the channels that teach how to learn about how the systems all operate rather than just the quick fix . I know many find diagnostics challenging but hey if I can learn anybody can learn too 😅😅
If your intake system has a significant vacuum leak that's allowing air to enter at a point DOWNSTREAM from the MAF sensor and UPSTREAM from the Throttle body, this will allow air to enter the intake system that the Computer is unable to measure (because it's after the MAF sensor). The computer will measure excessive Oxygen in the 1st O2 sensor, and respond by increasing the Long Term Fuel Trim in order to correct the Air : Fuel mixture or Stoichiometry error (Lean Condition). Check to see if your Long Term Fuel Trim has been increased to +10% to +20%. The computer will do this in response to the unmeasured air getting into the system through that vacuum leak. The computer will also issue the "Operating Too Lean" P0171 code. If you think about it, this is the exact condition that the P0171 code was designed for but hardly anyone mentions it. Bear in mind that in a Turbocharger system, this includes the whole intake side of the Turbocharger so it's not going to be simple to find.
Thanks for your explanation and your patience
👍
Thank You. This video will come in handy. I'm getting ready to install a new MAF sensor on my 2015 Trax and hope and pray that fixes the problem.
👍
How's she goin'? I can remember when small engines used to stump me. Well by reading, trying and watching UA-cam I feel pretty confident now that I can fix small engines. I think it's the same for car engines. There is a lot of technology, detectors and other things on engines these days that make them complex, but if you watch and read and get an understanding of what you're looking at, repairing your own vehicle can be done and done safely. Thanks for sharing this video Steve!! Take care!!!
Yes sir , it's gaining the knowledge that puts money in your pocket instead of dishing it out for lack of knowledge. Give a man a fish or teach him to fish still applied today eh 😅😅👍
Thank you for your advise. I will be visiting Paul’s channel.
Hi Raul
I guarantee you Paul will provide all the technical, hands on instruction anyone could need for diagnostic.
Hey Steve,
Thanks for putting this up. 6:00 helped me determine my wife's 2015 buick encore valve was stuck open because it was sucking in air causing the too lean code.. Appreciate you taking the time to explain and upload this video.
Awesome , glad to have helped.
What valve was stuck open?
@@Zeek800 evap purge solenoid valve
He's helped me out before. Nice fix Steve, I bet this video gets a gazillion views
Paul's awesome, glad you seen his channel. GAZILLION EH 😅😅😅👍
Thank you so much. Best video I've found on this topic.
Thanks Jeremy , much appreciated 👍
Nice job on the repair Steve. Some people run themselves ragged chasing this issue. Cheers
LOL absolutely and a boat load of part too . Take Care Lloyd
Very helpful video and easy way to explain.. thank you
Thanks much appreciated.
True Gold.... also, check anything you changed on the vehicle recently. Understanding the cars needs. will diagnose problems. Thanks
👍
Steve always coming up with widgets, PAPA would just throw a brick on that gas pedal. Nice job on both fixes Steve, good info video! I have a scan tool, comes in handy.
Thanks bud much appreciated 👍
It is amazing how much of repair is simply cleaning.
Yes but so many do flip the coin and try a low cost carb expecting high results 😅😅 Cheers Pat
Thanks Steve,
I'm having similar problems with my 08 4runner..,0171,0174,0137 codes. I replaced the 02 sensor and the MAF but still getting the codes and rough idle and bad gas mileage. I'm going to check the throttle body that you are the first to mention,I hope that is the problem.
You are right about all the advice on you tube..,very confusing.
Thanks for taking a look Gene.
Thanks for your help that will help me out big time even took notes thumbs up
Awesome Joe .
Steve your just to cool ! I think you can almost fix anything! How to fix it the cheaper simple way and doing it right! (Same in medical care you have to fix 8 little problems maybe to fix or work on the bigger problem)
Annie I am willing to learn almost anything within my capabilities and great teachers are definitely the easiest path to sussess. Far too many shy away from auto diagnostic but do medical diagnostics all day long :) I'd like to see more on youtube take advantage of learning diagnostics and save themselves the money and time getting someone else fixing their auto. Cheers Annie 👍
Thank you for your help. Keep it up
Thanks Miguel 👍
Thanks brother i like your style cheap and get the job done and talk in a way i can understand i subscribed wish you luck brother
Thanks Derek much appreciated 👍
I subbed because your content is thorough. im working on a 2015 chevy sonic. suppose the cruze and sonic are the same vehicle. either way as you said the concepts should be the same for all fuel injected internal combustion engines. well done!
👍
Thanks really enjoy having someone explain shit in layman’s term
Thank you for tips
👍
Nice pointers.
Thanks Ron much appreciated 👍
Have a obd FIXD reader, you just solved the stutter at idle. Thank you.
Awesome 👍
Thank you going to Paul
👍
great video steve,i have a 2018 cruze 1.4 code po172.mass flo air senser cleaned.code doesnt always come on.i suspect a dirty fuel injector,so put some injector cleaner in there,so far so good.i will see what happens and if it comes back try cleaning throttle body.car only has 35,600 miles.
Intermittent's can be tough to find but over time they always seem to show themselves. Cheers !!!!
Nice job Steve!
My GF has a 2016 Malibu similar engine
She was getting these codes also so I went in and cleaned the throttle body real good and it was fine for 3 months and here it won’t autostart with the check engine light on so scan it and the same code so I clean it and all was good for about 3 months again
Go back in and clean it and it was due for an oil change so I went with pennzoil because I heard this was one of the better oils to use and low and behold it hasn’t come back on !
Car only has 50,000 miles I was starting to think the car had blowby or something…
I do believe there is a recall with some of these for the valve cover or something?
Anyways good info bro!!
Good investigating results . It's all about trial end error when dealing with intermittent concerns . Good stuff bud 👍
cheers mate
Cheers Joe 👍
Just seeing this now Steve! Thanks for the mention my friend.
Hi Paul
Thank you for providing the most reliable automotive videos that everyone can watch and learn from . 👍
hello what if your throttle body is brand new
my scan tool is coming up with P0171 and P1035
I would say your scan tool is directing you with codes to get sorted out .
I'm workin on my Bugatti, Lamborghini, Ferrari and McLaren...thx for saving me 5 bucks on cleaning spray.
Save tons of money in doing something on our own and feel a whole lot better.
Yes exactly plus the time we save not taking it to a shop . It's actually so easy to learn about auto diagnostics watching the right channels that take the time to teach. Cheers bud 👍
I've almost rear ended like 10 cars not expecting my car to keep going even when I brake, like a car outta hell but hopefully this and replacing 02 sensor finally fixes it( new maf sensor, cleaning throttle, new air filter and spark plugs didnt work)
👍
Did it work
Appreciate the tips thanks 🤙
Cheers Emilio 👍
What on Earth is a "Snow Brush"? Maybe to hold the gas pedal down one can use a folded-up sun screen that you always have in your car to keep the interior cool so you don't burn your hands on the steering wheel when you get in the car. 🤔
My car also has the p0171 code 1.4 turbo. Also oil coming out if Intercooler tube.
Thats not good at all. Time to start checking ✔
Ever figure it out? My very first guess would be to check the PCV hose. That will not only absolutely guarantee a P0171 code as well as fuel trim problems, but also can interfere with oil flow to and from the turbo. May want to also check the PCV valve itself like shown in the video. If turbo pressure is delivered into the crankcase from the turbo (in lieu of bad hose/valves on the hose) then it will damage the diaphragm of the PCV valve itself. A lot of people complain about bad PCV valves on the cruze, so much so that it was even recalled. But the truth is much of the time the PCV valve wasn't the culprit, but rather terrible hose designs used by GM on many vehicles. Coincidentally, all of these vehicles have this known issue.
Hello,
I've got P0171 and P1101 faults on my 1.4 turbo. I checked the non-return valve in the intake manifold, the oil separator membrane and the non-return valve in the turbo hose which was bad. I changed it with an used one, but it passes little air from the turbo side ( you can barely blow the air from that side in to the hose). My question is: should I bother to buy a new hose for 50eur? Could the system even feel such a small amount of air coming from the hose and turn on the check engine light?
Wow thats an expensive hose. If the check engine light does not come on and the engines runs well I'd leave it as is.
a lot of people have a scan tool but don't understand the data and purely rely on the code is the part to replace
Exactly , I have been asked so many times to replace a part because the code mentioned a part they recognize :) Jerry the auto parts stores could never survive without the parts changers out there LOL Take Care Bud.
@@SteveRobReviews I tried explaining this to a girl a month ago. I told her I wanted to diagnose her car and see what was actually wrong rather than just changing out the part. She sounded worried and panicked when she heard diagnose and never got back to me, I don’t blame her because she’s probably heard horror stories of mechanics ripping people off or she’s experienced it.
Some know how helps, and now we know. :) That would have cost big $$$$ at a dealer, they would have replaced all new.
The dealer does a great job at fixing vehicles so they never come back with the same fault and replacing parts is a great way at doing it LOL
Can an aftermarket cold air intake cause a lean code due to the new air flow?
Anything not stock can have odd drivability faults.
Great job bud. So did you get Xmas cookies for payment lol. But your right, lot of the time it can be fixed without fancy tools. Cheers
I never charge for working on friends and family members vehicles but I always seem to get a case of beer 😅😅 Thanks much appreciated 👍👍
I'm frustrated. I replaced the O2 sensor, spark plugs, ignition coil, fuel injectors , valve cover, and I still have the same problem, rough idling. I cleaned the throttle body and it went away but came back three minutes later. Do I need a new throttle body ? 2014 chevy cruz turbo. The code finder showed about 4 codes
Elizabeth, what are the 4 codes.
Could be your PCV valve there’s a circle in the top right of your valve cover it you cover the little hole with ur finger and if your engine tweaks it’s your valve cover because your pcv is built in with it
That thing on the valve cover is not a PCV valve it is a part of the system. The main culprit is in the intake manifold. The PCV is actually a small orange rubber? Diaphragm that either disappears or is “ there “ but partially leaks. Chevy should have fixed that issue but just kept selling intakes and valve covers that just ended buggered up again. There’s a kit on another site ( look for Cruze kits ) if you have the right engine.
@@Zeek800thanks man, I'm finally running into this issue with my Cruze and like this guy I've already cleaned and replaced enough. Just gotta set apart a day for an intake manifold ig
Dam I didnt know the cruze 1.8l throttle bottle is electricity operated.
I figured since I dumped a whole can of seafoam 20oz and it went to limp mode
I cleaned the throttle body and maf sensor and disconnected battery to remove it from limp mode
It drives better than before and no check engine light or any stored codes.
Is there something I should check? Sensors or sum sort?? Since throttle body is electricity operated I feel like something is messed up lol
Help bro
Hi bud , if you don't have any codes showing your all good 👍
In the 'old days, with a lean condition, you would have to adjust the carburetor. Does the "lean condition" you dealt with the same as the lean condition we used to deal with? Also, the throttle body opening kind of looks like the mouth of a carburetor. If that is the case, can you also spray carburetor cleaner in there?
Carlos today its totally different. The carb is not at all like fuel injection .
@@SteveRobReviews I understand, but when speaking about a "lean" condition, are we talking about a "fuel" related condition?
Carlos in my experience sometimes its not fuel related at all , I've seen faulty sensors be responsible for reporting a lean condition but there was not a lean condition, this is where a good diagnosis is in order.
Just subscribed. I had the code too but the engine light went out. It's a Astra 1.6 2006 model. Been bitter cold and not been driving car that much. Went to start it and crank no start. I knew the battery was ok. But eventually had to charge the battery with trying to start anyway I took the air intake pipe off and cleaned MAF sensor took the pipe off and did the same with the throttle
Thanks 👍 nice to see your working on your vehicle.
You said no need of scan tool but actually you got the code P0171, it think it was important at first place.
You definitely need a scan tool for most diagnostic repairs but not all as some faults do not display a code. Cheers 👍
What could be the cause of a P0171 on a 2016 Jeep Patriot Latitude 2.0 we just replaced the MAP sensor but the vehicle still has a rough idle and the rpms run high while driving on the freeway approximately 65-70 mph the rpms are jumping up to 2200-2700 rpms. What could cause that? My husband already checked for vacuum leaks and says he can't find any obvious leaks. We just replaced the map sensor thinking that would fix it but it didn't so I'm thinking it could possibly be a bad Throttle Body w/Actuator IAC Idle Air Control or a TPS Position Sensor or even possibly a upstream 02 sensor. If anyone else can give me some advice on what I should fix next I would greatly appreciate it thank you!
Rhonda you definitely need a scan tool to look at codes and live data. It's best to test and not guess as I could think of $500 in possible parts so it's back to looking at data . Your lean code could be many things so start off with fixing that code first.
wait what side is not suppose to suck air the tube or the purge valve itself.
The side with the electrical connector is not the vacuum side but if the valve is stuck open its there you will notice a suction.
Hey man I have a 2014 and when I turn on the ac it starts idling bad the rpm gauge drops below 1 and it keeps going up and down sometimes even without it on and when it’s on high it dies any ideas?
I'd try the easiest resolve first and clean the throttle body .
can a upstream oxygen sensor cause the car to stall? Im having this issue but i already cleaned the throttle body. And changed the mad sensor. Changed the vacuum hose that goes from turbo to intake manifold.
There are so many things that can cause a stall . Looking at data always indicates something. You definitely need a scan tool.
@@SteveRobReviews would an oxygen sensor be one ? I have a small scan tool that shows live data for sensors. The upstream one stays under 0.200 and regulates. Up and down Starts at 1.025 or something like that. Then upstream drops rapidly to under .200
@@SteveRobReviews down stream stays at .800 and regulates up there in that range
I haven't seen an O2 sensor cause stalling. If it was out of range, you would have a check engine light on .
@@SteveRobReviews yea same
Here, I’m Getting p0171. System too lean. On a chevy cruz. I already changed maf sensor, cleaned throttle body, changed vacuum hose from turbo to intake manifold. Purge valve doesn’t look like its bad. Spark plugs and inside of exhaust is charcoal black. id assume its running rich
I got a sonic and have a diagnosis of a vacuum leak at the actuator under manifold. Any idea what part that is?
Nope , actuators are many so the diagnosis should have said what kind of actuator.
@@SteveRobReviews thanks. I'll try to get it out of them or pinpoint it myself now it is narrowed down. Any idea if those actuators are diy-able. They said it wasn't an easy job cause of the location. But who knows.
@pnnorton taking an intake off is not too bad of a job but getting to the intake bolts can be a challenge plus you need a torque wrench to tighten up. If your not real handy I'd let a tech do it.
What’s the name of that line that’s by the throttle body ?
I'm not sure of the exact name .
What was the cause of error P2096?
Lean codes are usually a symptom of a upstream fault. Post catalytic readings from a misfire .
What if a code does not pop up and you get a few seconds of rough idle?
It could be a couple of things, but I'd start at cleaning the throttle body .
@@SteveRobReviews Thank you
Check your spark plugs and coil pack, mine needed replacement at 55k
All u need is silicon
Ive done both of these things that your video shows and the issue hasnt gone away. My friend amhzs the same problem with his 2016 chevy cruze 1.4T limited LT. Ive tested the PCV valve, the purge valve both are good. Hes had the valve cover replaced, the MAF sensor replaced, both O2 sensors replaced, MAP sensor replaced, the plastic hose that runs on top to the turbo replaced, intake manifold replaced... i found this PCV fix kit online which is my last hope and also plan on replacing his timing chain being that the car is over 125k miles and its never been done before. He has a primary code P0171 as well as a few other secondary codes. If this PCV fix kit does not resolve his problem, do you have anymore suggestions?
Shaun there are mechanical failures to bad fuel injector to faulty fuel pressure. I'd look on the fuel delivery side .
@SteveRobReviews I checked the fuel pressure and the pressure is reading the correct psi, I plan on replacing the timing chain on the car since it is at 130k miles without being replaced and is louder on the intake side of the engine.
Did you find the issue? My car has the same issue and my mechanic said it was the 02 sensor but I replaced that already.
I have not found the issue yet. I have tried just about everything and anything. As of rn the check engine light is off to my knowledge. I used a difference kind of engine oil. I think the viscosity is incorrect for what they recommend.
The PCV system is to blame. That kit, if installed properly should fix the issue if everything else you stated was already replaced. The job takes at least 15 hours but 5hats because the JaB Weld part of the kit needs to properly cure ( 24 hours is even better ) the kit install should take a first timer 2 to 3 hours only because of salvaging the parts from the old system and some of the connectors are hard to pull off.
Spark plugs
Helped, but it wasn't a permanent fix for me
Sprayed it with what
Throttle body cleaner .
mas Airflow sensor use MAF Sensor cleaner. For the throttle body use Throttle body cleaner. Don’t spray the Throttle Body cleaner into the throttle body, use the method in this video or spray a micro fibre cloth and us3 your finger GENTLY. Locate where ant sensors or electric throttle plate actuator are are and don’t get any more than a lightly sprayed with cleaner cloth in that area. Do both the MAF and the TB, MAF sensor first, let it dry for 15-30 minutes before reinstalling and while you wait, clean the Throttle Body.
this must be a 1.8 engine because oil cap is not the same place then my 1.4
Yes your correct.
Steve I could use your help my 1.4 running rich up a hill going threw gass like crazy replaced throttle body already
No codes or no generic codes ? If its actually too rich it will throw a code . Does the check engine light work ? Lots of reasons for a engine running rich but I have never seen one that did not turn the check engine light on.
@@SteveRobReviews I have noticed a oil leak under my cat converter not sure if my tubro is leaking. There was oil in the throttle body when I replaced it with the new one better I couldn't get out of my driveway when I pressed the gas pedal. No.check in light on my dash at all my small scan tool doesn't show anything at all . I put converter cleaner in the gas tank I could smell egg smell before and carbon smell up a hill
Oil in the cat is not good. Your definitely looking in the right direction with the turbo.
Just wanted to verify...depressing the gas pedal without having the engine running doesn't make the fuel pump run, does it? Just don't want to do more harm than good to my vehicle if I do this (2014 Cruze LT 1.4T).
Hi Paul
Engine off - ignition off does not turn fuel pump on but engine off and just turning the ignition key in the start position does turn on the fuel pump on to prime the system. Depressing the gas pedal will not turn on the fuel pump .
Sounds good. Thanks for taking the time to respond to my question.@@SteveRobReviews
@@paulheiting6484 👍
When you push down the gas pedal your really just giving the car more air. The sensors itself work together with the ecu to tell the fuel pump it needs more fuel.
Giving it more air as in controlling the throttle body plate
