did chek engine light go off emidietly after you change gas cap? and on which car?

@@jaskosijaric4021 Kodiaq & no it didn't go off immediately. After a few cold starts.

Your welcome and glad the video helped! You're right, in most cars that's the situation. Thanks for the contribution and all the best to you! :-)

Did it just come on and stay on or did it come on flashing? Mine just happened tonight but I also thought after watching this video it’s could be my gas cap as well, since the other day I started my car and I smelled kind of strong gas and could not figure out why but did go get gas a couple days or a day prior.

@@rachelaimer6284 If the check engine light is flashing it definitely isn't the gas cap. That means it's something that needs immediate attention and you should stop driving. It could be you have a misfire if you smell gas. Misfires are when the spark plug in one or more of your cylinders isn't sparking to ignite the fuel/air mixture. This could be caused by a bad plug(s), a bad coil pack(s), clogged fuel injector(s) a bad signal from your ECM. The best thing to do is have it scanned. That will show you the error code that caused the check engine light to come on. Just remember, that only shows you where to start looking. You might pull a P0171 Fuel Trims are Lean. There are a few reasons why this could be. An 02 sensor might trigger it. You DO NOT want to just replace that sensor because there are other reasons that cause a GOOD sensor to send an error code. So many people do this. Then they reset the check engine light after replacing the part only to have it come back on in two days. Remember, it's just a code to let you know what to look at and narrow down the problem so you know you've got it. Vacuum leaks, a bad or dirty MAF sensor, tons of things can be off to trip that light. But...if it's flashing it's warning you that the problem is not good to keep driving. You could do permanent damage to you engine. You can buy a cheap scanner for about $20. More advanced ones run more. But a simple code reader is fairly cheap. I bought one for $20 that gives me the code and live engine data via Bluetooth to my Android. I can look at long and short term fuel trims, (very important on diagnosing how your car is running), misfire codes, 02 sensor readings, Catalytic converter temps. Remember, your cars ECM will make adjustments to things like fuel/air mixture to keep a 14.7/1 air to fuel ratio in your engine. So even though your car is running great you might still have a problem. You just don't know it yet because the sensors haven't hit the max to trip a code and have the check engine light turn on. If you notice your gas mileage has gotten terrible, you smell gas in the exhaust, these are signs that the ECM is making adjustments because something is off. The car will still run great but there's a problem. A vacuum leak after your Mass Air Flow Sensor is allowing un-monitored air into your intake throwing off that 14.7/1 air ratio your engine and ECM want. The ECM doesn't KNOW there's a vacuum leak. It just knows that there is more air than fuel. So, the ECM will send MORE GAS to your cylinders making your fuel trims go crazy. If they hit a max you'll get a P0171 code. Fuel Injection System Too Lean Bank 1 (or 2 if you have a V-6 or V-8). Most likely a loose vacuum hose, Dirty MAF Sensor or even a Dirty Air Cleaner. I know there is a lot of info here and you might not understand most of it. But a sensor code doesn't necessarily mean that sensor is bad. In fact most of the time it doesn't. So my point was to just save you money buying parts you DON'T NEED. You can email me if you have any questions. I'm happy to help anyone save money from rip off auto parts stores that WILL TELL YOU to buy this or that. They are WRONG 90% of the time. I hope this helps you. Feel free to ask any questions you have any.

@@RickyPisano Hi thank you! I do have one more and your response was actually very helpful and anything I didn’t know I just googled to find out so no biggie. When I started it up this morning the light did not appear. Could it be possible that it came on as warning? It is winter and there was a snow storm and I don’t think my grandfather pulled my car in his driveway after letting it warm up, I believe he just started it up and went to park it and then it shut off on him and he floored my gas pretty ruff to get it from the end of his driveway. I will still check as I had no time to do it in the mist of already having so much to do to add on to this. I’m hoping it was just a warning to not do that again or if not something very minor that can be fixed.

@@rachelaimer6284 If it went off and it's running OK then you should be fine. Keep an eye on your gas mileage and if the engine runs smooth. Like it normally does. If something is off the light will come on again. It may have been a very temporary low oil pressure signal because of the cold. That would be my guess by what you described. I wouldn't worry about it if the light went off on it's own. Something like a loose gas cap that triggers it will usually turn back off after a couple of cold starts once it's tightened. No biggie. I think you'll be fine. The newer engines post 2005 or so don't need to be warmed up. They have thinner, usually synthetic oil like 5W20 and when cold the ECU automatically runs the engine rich (open loop) until it's warm and hits operating temp and the O2 sensors kick in (Closed Loop). Then the air/fuel mixture is automatically adjusted by those readings. The old carbonated V-8's, Slant/straight 6's and 4 cylinders had way thicker oil like 10W40 and it would get like molasses in very cold weather and had to be warmed up to pump through the engine effectively. The Choke on the old carburetors would be open to make the engine idle higher on those engines and you actually had a "gas pedal". On these newer ECM controlled engines you don't. The pedal you press is actually an "air pedal" that opens and closes the flap on the Throttle body to allow more or less AIR into the engine as the ECM is in full control of your fuel that enters the engine based on the amount of air entering it at different speeds and RPMs. The air coming in is measured by the Mass Air Flow Sensor or MAF positioned in front of the throttle body to maintain that 14.7/1 air to fuel ratio. I still let my 2005 V-6 warm up a bit though before I put it in gear and take off. I still think it's a good idea to do that when it's really cold out to make sure oil pressure is ok and no warning lights stay on. I think you'll be fine though as long as the light is off and the engine is running like it normally does. I hope this helps you.

Hi David and thanks for watching! You're right the present system has a lot of flaws and is sometimes unreliable, even to the point that some good old thinking and old-school problem-solving does a better job. Perhaps someday a car will have some sort of its own self-diagnostic system which will give more precise information. All the best to you!

It’s not that they can’t make a sensor that tells you, they don’t want to. They want you to have to take it to an authorised dealer. ££

try FIXD

They don’t have a censor that tell you what’s wrong because there’s no money on that if you know the problem then they won’t b able to charge u 500 dollars to tell you there’s something wrong and if u wanna know what it is it’s another 300 dollars and if u wanna fix it then it’s half the cars actuall price

but did they send a man to the moon think about it

lmao what??? 😂

Be careful. Or roll a doobie instead.🙂

love this

Disconnect car battery for few minutes and connect. Might be that computer need reset.

Yes because the light does not turn off immediately

Hi and thanks for watching! Yes, when the check engine light comes up there may be an increase in fuel consumption, all depending on the fault. That engine is known to have a higher fuel consumption, at least from what I've seen.

@@UltraxHere straight away as far as I remember

You're welcome and thanks for watching!

Hi Glyn and thanks for watching! With modern cars, there's always a good possibility of a money pit. You just can't know. What I would do if I was in your place is to check all the connections to the sensor. I would check for good contact and that the tubes aren't clogged, just in case. If that was OK, I would replace the sensor, erase the fault code, and see what happens. This is all the advice I can offer and I presume that you came to the same conclusion. But this seems to be the only path to at least start and solve the problem. Hope this helps at least a little bit. Best regards!

Oh and more thing just from the top of my head: check that the exhaust isn't punctured or burnt out anywhere.

Hi Mikael and thank you for watching! To be honest, I wouldn't say that water is causing the problem. If so, the problems would be more dramatic. If there's isn't any previous damage done, then the water shouldn't be able to reach the air intake at all. I don't know what type of engine you have, but I'd rather check the whole air intake system for any air leaks (of course the air filter also). Besides this, I would check the throttle body or the PCV valve, just in case. If you have an OBD scanner, making a scan would also be good. Fabia's are known to act up for these reasons, especially the earlier models. Hope this helps and best regards!

@@DespairRepair I did an OBD scan, and I got two codes of malfunction. One is "Cylinder 3 - misfire detected" and the second is "Heated oxygen sensor (HO2S) 2, bank 1 - circuit malfunction". I also noticed that in the car grill, there is a hole right in front of the engine air intake. This hole is completely open (no bars, nothing), and it looks like the edges are torn, like if there has been some sort of protection there before. So perhaps to much rain and water passes through that hole and causing some electrical hiccups with the oxygen sensor?

@@MikaelWallSweden well it might be but I haven't heard of that kind of problem. Anyway, what type of engine do you have? Is it the three-cylinder engine?

@@DespairRepair It's a four cylinder! 2001, 75hp

​@@MikaelWallSweden if I was in your place, I would first solve the misfire problem (perhaps try checking the ignition coils). A misfire may easily cause the O2 sensor error thus triggering the check engine light. This is a wild guess and hope it helps.

Hi and thanks for watching! If you're talking about the temperature sensor, yes it will, it's a common fault on VW group cars of that era. We're making a video soon just about that.

Hi Tim thanks for the kind words and for watching! You've checked more or less everything. I would check once more for an air leak (like punctured hoses, loose clamps, or else). Sorry for the late reply and hope this helps.

Thank you for the nice comment and for watching :-)

You're welcome and thanks for watching!

You're welcome and thanks for watching!

what was your car doing .to make u change gas cap?

Disconnect the negative connection from the battery for a minute.

Hi, and thanks for watching! If we're thinking about the same thing, it's the Onboard Diagnostic reader, aka OBD reader

Hi Dominga and thanks for watching! Yes, you can try to do that. When you take off the battery terminal, also press the horn to discharge the system totally. Keep the door or window open just in case, so you have access to the passenger cabin. If this doesn't work, then using an OBD tool is the next best thing. Hope this helps. Don't know why it showed up after the battery replacement, it shouldn't be that way. .

Hi, well if I understood right, you just cleaned the sensor and didn't replace it. Cleaning, at least from my own experience has success to some point. The usual outcome is to replace the part if you want the repair to last. The code is for a faulty MAF sensor but there could be other problems triggering that code. I would recommend starting with cheaper and more simple things and then replacing more expensive parts. Check for air leaks also. Btw, what car is it and with what engine?

Thank you and glad if the video helped 🙂

Hi Karl and thanks for watching! This probably won't help much but, if I understood well, the cold air intake is installed as an aftermarket part. If so, did you try returning the original parts of the air intake and see will the error code appear again? As you probably know, this error code comes from a vacuum leak, near the intake manifold, defective sensor, faulty gasket, and else. Did you check that everything is tightened and in place? All modern cars are highly dependant on precise and predefined airflow and if it's not like that, all kinds of problems appear. Best regards

Thank you for watching!

Did you get help, I have the same problem. I keep on disconnecting battery now and then to put off the check engine light. Am tired of disconnecting battery

Hi and thanks for watching! To be honest, it's hard to say with this information but it probably loses power since it goes into limp mode when the check engine light goes on. Regarding the sound, I would first check if everything on the air intake is OK and properly set and tightened. Especially do this if there was recent maintenance done. Hyundai is a good and well-built car and I doubt that something serious is wrong. Hope this helps.

Thanks for watching and for the nice comment!

Hi and thanks for watching! To be honest, if there's no immediate sign of danger, you can drive for hundreds of kilometers (this is from personal experience). But nevertheless, hook up an OBD tool as soon as you can and get the error code. It's sometimes just a glitch in the system and sometimes it's more serious. Hope this helps.

@@DespairRepair hi and thanks for the reply. I sent the car to my mechanic, since I have a long journey planned and I didn’t want to take any risks, and fortunately the issue was minor, just a problem with the glow plug. He said that I shouldn’t have to worry about that, and I could change them later also, but before winter. Thank you again, and all the best.
