Hey Now Tampa Tec... Great video and information about this technology. I really appreciate it I'm a tech who also lives in Tampa (via Philadelphia) Good job my friend, Matty.
+I Am The SONOFOVERBROOK thanks, I tried to fix some parts few people were upset about but can't edit this video, so I made a better version "4 WAYS TO RESET CHECK ENGINE LIGHT" goo.gl/xsfnoJ
Just wanted to thank you. This saved my ass. My Mitsubishi Endeavor's light would not turn off. The dealer charged me $110 just for the privilege of speaking to them about it, where they proceeded to hand me a bill for over $3000 in repairs, insisting I would not pass an emissions test without all of it. I yanked the negative on the battery for a couple minutes, plugged it back in, completed the drive cycle (about 40 mi. of city and highway driving), and the light never came back on. Passed emissions without a single error. Thank you, thank you!

You are a Godsend, my first day for college and my engine light goes on. I'm a single lady and am broke at this time. I LOVE RUclips for all the helpful videos and yours showed me that my gas cap was barely on. Hope that is the fix. Thank You again for saving my mind. Brenda
what 's up with all the negative comments, this video was just explaining how to reset the light, not fix any problems. so STFU ! I came here to find out about reset and I am happy for this video!!!!!!!! thanks for the video!
Why is everyone so negitive? He is only trying to help! I thank him for his insight and his time for making the video. It may not work for long but it will pass inspection.
nope,!!! it won't and it will turn back on between 2 to 5 miles. and one last thing you don't have to wait 5 minutes for the computer to reset. once you disconnect the cable it resets QUICKLY.
Was about to take my Mazda 5 into the dealership, would have cost 115 just to look at it. I already knew that the gas cap had been left off, but the engine light wasn't re-setting after it was screwed on properly. Your video just saved me the time, trip, and expense. Well done and thanks!
Thank you for your video, I never thought the gas cap could be the reason why my check light was on, but couple days ago I went to the gas station to fill up the tank, then close the cap and realized couple blocks away that the light went off. I almost spent a lot of money buying the converter and sensors online. Thank you for sharing this video!
OMG!!!! you are not going to believe this but, my light had been on for over a year and I'd taken it to many mechanics and it seemed like no one knew how to get the light to go off. They took out this scanner and did some reading and I had things replaced that I was told that needed replacing. Afterwards the light went off to only come back on after driving a couple of miles. I'm not saying the light will not come back on but they did not know something so simple would make it go off. If it stays off I will come back and repost and let everyone know. Not that is probably matters but...Tampatec, thank you for posting this to youtube. I am subscribing to your channel for sure. Thank you. Now I got to get her smoged and serviced. She need it so badly.
My husband will do what you said in your video. I'll post the results. We have a Honda Civic 2004 and the engine light is on since about 10 months ago. Everything seems to ok, but the light is still on. Thank you for sharing.
You are the best man! thanks a lot it worked for me I borrowed my girl friend's car and engine check sign came up, she would have killed me if I had messed up with the engine, you saved my ass! thanks again
This is so good to know. I was about to take my 2002 Ford Taurus to the garage before I saw this video. I have never replaced the original gas cap, so I'm definitely going to head to Amazon first, and then I will do the ground battery routine. I love the internet. I save so much money this way.
FIX THE PROBLEM FIRST. Resetting the C/E light is done only AFTER the problem that caused the C/E is fixed. If you don't fix the problem that caused your C/E light to come on and reset the light, the light will come back on.
OHHHH MYYYY this video..... is.... by far...... the most entertaining thing I have ever seen on youtube . I watched this video 20 minutes ago ...and I am still laughing.the content of this video....lolthe amount of plays it actually has...LOLthat people on here have actually taken his advice, tried it out... and came back and commented ..hahaha
WOOOOWWWW!!!!!! you tube have only genius people!!! damn if it was that easy, why there is mechanics at all? and the highly sophisticated tool that was use, is that a NASA Approved sonic screwdriver? but seriously, i got rid of my check engine light by just taking out the light bulb and voila!!! did not have to disconnect any battery......
Thanks alot.....i knew that ............BUT I FORGOT......For that great video..i owe you ..thanks..take my advice.............don't get OLD like me..i just realized that i am going to start a car repair guide book of things i fixed so i can do it the next time.....i appreciate your help
I have a mustang with a "no cap" gas tank. It's a few years old with a little over 11,000 miles. It gives me so much trouble between trying to fill it up. Today my check engine light came on. Although I should have gone to autozone and get a reading... It worked. So far after a good drive not on again.
+HisDukeNess Fords do collect debris in the cupped area right below the filler hole, also teh seal around the cover sometimes splits or leaks, the door spring gets weak etc.
Thank you so much! I was gonna take car to mechanic for check engine light 99 honda civic. Watched your video, gas cap wasn't on tight, reset as per your instruction.
I want to thank you so very much, Yesterday I changed my filter in the car and I drove about 20 miles on my way back home my engine light came on, but I just changed the sensor in march. I will put back the old filter and try your way. Thanks a million.
As long as the problem is there the CL light will come on again. It looks like your problem is a fairly common one easy to pin point and solve. One good advise is never to tighten the gas cap in a rapid way. I spent a lot of money on 02 Santa Fe until I realized and then learned to close the cap slowly and not more than three ticks. This may work for some as well.
'99 Chevy Tahoe here. Got the light and used the free meter at O'Reillys. The interpretation I got from an old boy at the counter was that a vacuum leak is usually a failed gas cap. Put the new cap on and the light went right out. Another unrelated problem I had where I did the battery trick.. and the light came back on in less than half a minute.
I have a Mazda Mx5 nd if you remove the battery it needs the tyre pressure sensor resetting the tracker alarm recalibrating and a couple of other items it's easier to just do the clutch brake sequence to reset the E Management warning light as long as you know what the reason for it is. However this was a useful bit of info for those who cannot locate the reset sequence on line.
Wicked, worked a treat, I had run for a while without the temp sensor so it threw up the engine management light, I then had a new starter put on it (which is why the wire was disconnected because it worked with the lead off (management system thinks cars cold so heats the plugs so a worn starter will start the car). Anyway all sorted now, thanks.
Thank you soon much for this video!!! Just tried it and IT WORKED!!!!!! My husband pumped my gas the other day with the engine running which we never do and it keep reading my gas cap.
That's the same thing as doing a "hard reboot" on your laptop, smartphone, or tablet (unplug from the charger, remove the battery, wait 30 seconds, reinstall the battery, and turn it on). In many cases, this will also wipe out some rather nasty viruses.
+Asz Fantom Fixed nothing, just force it to go into emissions readiness testing mode again, this thread is just a never ending circle for the misguided.
Got MADZA MPV 2002, Change all the brake , Disk, pad, now ABS sometime stay on, and recently BRAKE LIGHT, I suspect Problem with bushings, bering seem ok what do you think ?
Thanks for sharing. Here are a couple things that might help you n the future: 1. If you are going to suggest to viewers that they buy a tool kit, I would suggest that they buy a wrench to remove the battery terminal instead of locking pliers. Using anything other than a wrench or socket will damage the nut, making it harder to tighten and loosen the next time. 2. The only part of the gas cap that matters is the seal around the top. Yours looked fine. As long as the cap locks down tight against the top of the filler tube, and the seal isn't cracked/damaged, its fine. 3. It can take up to 100 miles of driving after a "battery reset" to throw the same error codes. This isn't a fix, it just turns the check engine light off. The problem that turned the light on is still there, and will not go away by turning the light off. Think of this as removing the bulb behind the check engine light icon in your dash. The light isn't on, but the problem is. Take care, and good luck with your van.
I work at a place that installs batteries. While it is true that on some vehicles you can disconnect the battery and nothing will happen except losing your radio presets, many vehicles, especially newer ones, require an OBDII memory saver to be used, otherwise your cars computer can lock up, or at the least, your radio will lock up (especially Hondas) and you will need a code from the dealer to unlock it.
John Eshelman Exactly WRONG ! That would make the ANTI-THEFT CODE available to radio thieves and defeat the whole reason for it's creation in the first place !
dont expect to reset your check eng. light and then pass the state inspection. I am a state inspector for mass. If you reset the check engine your vehicle will not have the monitors ready (o2 sensor, cat, emissions, ect.) so good luck. also this wont damage your car but like some people have said. it will reset everything and unless you know how to program your sunroof, power mirrors and sometimes radio you may have to take it to the dealer for a little bit of money.
Hmmmm...looks like a good tip. Will try tomorrow. The light just came on in my car tonight. Had not driven it for about 2 and a half months. And just changed to a new battery too. Hopefully it's just the electronics messing around and nothing serious
i have a eclipse gt 07 and i was told oxygen sensor but im gonna check my cap i don't never here that click in sound just thought about it. i got a new battery and the engine light came back on after i got that hooked up. thanks ill check the cap
I worked in emissions repair for years until recently when I started at the University...locking gas caps are notorious for leaking. A standard gas cap with a good soft rubber seal is perfect. Now, idiots at auto zone saying there was "air in the tank" needs to be fired. There's ALWAYS air in the tank. When the system doesn't pressurize properly, due to a leak, the computer sees there isn't enough flow coming into the carbon canister and throws this light. Most times it's a gas cap, but the code reads a leak SOMEWHERE in the system. Now, you may have reset the MIL and set all of the emissions "readiness indicators" to "Not Ready", but when the drive cycle is completed, the light may come back on. Until the system hits proper conditions to test the pressure of the fuel storage system, the light stays out, but the "readiness indicator" for that particular system is not set as "ready". If too many (more than 3 in AZ) are not yet "ready", you are told to look up and drive the "drive cycle" for your vehicle.
I unhooked my battery cable then hooked it back up and the engine light turned off. Then I went to get my inspection and they hooked it up to an "EVAP" machine and it detected that the engine light was on. How can I get past this issue? YOU MENTIONED THAT REMOVING THE FUSE AND PUTTING IT BACK RESET THE COMPUTER, WILL THAT HELP BYPASS THE "EVAP" DEVICE? I live in North Carolina and they are real strict about inspection. "I DRIVE A '96 Mercury Sable"
Any thoughts on how to reset the ABS brake warning light on my 2005 Ford Escape Ltd? Just changed my brake pads and now it comes on every time I drive.....Thx
Ya if the ABS light is on you may have damaged an ABS sensor. ^ Also as above if you didn't plug it back in properly it will do that as well. Keep in mind if that light is on, it automatically disables ABS functionality.
So basically i should buy a big ass toolkit on ebay but still use a Tool that is not at all made for the task. Thank you for THAT brilliant piece of advice.
So I filled up my tank the other day was in a rush and forgot to screw the gas cap back on turned on the car didn't pull out the gas station yet though, then someone came over and told me I left my cap off, but the next day the service engine soon light came on (not blinking though) I have a 01 pathfinder do you think the battery reset trick will still work? Well for any car/truck make or model? I do intend to go to auto zone for a code reading too. I am no novice but I like the idea of diy and saving money.
you don't need to do anything the check engine light is gonna reset by itself(it takes time) like mine did the next day after I fixed the problem which was loose gas cap, unless there is another problem!
I have watched several videos on fixing the engine light-on problem for Toyota 2003 Corolla for I have had the problem for many years. This time I changed my mechanic to Shell service station, Bellerose, NY 11001. He tested the engine with the diagoniser, and changed the top mount gasket, and that immediately solved the p0171 and p0770 problem. The engine light-on has been off since then. You may want to try this solution.
I have a 2006 F250 6.0L diesel and I get a wrench light on dash. If I turn off the truck the light goes away. Later it comes back on. Most of the time it is when I have cruse on. Do you know of a fix or what causes this. When I hook up diagnostic tester it show everything fine and no error codes.
Hint...when working around a battery...take off your rings....Last thing you need to do is touch the pole on the battery and have your ring hit the side of the body....there goes your finger....burned to a crisp. Use caution.
Thanks for your efforts and your attempt to be helpful. I would like to repeat the caution noted by several others that you should always use a wrench of the proper size when removing a nut. If I see a mechanic who is working on my car attempt to use pliers or channel locks to remove a nut, I ask him to use the proper wrench. I would not return to his shop. My thinking is that if he's slipshod about using the correct tool, he is likely to be slipshod on other issues.
Will give this a try. A few days ago I was stopped at a light and the car started to idle rough then the check engine flashed on and off several times then stayed on solid (97 lexus). I pulled over and stopped the car. Checked under hood for anything obvious. Restarted the car and it is smooth as can be but the light is still on.
The rough idling is called a misfire. you would have codes ranging from P0300-P0308 or potentially P0200-P0208. It was flashing because the misfire was great enough or on enough cylinders to do catalytic converter damage due to the amount of unburned gas getting into the exhaust. Unless other lights came on as well.
Most people who turn the CEL off simply to make it go away will just end up screwing this up horribly. They'll either disconnect the positive terminal and short it against the body, strip the nut using the wrong tool like you did, and in some cases probably not even find the battery depending on manufacturer. Not to mention if they don't have their radio code, the alarm system resets, etc. More trouble than it is worth. Idk why you didn't just have autozone clear the code for you if that's all you wanted. Or better yet just stick a piece of tape over the light if you're not interested in diagnosing the real problem.
Whilst I agree with most you have said, re, not getting to the root cause of the problem I fail to see how a disconnected positive wire could short against the body, once it is disconnected there is no circuit.
And he breaks out the Vise grips wow what a PROFESSIONAL I want hims to teaches me how to fix them things and trucks too Ohboy I will be the bestest mechanical guy anywheres yuppers MUHAHAHAHAHAHAHAHA
+An Ordinary Do ::: you are so correct with your comment this is DIY and I HAVE had mechanics PROFESSIONAL MECHANICS Tell me to do the same thing after they have ran all the diagnostic test and found nothing wrong with the car other then this light was defective and it would cost way more to replace the light then was needed some people just look for reasons to belittle and complain. they have nothing better to do !
Lynn Reedy I dont know if I should be taking your word. Please understand as there are a lot of one legged astronaut PhD Emperor Ambassadors on the internet.
have you no sockets or spanners to take off that battery lead,did the light come back after you replaced the cap?You know you just reset the whole system.
Tung Quach Most times false engine lights ,airbag lights etc.: are all caused by faulty batteries.. replace your battery with a good quality battery and your trouble's will disappear.
+Alexander Bertt Most times? False. Most systems work at a low enough voltage that battery drain does not effect it, as it will with a Mercedes, BMW, Volvo or VW for example. As for the passenger airbag, there are plenty of reasons, including faulty connectors as mentioned or the seat sensor pad, which are far more common than a low battery. MOST are ALL caused? nope.
You don't have to wait for 2mins or so to reset the ECM (Engine Control Module). All you need to do is remove the negative terminal of the battery (you can use your hand don't worry, 12v will never fry you) then short circuit the NEGATIVE CABLE to the positive terminal of the battery using any conductor or cable. In this case, all capacitor will be discharged. NOTE: Removing the battery terminal will reset your radio, if your radio is coded, then you have to make sure that you have that code. Otherwise, dealer will make a fortune from you. Also, don't use tools like he used, that will worn out your terminals.
hi please i have aqustion..i have ford galaxy 2.0 diesel 2009..last week the temperature gage goes high till 110 while I am in traffic jam i stopped immediately the engine a little bit warm but fan doesn't work? after i use the car without any problem till now i drive for long distance no problem. I don't know this happened shall i check the car ?
Hi today I went to a car wash today and I got the place to clean my engine bay when they power washed it and after I went thru the car wash after I came out my gas tank lid was full open would the fan blow air into the cap or something now I still have the engine light on -_-" & my exhaust now is making a popping sound would you know what it means? 2004 Mazda tribute ES V6
170324341a Here on the front range in Colorado (9 county area) if they even see a check light on you'll never make it to testing, and no charge either.
Hi guy, this works of course. My Mazda 6 check engine light came on at 30,000 miles and I sprayed the Mass Airflow Sensor (MAF) down with some MAF cleaner and then reset by disconnecting the battery terminal. Engine light never came back. Just FYI.
+Robbie JK Resetting the light didn't fix it though. It would have gone out in a couple of drive cycles if it was just a dirty MAF. All this does is delay your ability to pass an emissions test until it triggers again and you fail anyway. In your case, you had a problem that cleaning the MAF helped alleviate. My tester has several thousand test parameters, depending on vehicle complexity, there are a LOT of things that trigger a CEL besides a MAF, in fact the MAF is a rare one these days. Being a former Ford tech (Ford is the same as Mazda for most of the engines and drive trains...AND chassis!) I clean my MAF every 6 mos anyway, it's a Ford/Mazda thing, they work forever but do need periodic cleaning.
+Delanie Epps Might do, but only IF you have a dirty MAF that is triggering a code or dirty enough that something else triggers a code easier than normal. Be aware though that there are a few thousand codes and even more reasons they trigger.
Good technique. Most cars today needs a scan tool to trouble shoot the check engine light and to reset it. The negative battery technique don't work for them. Regards,
Evaporation leak codes can be anything from faulty gas cap to vacuum hose in engine compartment after repairs if you are doing the job your self and taking the ground does not reset the light take positive off and turn ignition to accessories or run. live it like that for a minute or two light should go off

That's the same thing as doing a "hard reboot" on your laptop, smartphone, or tablet (unplug from the charger, remove the battery, wait 30 seconds, reinstall the battery, and turn it on). In many cases, this will also wipe out some rather nasty viruses.
Disconnect battery for 5 minutes,and job done.i did twice,easy.
+Asz Fantom Fixed nothing, just force it to go into emissions readiness testing mode again, this thread is just a never ending circle for the misguided.
A happy wife is a broke Hubby..
😆 I just saw this years later but hope my wife doesn't.
You fix androids! Excellent ! Because Motorola Cant. That gas cap is WOW, did it fall off on the highway?
"Happy Wife is a Happy Life" - you made me SMILE and I LIKED. Thank you
Got MADZA MPV 2002, Change all the brake , Disk, pad, now ABS sometime stay on, and recently BRAKE LIGHT, I suspect Problem with bushings, bering seem ok what do you think ?
Thanks for sharing. Here are a couple things that might help you n the future:
1. If you are going to suggest to viewers that they buy a tool kit, I would suggest that they buy a wrench to remove the battery terminal instead of locking pliers. Using anything other than a wrench or socket will damage the nut, making it harder to tighten and loosen the next time.
2. The only part of the gas cap that matters is the seal around the top. Yours looked fine. As long as the cap locks down tight against the top of the filler tube, and the seal isn't cracked/damaged, its fine.
3. It can take up to 100 miles of driving after a "battery reset" to throw the same error codes. This isn't a fix, it just turns the check engine light off. The problem that turned the light on is still there, and will not go away by turning the light off. Think of this as removing the bulb behind the check engine light icon in your dash. The light isn't on, but the problem is.
Take care, and good luck with your van.
I work at a place that installs batteries. While it is true that on some vehicles you can disconnect the battery and nothing will happen except losing your radio presets, many vehicles, especially newer ones, require an OBDII memory saver to be used, otherwise your cars computer can lock up, or at the least, your radio will lock up (especially Hondas) and you will need a code from the dealer to unlock it.
a Honda radio code is located in the glove box.
Drew Proulx If you're lucky... People take them out for whatever reason. They should be stuck on the side of the glovebox instead of being removable.
John Eshelman Exactly WRONG !
That would make the ANTI-THEFT CODE available to radio thieves and defeat the whole reason for it's creation in the first place !
Drew Proulx thus defeating the the whole reason it was created. Morons..you probably have your spare house keys in there as well !
dont expect to reset your check eng. light and then pass the state inspection. I am a state inspector for mass. If you reset the check engine your vehicle will not have the monitors ready (o2 sensor, cat, emissions, ect.) so good luck. also this wont damage your car but like some people have said. it will reset everything and unless you know how to program your sunroof, power mirrors and sometimes radio you may have to take it to the dealer for a little bit of money.
Well thank you for this video. This was driving me nuts on my 2013 Impala LTZ. Works as advertised.
wowwww what a genius,,, 24 hours later the light will be back on...
+ocimar lacerda right
hahaha 20 miles later!!! lol
is this demonstration for a Pontiac G6 Gt because I'm having problems with the few lights that are on in my car but the car runs fine
Hmmmm...looks like a good tip. Will try tomorrow. The light just came on in my car tonight.
Had not driven it for about 2 and a half months. And just changed to a new battery too. Hopefully it's just the electronics messing around and nothing serious
i have a eclipse gt 07 and i was told oxygen sensor but im gonna check my cap i don't never here that click in sound just thought about it. i got a new battery and the engine light came back on after i got that hooked up. thanks ill check the cap
Not trying to nitpick but using vice grips to turn that clamp bolt could result in rounding the nut. Better to use an open end wrench.
You are so right. He needs invest a few dollars and get a set of combination wrenches. Otherwise it's a good video
I worked in emissions repair for years until recently when I started at the University...locking gas caps are notorious for leaking. A standard gas cap with a good soft rubber seal is perfect. Now, idiots at auto zone saying there was "air in the tank" needs to be fired. There's ALWAYS air in the tank. When the system doesn't pressurize properly, due to a leak, the computer sees there isn't enough flow coming into the carbon canister and throws this light. Most times it's a gas cap, but the code reads a leak SOMEWHERE in the system. Now, you may have reset the MIL and set all of the emissions "readiness indicators" to "Not Ready", but when the drive cycle is completed, the light may come back on. Until the system hits proper conditions to test the pressure of the fuel storage system, the light stays out, but the "readiness indicator" for that particular system is not set as "ready". If too many (more than 3 in AZ) are not yet "ready", you are told to look up and drive the "drive cycle" for your vehicle.
+Jason Nichols good to know thanks, very smart comment and informative.
I unhooked my battery cable then hooked it back up and the engine light turned off. Then I went to get my inspection and they hooked it up to an "EVAP" machine and it detected that the engine light was on. How can I get past this issue? YOU MENTIONED THAT REMOVING THE FUSE AND PUTTING IT BACK RESET THE COMPUTER, WILL THAT HELP BYPASS THE "EVAP" DEVICE? I live in North Carolina and they are real strict about inspection. "I DRIVE A '96 Mercury Sable"
It worked. Thanks
You saved my money
A happy wife is a happy life..Love that..
Any thoughts on how to reset the ABS brake warning light on my 2005 Ford Escape Ltd? Just changed my brake pads and now it comes on every time I drive.....Thx
i took my car to local ford dealer and they reset it for free but depends where you go.
did you plug in your ABS sensor? perhaps thats why the light is on
Ya if the ABS light is on you may have damaged an ABS sensor. ^ Also as above if you didn't plug it back in properly it will do that as well.
Keep in mind if that light is on, it automatically disables ABS functionality.
So basically i should buy a big ass toolkit on ebay but still use a Tool that is not at all made for the task.
Thank you for THAT brilliant piece of advice.
it worked! gas cap was not close properly by the gasboy...lol
Good. Always use the right tools for the job. In this case a wrench otherwise eventually you'll mess up the nut on the battery clamp.
So I filled up my tank the other day was in a rush and forgot to screw the gas cap back on turned on the car didn't pull out the gas station yet though, then someone came over and told me I left my cap off, but the next day the service engine soon light came on (not blinking though) I have a 01 pathfinder do you think the battery reset trick will still work? Well for any car/truck make or model?
I do intend to go to auto zone for a code reading too. I am no novice but I like the idea of diy and saving money.
Your light is back on?
Jak StG Yes you BET it's back on... This does Nothing to repair this problem...
I know that does nothing to fix the problem. I'm no dummy when it comes to cars. I was simply referring to a prior conversation we had about this.
Auto Zone can put the light out for you unless it's a VW.
you don't need to do anything the check engine light is gonna reset by itself(it takes time) like mine did the next day after I fixed the problem which was loose gas cap, unless there is another problem!
I have watched several videos on fixing the engine light-on problem for
Toyota 2003 Corolla for I have had the problem for many years. This time
I changed my mechanic to Shell service station, Bellerose, NY 11001. He
tested the engine with the diagoniser, and changed the top mount
gasket, and that immediately solved the p0171 and p0770 problem. The
engine light-on has been off since then. You may want to try this
solution.
Also, remove the positive connection from the battery and hold it to the negative post for 30 seconds or so.
I tryed to do this but i couldn't do it for 30 seconds it was just really painful .. am i doing something wrong???
This worked for me...went to refill gas and the attendant never replaced cap well ..Thanks Tampatec
Thank you. I forgot to ask my husband before he went to work, & its time to do an inspection. :-)
I have a 2006 F250 6.0L diesel and I get a wrench light on dash. If I turn off the truck the light goes away. Later it comes back on. Most of the time it is when I have cruse on. Do you know of a fix or what causes this. When I hook up diagnostic tester it show everything fine and no error codes.
Hint...when working around a battery...take off your rings....Last thing you need to do is touch the pole on the battery and have your ring hit the side of the body....there goes your finger....burned to a crisp. Use caution.
The cap seals on the brown rubber gasket inside . Yours is fine. The thread are a little rough, but serviceable.
Thanks for your efforts and your attempt to be helpful. I would like to repeat the caution noted by several others that you should always use a wrench of the proper size when removing a nut. If I see a mechanic who is working on my car attempt to use pliers or channel locks to remove a nut, I ask him to use the proper wrench. I would not return to his shop. My thinking is that if he's slipshod about using the correct tool, he is likely to be slipshod on other issues.
Will give this a try. A few days ago I was stopped at a light and the car started to idle rough then the check engine flashed on and off several times then stayed on solid (97 lexus). I pulled over and stopped the car. Checked under hood for anything obvious. Restarted the car and it is smooth as can be but the light is still on.
The rough idling is called a misfire. you would have codes ranging from P0300-P0308 or potentially P0200-P0208. It was flashing because the misfire was great enough or on enough cylinders to do catalytic converter damage due to the amount of unburned gas getting into the exhaust.
Unless other lights came on as well.
thank u i had the same problem and i am very happy i fix it .
Great thanks a gas cap was bad toyota dealer not have to change my car thanks.
What we have learned to today:
Tools can be used in a strange way. OMG :D
nothing like useing the right tool for the right job ha? vise grips to loosen a nut,,,, very professional
South West Florida Aerial
It worked!!!Thanks a lot man !!!!
Thanks man i had the same problem and it work
Most people who turn the CEL off simply to make it go away will just end up screwing this up horribly. They'll either disconnect the positive terminal and short it against the body, strip the nut using the wrong tool like you did, and in some cases probably not even find the battery depending on manufacturer. Not to mention if they don't have their radio code, the alarm system resets, etc. More trouble than it is worth. Idk why you didn't just have autozone clear the code for you if that's all you wanted. Or better yet just stick a piece of tape over the light if you're not interested in diagnosing the real problem.
Autozone will read codes for free but they are not allowed to clear codes. They won't do it.
Whilst I agree with most you have said, re, not getting to the root cause of the problem I fail to see how a disconnected positive wire could short against the body, once it is disconnected there is no circuit.
Thomas Barrett What if your tool touches the ground WHILE the battery cable is being disconnected?
Stantonv Does not matter if the Negative is disconnected first.
David Phillips
Just be very careful not to ground out the positive while disconnecting the battery. It could explode.
will it clear abs warning light as well?please tell me i have mazda 2002 portege its abs and parking lights r on:(
Take your vehicle to Auto Zone they will clear it for your for free!
right!
Dmitriy Bildeiko will they do it on a 91 celica? or it has to be 96+ for obd2
THANK GOD WORKED ON 2005 RENAULT MEGANE 1.9DCI :)
And he breaks out the Vise grips wow what a PROFESSIONAL I want hims to teaches me how to fix them things and trucks too Ohboy I will be the bestest mechanical guy anywheres yuppers MUHAHAHAHAHAHAHAHA
He never said any of that. This is just a diy video. Why are you here if you are just heckling?
+An Ordinary Dog It's misleading bullshit. People here have been mislead already and it delays their ability to pass a smog test.
+An Ordinary Do ::: you are so correct with your comment this is DIY and I HAVE had mechanics PROFESSIONAL MECHANICS Tell me to do the same thing after they have ran all the diagnostic test and found nothing wrong with the car other then this light was defective and it would cost way more to replace the light then was needed some people just look for reasons to belittle and complain. they have nothing better to do !
Lynn Reedy I dont know if I should be taking your word. Please understand as there are a lot of one legged astronaut PhD Emperor Ambassadors on the internet.
have you no sockets or spanners to take off that battery lead,did the light come back after you replaced the cap?You know you just reset the whole system.
cool video man ....what about the passenger airbag yellow light?
Tung Quach Check the conectors under the passenger seat.
Tung Quach Most times false engine lights ,airbag lights etc.: are all caused by faulty batteries.. replace your battery with a good quality battery and your trouble's will disappear.
+Alexander Bertt Most times? False.
Most systems work at a low enough voltage that battery drain does not effect it, as it will with a Mercedes, BMW, Volvo or VW for example. As for the passenger airbag, there are plenty of reasons, including faulty connectors as mentioned or the seat sensor pad, which are far more common than a low battery.
MOST are ALL caused? nope.
+ozmedia i was just about to post that wont work on Mercedes and bmw lol
Charlie Hutch
Actually, in many cars it's true, but its far from the standard.
Hey Tampatec,
You reckon this will work on a Clio to deactivate the immobiliser?
Many thanks in advance
You don't have to wait for 2mins or so to reset the ECM (Engine Control Module). All you need to do is remove the negative terminal of the battery (you can use your hand don't worry, 12v will never fry you) then short circuit the NEGATIVE CABLE to the positive terminal of the battery using any conductor or cable. In this case, all capacitor will be discharged.
NOTE: Removing the battery terminal will reset your radio, if your radio is coded, then you have to make sure that you have that code. Otherwise, dealer will make a fortune from you. Also, don't use tools like he used, that will worn out your terminals.
i'm not sure who told you putting power to the ground was a good idea.
Eddie Suerte Felipe Iv'e taken off my battery cables before & my Radio settings stayed the same etc.No problem with it.
hi please i have aqustion..i have ford galaxy 2.0 diesel 2009..last week the temperature gage goes high till 110 while I am in traffic jam i stopped immediately the engine a little bit warm but fan doesn't work? after i use the car without any problem till now i drive for long distance no problem. I don't know this happened shall i check the car ?
dayumm bro .. you made that light go away like "bye felicia "
Hi today I went to a car wash today and I got the place to clean my engine bay when they power washed it and after I went thru the car wash after I came out my gas tank lid was full open would the fan blow air into the cap or something now I still have the engine light on -_-" & my exhaust now is making a popping sound would you know what it means?
2004 Mazda tribute ES V6
Modern engines should NEVER be power washed because of the sensitive electronics on and around them.
Yeap...time to go and get it inspected...HEHE
170324341a
Here on the front range in Colorado (9 county area) if they even see a check light on you'll never make it to testing, and no charge either.
170324341a good thing for me haha i have a 91 celica
Hi guy, this works of course. My Mazda 6 check engine light came on at 30,000 miles and I sprayed the Mass Airflow Sensor (MAF) down with some MAF cleaner and then reset by disconnecting the battery terminal. Engine light never came back. Just FYI.
Will that work on vw passat 2002
+Robbie JK
Resetting the light didn't fix it though. It would have gone out in a couple of drive cycles if it was just a dirty MAF. All this does is delay your ability to pass an emissions test until it triggers again and you fail anyway.
In your case, you had a problem that cleaning the MAF helped alleviate. My tester has several thousand test parameters, depending on vehicle complexity, there are a LOT of things that trigger a CEL besides a MAF, in fact the MAF is a rare one these days.
Being a former Ford tech (Ford is the same as Mazda for most of the engines and drive trains...AND chassis!) I clean my MAF every 6 mos anyway, it's a Ford/Mazda thing, they work forever but do need periodic cleaning.
+Delanie Epps Might do, but only IF you have a dirty MAF that is triggering a code or dirty enough that something else triggers a code easier than normal. Be aware though that there are a few thousand codes and even more reasons they trigger.
ozmedia OK thanks you, And it worked, car needed to be clean 😂
Good technique. Most cars today needs a scan tool to trouble shoot the check engine light and to reset it. The negative battery technique don't work for them. Regards,
Evaporation leak codes can be anything from faulty gas cap to vacuum hose in engine compartment after repairs if you are doing the job your self and taking the ground does not reset the light take positive off and turn ignition to accessories or run. live it like that for a minute or two light should go off
