Evaporative Emissions Check Engine Light

[GIOSALVA1]

Hey I live in long island and I was wondering if I can bring my car to your brother, because I'm having the same problem. Thanx

[sodaspider]

i found that my truck had tiny rust holes in the tank that actually couldn't be seen until layers of rusted steel flaked off so i had to get a new tank, but yeah i hate when evap codes come up and that's the only thing wrong when the engine light is on

[sodaspider]

i was a mechanic for 5 years and i always hated dealing with evap codes. it's the ONLY system on a car you can't just work on and say "it's fixed" and send away. you gotta fix something, hope that was the problem, and then tell them to come back IF the engine light comes back on. People really don't leave your shop with confidence when you tell them that, then you gotta spend another 10 minutes explaining the annoying system and how it "works"

@sodaspider

Yes, you are right.We had to drop the gas tank in order to find some rust holes which were on top of the tank. Although they were only tiny pinholes, they were only discovered as the last thing and thank God for silicone which we used to seal them!

Thanks for viewing and commenting, I am glad to be helpful.

Great video. I have a 1998 Hyundai Elantra and am wondering where exactly is the FTP SENSOR located ??

[LongIslandEddie]

@nightwingmetal

The FTPS is at the rear, under the trunk, look back to 7;11 of this video and you will see it, but it is mounted on the top of the small oval shaped, tank-like cannister. It is easy to find if you can get the car on a lift, because there really isn't a chance for you to even see it if you are using a creeper, the car sits too low. Also, it has an electrical lead running to it, one of the only underside and at rear electrical tethers. I paid $92.00 for a new one, try a junk yard.

Truly, an awesome video, Eddie. Thanks ... got a P0442 I am about to work on and this gave me the information I needed. :)

[chevycamaro1976]

[gammatnt]

hey bud thanks for your info its very helpfull and very good of you to take the time for others,I found myself having to get back to mechanics after 15 years,I was in the building trade up till now , work dried up in Ireland so I had get back into the mechanic s again I am trying to refresh my brain on the old as well as all the new and thiss is very help full thanks again

[LongIslandEddie]

Well, Thank You! I am always happy to find anyone who genuinely appreciates any video that I have posted and when they do, I'm pleased to get their feedback.

I hope that you make a successful recovery from the closing out of the building trades into the mechanical trade and that you do not suffer too much economic hardship while making the transition.

You'll always find helpful information out here on the internet when you are smart enough to take the knowledge and use it for your betterment!

[tooblood08]

I dont have a brother as a mechanic so I don't quite know what to do. Do you have any suggestions of the first steps I can take to get this fixed? Any feedback would be greatly appreciated.

tooblood-

Guy, without a connection to a decent mechanic, i really don't have any usable advice to give you. one very important consideration is that you need to be under the car in order to access the suspected area of your problem and without a greasepit or a lift, I don't think that a creeper would be of much help.

Get to a friend or a mechanic who can put a scan tool onto your ECM and provide you with the particular code that is causing your MIL to go on. This is necessary because you will

[LongIslandEddie]

have no idea of what part of your system is failing. It isn't necessarily the emissions system that is causing the check engine light to be illuminated, in today's vehicles, the evap system is only one of several systems which are reflected in a MIL indication. Until you get a diagnostic code reading, you will have no idea of why the light is on but thankfully, there are places which will give you a free reading as a courtesy. Once you get the reading done, copy the codes and post them here, to

[LongIslandEddie]

this thread and I will give you further direction. Also, the beauty of the internet is that there is a wealth of information to be gleaned out here and I spent many long hours gaining a bit of knowledge before I was able to (with the help of my brother), move ahead to the point of resolution. Check the codes because if you were able to pass your inspection, chances are that you were not dealing with an Evap Sys problem and there are several other monitors within the system which may be the

[LongIslandEddie]

cause of your problem. Depending on the state that you are registering the vehicle in, the inspection requirements may vary but every state has stringent regulations respective to the Emissions standards which is because of Federal mandates that have become state law which apply to maintaining air quality, fuel efficiency and carbon emissions.

Please, for your own benefit, GET THAT CODE READING! Even if you have to go to Sears or Pep Boys and buy your own scan tool, this is first base for you!

[tooblood08]

OMG. I have an 04 Nissan maxima and I belive that I have the exact same problem right now. I can't get rid of that check engine light and that code for anything at all. I also get this pop sound like its coming from my gas tank like a soda can. Ive been from one shop to the next. The last shop just fixed everthing they could, put a new gas cap on and reset it. I passed the inspection but the light is back on again.

[Aussie50]

Good work man! you put a lot of detail into it!

Although we don't have emissions inspections over here (they are briefly checked if a vehicle is being re-registered after a period of being un-registered) I can't stand emissions systems, my BMW has miles of tubing, valves, vacuum and electrically operated valves that can be a real pita to fix.

Unfortunately the ECU won't run if I uninstall it all either :(

[LongIslandEddie]

Well thank you Aussie! You are the first commenter and I appreciate that you took the interest to watch a 15 minute clip. I am out of work now (the economy here) and making this video was a way to keep my mind tuned, keep myself from going batty for lack of constructive activity!

There so much more that I would like to be able to touch on but it will depend upon whether or not anyone needs to know anything more and also whether I have the answer for them.

Thanks for watching, Aussie50... Eddie

[Aussie50]

I'm surprised you got 15 min on! normally the cap is 10 min?

my work is slowly diminishing too sadly, I make videos as I do my hobby work, trying to compensate with scrap metal recycling and keep my sanity

[LongIslandEddie]

Aussie-

The cap is set at 1GB if a user has a "directors" account. It used to be 10 minutes but since youtube was assimilated with Google, they've changed a few things. The reason for the length of this video is to give readers a chance to read each panel at a reasonable rate although, if there is any information that needs to be saved, they may just pause the video and do a screen capture and save the info to their hard drive. I hope that you get to keep your sanity, forever!

Thanx
