Go to Autozone and have them read the codes for free.

There should be a different light for the gas cap that says "Check Filler Cap".
The last time my (SES) Service Engine Soon light came on, I went to AutoZone, they read the code for free.
Then I came back here and searched for the code to find a resolution.

if you plan on keeping the car for more than a year, get a peake code reader.
Having your own reader will save you time; given it's an aging/older car it's likely that the SES light will come on with increasing frequency.

The same happened to me today, went to Autozone and the code was 0430,
Faulty Catalyst Converter

What I can do now ?

One stupid question, one week ago I do the Tee Mod, this can be the cause ?

If I replace the C Converter, the light disappears or I need to go to the dealer

Thanks,

Ok, yesterday I was so upset that coud not understand your message, now I have the things a little more clear.

First, about the readings I need to get a good scan tool first in order to avoid some misunderstanding of the generic readers right ?

What is a good afordable recomended reader, please keep in mind that I have 2 cars, mine ( 330 xi 2005 ) and my sons car ( 328 i 1999 )

Thanks,

If you don't have your own service station - go to your dealer hook it up to service station there. They will tell you what is wrong.

See, Drew, it gets very entertaining here too!

OP...you know there are like 10 billion reasons you could get code...but you can also, nothing personal, use all your senses. I know you get that fog of 'wtf happened to my car...god hates me,' but sounds like you're regaining your sense now.

Work up from simple to complex. Eliminate easy to eliminate things...use flashlight. Not something crummy, but a genuine XL50 maglite or something with 100 lumens...look in engine bay...read fanatics...look in engine bay.

Apply appropriate knowledge and tools early and often...and believe it or not, some here think I'm incredibly polite! LOL

There are only two fanatics here that know what your issue really is...I hope you'll hear from one of them!

Doug

You already got the code read, you don't need any other code reader. You got the code P0430, it is most likely your post cat O2 sensor failing and not reporting the cat efficiency to the computer, hence the low efficiency warning.

After that deep breath check out the post after your original, where the nice fanatic pointed you here:

Finally, THIS IS WHAT HAPPENS WHEN YOU THREAD JACK SOMEONE ELSE'S ISH. People don't differentiate your post from the OP's question. Because you jacked someone else's thread we get confused, and you end up getting bad advice. Next time you have a problem start your own thread.

Well my friend I accept your comment . and for the next time will follow your recommendation, I only did this because we start with the same problem, and after hours of searching, really hours of searching and found all kind of stupids threats I though was good write on this thread. My intention wasn't jacked Nicare's thread.

Now I think he has a good idea what to do.
