SES light: Got the code-update!

PeteG · #1 10-26-2006, 05:14 PM

About 4 weeks ago, my "service engine soon" light came on. The car was runnining and continues to run smoothly as before, with no noticed performance changes. I thought at first it could be the old "started the car with gas cap not closed" when my wife got some gas in it, but I don't think that's it. It's been 4 weeks and I drive it daily.

I have an appointment at the dealer next Thurs to diagnose, perhaps fix the problem. What things might it be? It's an '01 3.0i w/ about 87k on it. I am the original owner.

Thanks, gang!

Update: Got the fault code read at Autozone (thanks, Boston

). It read as an fault of the evaporative fuel system-major. Guy at Autozone said he had a similar problem with his GMC truck. Said the fuel cap itself may be faulty and not creating a proper seal around the filler opening, thus trigerring this fault. He says he can't get me the cap and to stick with OEM.

Does this sound right? Is it a DYI or should I take to the dealer? If dealer, anyone have an idea of cost?

Thanks again, X5World!

Why don't you bring it to autozone to have the code read and post it here.
Any suggestions woul dbe just a guess at this point without more info.

They can do that at Autozone? If so, will do.

mine was the cam sensor, but it could also be the o2 sensor as well

It is emissions-related, so could be any number of things. Cam sensor and 02 sensor are two of the common ones, mass airflow sensor is another. I would just take it to the dealer, but ensure that the work order is for diagnosis and not repair, ie you should authorize any repair before they go ahead.

If it were my, I'd reset the code and see if it comes back.
