Emission Check Engine Light

[newlife]

Hello, I am new to Remmtech and a new Porsche owner. I have a 2000 Boxter S which I purchased from a friend. I am the third owner. I had the local Porshe shop do a prepurchase inspection and everything was up to speed. Both owners prior to me kept all service records and the car is in "like new" condition. While I was in the garage checking out the car I opened the fuel cap, just to check it out. The next day when I started the car the "check engine light" came on. I drove it today and the light remained on. Like I said before there are no issues with the car. I am thinking because I opened the fuel cap it may have tripped a sensor. Does anyone have any advice as to where I should go from here. Should I drive it down to the Porsche shop or is there something I can do to make the light go out. Thanks

If you have the 4 digit radio code you can remove the negative battery connection for 5 minutes then re-connect the battery. If the CEL light is not flashing you're not hurting anything. I'm not sure where Alpine Calif. is located but you may find a Renntech Board Member located nearby to check with their Durametric tool that may be able to give you a more complete diagnosis.

Thank you Kbrandsma ! Yes I do have the 4 digit radio code. And I am assuming the negative battery connection is "negative"/black. And the CEL in not flashing. Alpine is in the back hills or San Diego County. Thanks again !!!

Or, you can go to Advance Auto Parts, catch them when it's not busy, tell them what you did, and they will clear the cose for you for free. You ca also buy any cheap OBD2 scanner that will clear it.

When you put the fuel cap back on did you tighten it at least three clicks? A fuel cap that isn't tightened will cause a CEL.

Hello, I tighten it only 2 clicks. But I did disconnect the neg battery cable for 5 min as instructed and that did the job. Thank you very much. Its no fun zippin around with a CEL on !

Sorry, but you need to read the fault code(s) - everything is just a guess without the fault code(s).

+1 on Loren’s comment. Clearing a code, particularly an unknown code (not read) is asking for grief. Take 5 min., get it read, and you will know what is going on…….
