After two weeks of ownership...
 

MY CEL Came on. I had it scanned and it generated code P0446. Lucky me its nothing too serious. I did some searching and I came up with the following:

Symptoms: There will be no obvious symptoms to driver, other than Malfunction Indicator Lamp (MIL) illumination.

Causes: code P0446 could mean one or more of the following has happened:

Faulty vent valve
Open, short or excessive resistance on Vent valve control circuit
Blockage of vent valve
Bad PCM

Possible Solutions: With a P0446 OBD-II trouble code, here are some things to try:

Replace Vent valve
Repair open, short, or resistance problem in control circuit
Repair open, or short, or resistance problem in power circuit
Replace PCM

My 2000 Boxster had over 2 times the miles and never had a CEL light come on, this one has 58K and Ive owned it for two weeks and it came on. ERGH. Anyone else ever have this code pop up?? Im hearing a new gas cap may fix the problem...

Thanks

Change your gas cap. :)

Just ordered a new one today! I'll keep you posted.
