In the past two weeks my '04 CTT failed to start right away immediately after fueling up. The second time it happened to my wife and coincidently someone at the pumps just happened to have code reader on them. They were kind enough to offer assistance and the proceeding codes were read; P0441, P0011, P2403. Can someone help me understand these codes and prospective trouble shooting I will need to do so as not to leave wife stranded. Thanks in advance

 

So, as usual due to time constraints I didn't look at codes list on site and rushed to asking forum. I found the codes in the OBD section, so I understand what they mean and I now ask is there anything I need to do about them beyond the reset that was given at gas station? one code was cam position and the other two were emissions related; (system purge flow and leak detection pump)

MY 2006 CS just started doing this and giving the same codes. Had to floor throttle everytime I filled up fuel.

I was thinking it was EVAP purge valve. I put a clamp on the vacuum line between evap valve and throttlebody then went and filled up. Problem solved.

Have valve on order, around $130 and easy to replace. Note doing this will also cause evap codes but will start every time and run well.

The other thing I noticed was horrible fuel economy.

Hi Mattehlers. Do you happen to have part number for evap purge valve and location of the valve?

Thanks

Item number 3. 

It sits about 6" to the right and 2" lower of the throttle body.

Hi Lewis. Thanks for the info. My vehicle is a Carter's S. in mattehelers post he said it was his 2006 cs. I guess that was a Cayenne. I didn't pay attention to the forum I was in. Still nice of you to help. My bad.

      2007 997.1.  Carrera S Cabriolet
      After I refuel the car it doesn't want to start.  The engine cranks but it won't fire.  It sounds like it needs gas.  I put my foot on the accelerator and floor it and the car will start.  I then have to keep giving it gas for a few seconds or it will die.  Once it get going it runs fine.  It recently gave check engine light and code is P0441.  "P0441 Evaporative Emission System
      "Incorrect Purge Flow Present"
      I've researched this and it seems that it is a faulty purge valve or fuel tank vent line valve that needs to be replaced?  Conflicting information on whether the 997 has a fuel tank vent line valve.  Has anyone had experience with this?  Help would be much appreciated.

      2002 Boxster S, 90K miles, 6 speed. History over last year included an IMS bearing failure and subsequent engine rebuild.
      Symptoms: Car started throwing codes 1128 and 1130 a few weeks ago. Starting has always been very easy on this car, but along with the codes it became very labored- starts to crank very slowly for several turns then fires up. Idle seems slightly rough on occasion. I've also noticed an odd smell when I climb out after driving; hard to locate but most prominent in rear of vehicle and suggests something hot or burning.
      So far: Cleared the codes the first time it happened, and they reappeared around a hundred miles later. Cleared them again, same result. Did some research which suggested MAF sensor might be at fault; replaced that and symptoms reappeared again. I've since cleared the codes again, and once again they've returned.
      I've done a bit of research and it generally suggests MAF or an air leak into the oil system. Cap is on tight and AOS was replaced a bit over a year ago; I do seem to have a hard time getting the dipstick to seat properly and stay seated, but the last time I got the codes, I checked and it was down in it's receptacle with the O-ring in the neck where it belongs.
      Does anyone have suggestions where to go with this next? I've searched this and other boards and coming up blank.
      Thanks in advance.
      John
