Hurdigurdiman replied to dwightolson's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)So Dwight, did you actually find the problem why the idle was surging at stop? Mine is the same year and model Carrera and acting up just the same as yours .
The AOS has a rubber diaphragm inside and a rubber boot on the outside bottom part, which attaches to the crank case. To remove and replace this bottom accordion rubber boot, best to change the AOS at the same time. The boot is already attached to the bottom of it which drops over the securing bracket with a quick release bottom clip. . If you want to attempt to change it alone, it's a real PITA as you will be working one handed on your back. No need to remove the wheel. Jack the back up, slide in head first on your back till your head is level with back wheel and you will see the boot high up under the car. I advice you to put a coating of oil inside both ends of the new boot before attempting to put it in place. I managed to get a quick release metal clip on the bottom BUT only a Zip tie to the top. Got my boot cheap from Pelican along with 2 quick release type clips but could only get the bottom one on. That's why I used the zip tie on the top which I put loosely around the boot before putting the boot in place. Then pull hard on the top zip tie. Let me tell you, only a magician could get both quick release clips in place. Move the electric plug to the right for more room for your one hand.
JayUSA123.. I have the same problem and no way can I find the answer. I want to know whyI can blow through the vent line both way passed the blue valve. I can. So is my blue valve bad or good? Did you ever solve your problem? Thanks in advance. Mike
Hurdigurdiman replied to Hurdigurdiman's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)the 466 code is gone but I have 2 more up or pending p1124 and p1126. I would really like to find if my blue valve is at fault but no one wants to help me on this subject. Does anyone read these posting. Its been up for a month. ? I have seen it for sale at almost $200 but I need to know if mine if bad first. Obviously the seller will not help me. They only want to sell the thing.
TO REBORN996 .... First and foremost be very careful not to snap the white plastic connector on the 10-0-clock position of smaller white circle. On mine which is a 99 996 Carrera at the 10-0-clock position you see the black tube leaving the small white round thing? Feel along that line under the lip towards the steering wheel. About 2 or 3 inch in you should feel something like an electric plug . Pull that towards you so you can see it. Go gentle or you will snap the white connector on the side of the white circle. You are now looking at the tank pressure sensor. A single phillips head screw holds the sensor. Undo that and pull the sensor which has a rubber grommet around it, free from its holder and exchange. Good luck.
LOREN.. I have the same 99 996 as yours. I am wondering should I be able to blow each way through the line and blue valve in your photo? It is called the Vacuum Control Valve #9 in the diagram above. I am getting po446. When the line is disconnected top and bottom and taken from the canister. I can blow each way through the line passed the blue vacuum control valve. No electrics attached to the line. Should I be able to do this? I expected it to be like a 'one way' valve but mine is not. That fact may be why I get the 446 codde The next time you are in there, could youy please blow through the line for me and let me know the outcome. Thanks in advance.
There is a 'shut off' valve with electric plug on it, top front of charcoal canister which I changed along with the pink valve on top of canister (maybe called purge or vent valve) a double type valve about 3 months ago. CEL still comes on. That's why I am really interested in this blue thing on the side of the canister. It does NOT have an electric plug to it. I disconnected the pipe top from the pink vent thing and the bottom with the blue plastic type round valve set in the middle of this length. I held the pipe in my hands and can blow each way past this valve with ease. I would have thought I could only blow one way as a kind of a one way valve thing but NO. Is the thing GOOD or BAD? Whats this for?. Why is it there?. What is the name of the thing?. I seem to remember someone said it is a 'check valve' but it doesn't seem to check anything only my patience as far as I can tell. I put the part # on google NOTHING. Oh yeh some bloody oil well in Texas somewhere came up. Very helpful lol.
Hurdigurdiman replied to Hurdigurdiman's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I really need to know the answer to my first message as I am in the middle of smoke machining the evap system. The question being. I can blow air and smoke BOTH ways passed this blue valve. I need to know if this blue thing is good or bad as I think I should only be able to blow ONE WAY not both ways along the pipe. Otherwise why is it there in the first place. What is it supposed to do? THERE IS NO ELECTRICAL CONNECTION TO THIS PART. HOPEFULLY SOMEONE FROM PELICAN PARTS CAN HELP ME AS I AM USING ONE OF THEIR PHOTOS TOP DISPLAY THE PART (BLUE VALVE)
Hurdigurdiman replied to Stefan's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)you might laugh but fish tank air line is the exact fit. It's soft enough the bend around places and cut to length longer for easier movement. It tightly goes over the existing brittle parts of the evap system behind the alternator. Some say that gas fumes may rot the fish tank line but it is real hardy stuff.
Hurdigurdiman replied to goldenwarrior1's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)that's good to know JFP in PA. Thanks so much. I have an indi who will clear my po466 with his tool lol. I have done lots of testing and the likes. Not found any vac leaks but still working on them with a hand held vac pump.
Hurdigurdiman replied to goldenwarrior1's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)what happens if you clear the code by disconnecting the battery for 15 mins or so. Does that permanently delete the code or will the code pop up again. Does all codes have to be deleted by a durametric type device? My small durametric will not allow me to clear codes. I have a cheap generic one. So to remove the CEL I use the battery method. After another 30 miles, up the samwe code comes again. I ask myself" Did I actually cure the fault and is that the old code popping up the CEL from memory. Can anyone answer me that question thanks.
Hurdigurdiman posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I have a code po446 and CEL up right now. 446 indicates a vent circuit malfunction on the EVAP system. I am trying desperately to track the fault. In the photo you see the black charcoal canister with a green arrow pointing to some sort of blue valve. Its that valve I am interested in. I have disconnected the top and bottom purple and red arrows and hold the line (including the blue thing) in my hand. I am able to blow each way through this line. That confuses me as I wonder now why it is in the line in the first place if I can blow each way. No electrical connection to the blue thing. I would have thought I could only blow one way. Does anyone know what its called and what its there for? Is it a good one or a bad one. I hope its a bad one and then my problems will be solved.
Hurdigurdiman replied to siddharth's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Loren opr other readers, I am testing an electric change over valve which has two small inlet pipes situated at the top of the alternator front. One of the inlet pipes sticks out from the center and the other from the side Of the device. With no volts to the device I use fish tank tube attached to the side inlet and blow smoke which comes out around the round cap but does not from the other inlet/outlet pipe. When attached to the center and no volts I cannot blow through it. With volts attached I hear a click and the smoke goes from either inlet to outlet. I think the valve is working correctly but am worried about the smoke coming from around the cap. Is air supposed to come out around there? If not then I need a new valve. Thanks in advance.
