Electrical pin outs for purge valve
Looking to see if anyone has the ECU pinouts for the vent line purge valve? I'm getting a P0444 and an indy shop says the plug routed to that seems way too tight to be the correct plug. Does anyone have access to the ECU pinouts from this purge valve to the ECU? I found several ECU diagram PDF's but they do not show the wiring for this specific part.

If anyone has the full ECU pin outs, I can do the leg work to find the pins.

Pinouts here: https://www.6speedonline.com/forums/...g-diagram.html what you're looking for: C3 on the ECU side ... pin 9 on the first round connector engine side ... Violet/Violet wire https://cimg1.ibsrv.net/gimg/www.6sp...759be3140.jpeg https://cimg4.ibsrv.net/gimg/www.6sp...c47221d67.jpeg https://cimg5.ibsrv.net/gimg/www.6sp...af1c5738b.jpeg |

The connector prob isnt mixed up or you would have two codes because something else would be plugged in the wrong spot.
Also I found that same picture but I believe that is for the gas tank vent valve. That little valve you are looking for goes to the intake manifold so it should be the purge valve |

that’s a good point, but I’m getting a p0444 even after the Indy shop replaced the purge valve and carbon canister. They mentioned the harness seems way too tight. Because I dont think on the 997 it has a tank vent valve. I believe it just has the engine purge valve |

they replaced the purge valve in the engine bay? the picture that you posted?

we’ll be tackling this project this Saturday, any other ideas on the P0444 cel? The car idle hunts (sometimes, with the cel coming on right after), with similar symptoms of a vacuum leak. I would UNPLUG the valve and power it to see if it clicks. Make sure you didnt get a bad part from the dealer or part store. Check resistance from the main plug to the sensor plug make sure you dont have a break in the wiring. If you have access to a scanner can have a meter on there and see if the computer is even commanding the sensor on. PM and Ill give you my cell number if you have any questions you can shoot me a text |
I replaced the vent hose in order to correct a P0455 code..
https://rennlist.com/forums/997-turb...l#post13542347 see post #13 and #19 Worked like a champ, I bet you have some other issue. The connector just provided 12V to cause the hose to flow air or not. Mine was easy to check. |
