Hello, I was searching for the crankshaft sensor feeling around towards the lower back drivers side firewall and I noticed this line was disconnected and the rubber was fraile and falling apart. I'm hoping The Wizards of MBWorld can let me know where the location of this vacuum line plugs back into? I'm also getting a PO410 code on the Foxwell NT510 Elite OBD II Current Air system 'A' #1 Faulty Air pump #2 Faullty Air Bypass Valve #3 Open or short in the Air Bypass Solenoid Circuit. I have no clue where those parts are but I already replaced the damaged rubber hose line conectors. There are two 2" rubber hose at each end with a small blue air nozzle connector in the middle see attached pictures. The white vacuum line starts near the passenger side fuse box. Passenger side fuse box where the line appears to begin.. Even with the diagram I'm not sure where it plugs back into lol .plastic clilp over the line near the fuse box Drivers side: White vacuum line going through top firewall railing. I placed it straight at the end just for the picture Rubber hose connectors loose,fraile and falling apart. I know the whole engine needs cleaning.
I hope this is the cause of the code and not something more serious. Does anyone have a picture of where it connects?
Thanks in Advance

I think that connects to the throttle body. I would have to take of my intake to see it (I have a different model than you) and I might do that in a couple weeks and try to let you know, but look around the throttle body/intake area.

I felt around in back of the throttle underneath a plastic inverted cover. You can't see underneath it but you can feel there is one T-rubber connector and it feels like a insert nipple next to it. I'm not sure if it's it but I plugged it in. & reset the code. If you happen to take a look let me know Thanks for responding.

@2esky Check out the video at 1:22 it shows where it plugs in also I hope the pictures help. @RollTideW163 I found it You were right, it is in that location Thank You! close to the back firewall on the drivers side. Follow the white line to the blue hose connecter right under the drivers side firewall
It plugs into a round insert nipple thats under a plastic cover. You have to feel up under it with your fingers and push the hose in. Notice there's 2 hoses, insert yours into the empty plug.
