4 codes P0171 P0174 P2195 P2197
I have 4 codes on my 2003 Navi. After searching through my engine I found this vacuum line off. Only problem is I cannot find where it goes. I taped it to keep dirt out of it. I took pics and can email them. Can someone look at their Navi and help me find where it goes please?

I couldn't get a good pic but it looks like it goes down towards the firewall along the block. The connector on the end looks like it could goto a sensor. I'll crawl under the suv tomorrow and take a pic of it.

OK, I finally followed it. It goes down and takes a 90 degree turn towards the front of the motor. Along the bottom of the rad and up into the vacuum splitter of some sort. Turns from plastic to metal below the splitter. Its the top left one. Here is the pic I took of it. Hopefully you can tell me where the other end goes.

This is the ABS Control Unit and those metal lines are brake hydraulic lines, they can't be connected to the plastic pipe you found on the right side of engine. If you follow the two lines I circled (easiest to follow) you'll see that they connect to brake master cylinder.

I followed the line again and it goes to the drivers side brakes. As for my 4 codes. I fixed them. I changed the plugs and found and elbow under the plastic cover on top of the engine that was worn through. Apparently that's a common problem. As for this vacuum line, I found a spot that it may connect to but I'm guessing. I've added the pic where I think it might go. It's right above the trans dip stick.
