I will try to describe it best I can.
I am looking at my motor and find a plug just hanging on the back side of my motor and I don't know where it goes to.

I comes froma wiring harness that is on the top left side (passanger) of the car. There is a very thick bundle that runs across the top of the timming chain cover. At the back, near the firewall there is a smaller bundle that heads to the back of the motor. I then attaches to a small box (about the size of a box of paper clips) that is attached to the rear head then it continues to a 6 wire plug.
That is the plug that I have no idea where the hell it goes.







Can someone look at their car and tell me where it should go.

Just in case 2000 Max, like everyone doesn't already know that with me.

 

Come on over 40 views and no help. I know a bunch of us have pulled motors on here. Someone should have some idea.

Help please.

 

 

^^^what he said. theres probly 40 plugs that match that description

 

Yep, got me confused. Need pics

 

I'm thinking probably something with emissions?!?

 

I found the part number to the wire 24079-2Y900. It is a engine wiring harness and it is associated with theinjector harness.

 

OK I have pics up.
No one has any ideas? This is really kicking my a$$ that I can't figure this out.

Help, please.

 

Looks like a diagnostic port to me.

 

ok it goes to the egr valve check and see if thats plugged in your car has an electronic egr valve

jeff

 

So the other end should go to the EGR? Where? I am going to look tomorrow but a heads up would be good.
And thanks for the information

 

the egr valve is located under the intake flex hose it has 2 coolant hoses small that go to it and the top of it is gray plastic

 

Thank you very much. It was exactly that. Right below the unit were the 2 hoses go into there was no wire coming out of where a plug belonged.
I guess when Nissan put my new motor in the left that unplugged along with all the other stuff they messed up.

Nismotech1 thanks once again. Hopefully this will take care of my idle problems and the car dieing when I pulled up to a stop or red light.

 

my pleasure bro i've done all kinds of stuff to these cars, i work for a nissan dealer so i knew when i saw it what it was for. i'm just glad i could help..

 

I know a clogged EGR can cause those issues Gabriel, so an unplugged EGR valve probably defaults to closed and would do the same.

Good find and good help from Nismo.

 

I am just surprised that it did not throw a code.

 

Me too.....
