2002 Accord EX 3.0 V6

What is this part and what hose should be connected here. Engine has been throwing a P1339 code and P0505. Changed out the IAC and cleared the P0505 but still working the misfire. Noticed this nipple



without a hose on it and it has suction into the engine. Can’t figure out what line should go here and cannot find a loose vacuum line. Help!!

 

One port goes to the fuel pressure regulator and the other goes to a check valve that leads to the vacuum tank.

 

I tracked the one port with the hose on it and it does for to the fuel pressure regulator. The other one should go to the check valve but the line from the check valve is already hooked up at another location.

Is this wrong. I have not removed any of these hoses.

 

On older accords, each vacuum hose had a number printed on the hose. They also had a sticker under the hood showing the vacuum hose routing with those numbers. You might want to check if your accord has this.

I attached a picture from the pdf I'm working from. Hopefully you can trace them. Maybe post the first 12 digits of your VIN, so we can verify you aren't driving an 03, since 02 was the last year of the 6th gen accords.

I believe what you have circled is the engine mount control solenoid valve.

 

First 12 of VIN 1HGCG16572A0. I will look for the diagram under the hood. Additionally after looking at the diagram I lost cruise control about 6 months ago and started getting intermittent codes for the egr and iac valve.

 

You have an 02 accord. Trace out the vacuum hoses first to figure out why that port is open, then you should troubleshoot the other items individually.
