As titlte states, car is a 98 Ex, I have been dealing with CEL code P1457 and I have done everything I can to solve it with no luck. Today I took the cover off the two way valve assembly attached to the fuel tank and discovered that there was a hose terribly dry rotted. I will provide a picture pointing out which hose I replaced.

My question is, the hose I replaced goes from the Fuel Tank Pressure Sensor to a "Y" vacuum joint and to the chassis to a nipple looking outlet. When I looked at the "Y" there was no vacuum hose going to one of the three ports on it. Is there something supposed to be hooked up to it? I looked everywhere around and couldn't find anything that can hook up to it. Is it just a fresh air intake per say? Below is the image and the parts I am talking about.

Part 53 is the hose i replace, and part 8 is the "Y" that has an empty port on it.

 

The "Y" doesnt have a hose on it or the hose from the "Y" isnt hooked up to anything? What it looks like to me is that the hose #53 goes to a possible plug or breather #6. The hose #7 goes to a vacuum solenoid #1. From there i cant see where #6 or #1 goes.

 

The "Y" has one end going to the fuel tank pressure sensor, one end going to a port/"nipple" on the frame rail of the car(with a hose of course), and one end is just there with nothing going to it or from it.

 

so are you referring to the side that goes to hose #7, hose #53 or the other side?

 

I'm not referring to either of the hoses. Sorry if I am unclear. I replaced hose #53 due to it being torn. I know that goes to the "Y", I also went ahead and replaced hose #7. Now my confusion is that the bottom port of the "Y" has no hose going to it, it's just there.

 

Ok. Now I understand. There should be another diagram that goes with the one you have there. If you can find it or the legend you should be able to find out where it goes.
