Default Can someone tell me where this hose goes to?

Hi Guys,

I recently did a turbo swap and im throwing a p0457. There is no hose connected at the moment to the intake manifold where the green circle is. I covered it with a rubber grommet so nothing gets in, I just don't know what hose is supposed to go on there. I don't see any loose hoses in the engine bay, but somewhere to start would be awesome. I borrowed the engine bay pic from someone else, btw.








Thanks,

Grant

The valve (the black thing slightly to the left of your green circle) connected to that outlet is meant to regulate the gas/fuel-return-vapor from your charcoal filter located in the rear of your car. For the most part, it is an emissions-related feature and your car will still run without it. It is connected to the third (phantom) hard-line in the set of fuel lines below your intake manifold.

Your options:

1. If you want to fix it the stock way, reconnect the all the hoses as pictured above. Having said that, I'm not sure what you did during your turbo swap so I don't know if you have all the said tubings/connections readily available.

2. You could just keep that port plugged up and another port in the intake manifold slightly to the left and below plugged up, removing the above-mentioned valve altogether and have the CEL code deleted via your EM. You'll also need to plug the vapor-return line by your fuel filter; I plugged it with a bolt...

This is based on the information you've shared thus far. If you could provide more details, others along with myself may be able to help you out better.

By the way, don't damage the above-mentioned valve if you intend to proceed via route/option 1 as it will cost you more than a hundred bucks to procure said valve from the dealer...

I mean idk whether the hose connects to that valve. The valve is already connected to the intake, the manifold in the location on the photo, and to a hose that goes underneath the intercooler to a metal rail. Idk where the hose is supposed to connect to.

if you look at the intake manifold, just to the left of the tube you circled, there is a valve which is on a bracket which bolts to the intake manifold. The valve (purge control solenoid) is supposed to have two lines connected to it, the lower of which (iirc) is the one which goes to the tube you have circled.

Thanks guys for the responses. The guys at DPS figured out the problem, the valve was broken and no hoses came off of it. DPS replaced the valve for me for free! Thanks guys.
