Kia Troubleshooting Questions? Ask a Mechanic
Hello I will help you with your question,
The diagram that KIA shows is pretty hard to read. Do you only have that one or does the one here from Hyundai (click here) look the same as your engine. It should be as Hyundai was running KIA in '04.
Let me know if that matches what you are seeing. If it does we can work on the code.
The vacuum from the throttle body should be present at the top of the solenoid at all times the engine is running, if you suck on the the port on the top is should not be open when it is unplugged.
Let me know if the routing of the diagram matches what you have
Pictures of what you have?
Those are the KIA diagrams, so I have seen those, I was not clear though and was hoping you had a couple of picture of the manifold and the solenoid/throttle body?
Ok, that transducer also acts a delay, with crumbly lines no telling what was done before you got here.
Hyundai and KIA are very light on information in the service on this system so much that Hyundai made it part of training to get the info out. click here
I am going to look through a couple of years here and see what I can find that shows the parts of the system. In the Hyundai setup you pinched the green stripe hose which was a bleed off. Close that bleed and the valve would open and if the idle stumbled hard you know the vacuum part was working.
Give me a couple of minutes to check
This thread is always open for you to post to so I will watch for your post when you get a chance to check it out.
Did you see the correction to the manual where the solenoid is open with no power and closed with power?
The solenoid allows vacuum to bleed back to the intake until it is activated then the vacuum is strong enough to open the valve, open the solenoid and the vacuum to the valve is not strong. Kinda backwards but that is why you pinch the green hose the valve opens, you are doing the job of the solenoid.
Let me know how I can help
