My check engine light is on so I had it tested and the code that came up was P0446. I tested the VSV and it is defective and I have ordered another one. Do you have a diagram showing how the hoses connect? I am pretty sure I will be able to put it back to how it was before but I just want to make sure I do it correctly.

Thanks,

Brian

The solenoid has only 2 hoses. The one with vacuum from manifold is connected to the outer port of the solenoid.

Only 2 are used. The top is for vacuum line. 2nd one is to the actuator. The bottom is for breathing whereby a filter is usually attached.

Thank you very much for getting this to me. I noticed the diagram is for a LE. Would this be the same for a CE? That is what I have.
