How did you check the ICV?
Did you do an Ohm test on the terminals? What were the ohm readings?
Did you just shake the ICV and because you heard it rattle you determine that it was O.K.?

When I had the PO1093 error code I replaced the IVC, I didn't bother to clean it.

ICV should make a buzzing sound when you turn the keys to the run position, but do not start the engine. Does your ICV buzz?
