P0664 after new plugs/coils?
P0664 after new plugs/coils?
Search surprises me no hits on P0664, which is OBD-II Trouble code: Intake Manifold Tuning Valve Control Circuit Low Bank 2. Thinking I left a wire or vacuum hose off but I don't see anything obvious?

I have several threads about IMT valves. If you haven't replaced the IMT o-rings yet that might help. I believe the wire harness may have come undone or faulty.
Advance search for "IMT o-rings" by "joycesjag".

Glad it was an easy fix.
