Hey guys,

I have a 08 uplander. It just got a check engine light at 45,000 miles P2070 - tuning valve stuck open.

ANyone know anything about this?

sounds semi expensive...

 

I would suggest having the vehicle checked by your local dealership (unless of course that is where you had your vehicle checked for codes). You should still be covered by the 5 year 100,000 mile powertrain warranty which may cover you for this kind of a fix, under normal circumstances. I hope this helps and if you run into any problems please contact me through this forum.
