Depending on the engine fitted

P0660 - Intake Manifold Tuning Valve Control Circuit Open Bank 1

I am tipping it's the Plug at the back in the centre of the manifold that has not locked in place correctly,

There is a Plenum/intake manifold butter fly that will rotate according to the ECM commands,
If that ECU doesn't get a reply, possibly that is why its triggered the P0660.
