WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

The cylinder deactivation solenoid controls the flow of engine oil to the affected intake and exhaust rocker arms effectively activating and deactivating that cylinder when only minimal engine power is required.
