The P12FC fault code refers to a problem with the Cylinder Deactivation Exhaust Flow Valve.

This valve is responsible for controlling the exhaust flow in the cylinder deactivation system. It is located at the inlet of the muffler and is used to tune the exhaust note of the vehicle.

When the Powertrain Control Module (PCM) detects that the Cylinder Deactivation Exhaust Flow Valve is not functioning properly and is stuck closed, it sets the P12FC fault code. This means that the valve is not operating within the factory specifications.

If you encounter this fault code, it is important to have the Cylinder Deactivation Exhaust Flow Valve inspected and repaired.

A stuck closed valve can affect the performance and efficiency of the cylinder deactivation system, leading to potential issues with engine operation.
