The P12FF fault code refers to the Cylinder Deactivation Exhaust Flow Valve Actuator Performance Bank. This code is related to the cylinder deactivation exhaust flow control system in your automobile. The system includes valves that are installed at the inlet of the muffler and are responsible for tuning the exhaust note.

The Powertrain Control Module (PCM) is responsible for monitoring the Cylinder Deactivation Exhaust Flow Valve.

When the valve does not meet the factory specifications, the PCM sets the P12FF code. This code indicates that there is a performance issue with the actuator of the exhaust flow valve.

If you encounter this fault code, it is important to have it addressed by a qualified technician. They will be able to diagnose the specific issue with the actuator and take the necessary steps to fix it.

Ignoring this fault code could lead to further damage to your vehicle’s exhaust system and potentially affect its overall performance.
