The P12F7 fault code refers to the Cylinder Deactivation Exhaust Flow Valve Closed Position 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 used to tune the exhaust note. The Powertrain Control Module (PCM) is responsible for monitoring the Cylinder Deactivation Exhaust Flow Valve.

When the valve is not functioning according to the factory specifications, the PCM sets the P12F7 code.

This code indicates that the exhaust flow valve in the closed position bank is not operating correctly. If you encounter this fault code, it is important to have the exhaust flow valve inspected and repaired by a qualified technician.

Ignoring this issue can lead to poor engine performance and potentially cause further damage to your vehicle.
