The P12FE fault code refers to the Cylinder Deactivation Exhaust Flow Valve Position Not Learned 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 is not functioning according to the factory specifications, the PCM sets the P12FE code. This means that the position of the exhaust flow valve in the cylinder deactivation system has not been learned by the PCM.

If you encounter this fault code, it is important to have it addressed by a qualified technician. They will need to diagnose the issue with the Cylinder Deactivation Exhaust Flow Valve and ensure that it is functioning properly.

Ignoring this fault code could lead to further complications and potentially affect the performance of your vehicle.

What are the possible causes of the automobile fault code P12FE?

If you see the engine light on or the service engine soon warning light, the fault code P12FE could be the culprit. This code is often caused by a faulty cylinder deactivation exhaust flow valve, an open or shorted harness, or a poor electrical connection in the cylinder deactivation exhaust flow valve circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, be sure to look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors related to the Cylinder Deactivation Exhaust Flow Valve?
