Decoding Fault Code P12F4: Understanding The Issue And Its Implications
The P12F4 fault code refers to the Cylinder Deactivation Exhaust Flow Valve Feedback Circuit having a low duty cycle on a specific bank. This valve is part of the exhaust flow control system, which is responsible for tuning the exhaust note of the vehicle.
The Powertrain Control Module (PCM) constantly monitors the Cylinder Deactivation Exhaust Flow Valve to ensure it is functioning within factory specifications. When the PCM detects that the valve is not operating correctly, it triggers the P12F4 fault code.
This code indicates that there is a problem with the feedback circuit of the Cylinder Deactivation Exhaust Flow Valve, specifically on the bank mentioned.
