The P12ED fault code refers to a problem with the cylinder deactivation exhaust flow valve feedback circuit.

This valve is responsible for controlling the exhaust flow and tuning the exhaust note. The Powertrain Control Module (PCM) monitors this valve and sets the OBDII code when it is not operating within the factory specifications.

This code indicates that there is an incorrect frequency detected in the feedback circuit of the cylinder deactivation exhaust flow valve.

It is important to address this issue to ensure proper functioning of the exhaust system and overall performance of the vehicle.

What are the possible causes of the automobile fault code P12ED?

If you see the engine light or service engine soon warning light on, the fault code P12ED 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 valve circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage or corrosion, and check for broken or bent pins. It’s important to address these possible causes to resolve the fault code.

How can I visually inspect the wiring harness and connectors to fix the P12ED fault code?
