What is OBD-II Code P28F6 – Engine Disconnect Clutch Actuator Circuit Intermittent
As a mechanic, one of the most common questions I get asked by car owners is what an OBD-II code means and how they can go about repairing the issue. One of the codes that I encounter frequently is P28F6 – Engine Disconnect Clutch Actuator Circuit Intermittent. In this article, I will break down what this code means, what causes it, and how to go about repairing the issue.
What is OBD-II Code P28F6?
OBD-II is an On-Board Diagnostic system present in all cars manufactured after 1996. It’s a system that monitors the car’s performance and detects any faults or issues within the various systems, including the engine and transmission. When the system detects an issue, it records a Diagnostic Trouble Code (DTC), which it communicates via a Check Engine Light.
P28F6 is an OBD-II code that falls under the Powertrain system. It’s a code that communicates an issue with the engine disconnect clutch actuator circuit. The code indicates that the circuit that controls the engine disconnect clutch actuator is intermittent or failing. The engine disconnect clutch actuator activates the clutch when the engine is idling. When the circuit controlling the actuator is faulty, it can lead to several issues, including stalling or failing to start.
