The Chevrolet Malibu's code P2646 often signals a problem with the arm actuator system, possibly due to it being stuck or malfunctioning. The main culprit is likely the oil control valve located near the engine. To troubleshoot, start with a thorough cleaning of the solenoid valve, which regulates oil flow into the engine. If the issue persists, the arm actuator system is likely failing. This system, under ECM control, manages oil flow to vital engine components. Continuing to drive with a faulty arm actuator for prolonged periods can pose serious risks.
