What is Benz code p2001?

The Benz code P2001 refers to an issue with the intake manifold runner control (IMRC) system, specifically indicating that the intake manifold runner control actuator is stuck in the open position. This can lead to poor engine performance, reduced fuel efficiency, and increased emissions. The problem may be caused by a faulty actuator, a vacuum leak, or issues with the wiring or connectors associated with the IMRC system. Diagnosing and addressing the underlying cause is essential to restore optimal engine function.
