What Does the P2101 Mercedes-Benz Code Mean?

This fault code is stored in the Engine Control Module (ECM) when a fault is detected with the Throttle Positioner Motor. The ECM monitors the current flow through the motor and if the current flow is exceeds a predetermined limit this fault code is logged. The ECM uses a comparator circuit to monitor the current flow. A mechanical detect within the throttle valve assembly can effect current flow. Mechanical condition of the throttle valve assembly should be investigated before any electrical fault finding procedure.
