P2176 MERCEDES-BENZ Description
The electronic throttle control system can monitor the system operation in manner ways. The actual position can be monitored by the Engine Control Module (ECM). This will be mapped against the desired throttle position. The current flow through the motor is also monitored. These data parameters allow very precise fault codes to be logged such as actuator stuck, ice blockage, unmetered air entering the intake manifold, etc.
