Code P2127 MINI Description

The accelerator pedal position is monitored separately by 2 individual sensors. Two sensors are employed to provide redundancy, implement the monitoring function, and facilitate recognition of malfunctions. The sensors register accelerator-pedal travel as angular deflection, with data being transmitted directly to the engine-management control unit as analog linear voltage curves for the pedal angle. Overall pedal travel is mechanically expressed as 16° ±0.5°.
Each change in the accelerator-pedal position is transmitted to the engine-management control unit with a maximum lag of 50 milliseconds. Sensor signals are transmitted in analog form. The engine-management control unit monitors the two input signals from the sensors and compares them for plausibility (factors such as mutual synchronicity, linearity, etc.).
The Digital Motor Electronics (DME) diagnosis the voltage at the Accelerator Pedal Module Pedal Sensor 2. The Diagnostic Trouble Code (DTC) is detected when there is a short circuit to ground.
