|What Does the P0123 MINI Code Mean?

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 Diagnostic Trouble Code (DTC) is detected when the voltage of the throttle valve sensor (1) exceeds the upper limit. Upper limit: 4.75 V.
