Code P2122 MINI Description
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 1. The Diagnostic Trouble Code (DTC) is detected when there is a short circuit to ground.
What are the Possible Causes of the DTC P2122 MINI?
- Faulty Accelerator Pedal
- Accelerator Pedal harness is open or shorted
- Accelerator Pedal circuit poor electrical connection
- Faulty Accelerator Pedal Module
