Code P1222 MINI Description

The P1222 MINI diagnostic trouble code indicates that there is a low input signal coming from Pedal Position Sensor 2. This sensor is responsible for monitoring the position of the accelerator pedal and sending this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing to optimize engine performance. When the sensor detects a low input signal, it means that the voltage being sent to the ECM is lower than expected, which can lead to various performance issues.
