P24C5EGR Cooler Bypass Position Sensor Exceeded Learning Limit Bank 2

P24C5 means the engine computer has learned that the bank 2 exhaust gas recirculation (EGR) cooler bypass valve position sensor no longer agrees with the commanded position within an acceptable range. The computer stores this code when the sensor's feedback during a self-test or normal operation falls outside the learned limits, indicating a mechanical or electrical fault in the bypass valve or its sensor circuit.
