Q: What does code P2CAD mean?

Charge Air Cooler Coolant Pump B Control Circuit/Open. P2CAD indicates that the powertrain control module (PCM) has detected an open circuit or control fault on the electrical path for the charge air cooler coolant pump B, which is the auxiliary pump that circulates coolant through the air-to-liquid intercooler to cool the intake charge. The PCM monitors the pump's control circuit for expected voltage or current feedback and sets this code when the signal is missing or out of range, meaning the pump is not being commanded or is not responding as designed.
