What does code P2CAE mean?

Q: What does code P2CAE mean?

Charge Air Cooler Coolant Pump B Control Circuit Low. P2CAE indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the charge air cooler coolant pump B. This pump circulates coolant through the air-to-liquid intercooler to cool the compressed intake air, and the low circuit voltage suggests a short to ground, an open circuit, or a faulty pump.
