What does code P2B67 mean?

Q: What does code P2B67 mean?

Coolant Pump D Control Circuit Low. P2B67 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for coolant pump D, which is an auxiliary electric pump used for charge-air cooling or battery thermal management. The PCM commands the pump on and monitors the circuit, and when the voltage on the control side stays below the expected threshold, it sets this code.
