What does code P2B62 mean?

Q: What does code P2B62 mean?

Coolant Pump B Supply Voltage Circuit. P2B62 indicates that the powertrain control module has detected an abnormal voltage condition on the supply circuit for coolant pump B, which is often an auxiliary electric pump used for turbocharger or battery cooling. The computer monitors the voltage feed to the pump and sets this code when the signal falls outside the expected range, typically indicating an open circuit, short to ground, or high resistance in the wiring or pump itself.
