What does code P2CBE mean?

Q: What does code P2CBE mean?

PCV Heater "B" Control Circuit High. P2CBE indicates that the powertrain control module has detected an abnormally high voltage on the control circuit for the positive crankcase ventilation heater, which is a small electric heating element built into the PCV valve or its hose assembly. The high voltage condition tells the module that the circuit is likely open, shorted to voltage, or that the heater element itself has failed in a way that prevents normal current flow.
