What does code P2AD5 mean?

Q: What does code P2AD5 mean?

Intermediate System Voltage High. P2AD5 indicates that the powertrain control module (PCM) has detected an intermediate system voltage that is higher than the expected range for the vehicle's electrical architecture. This intermediate voltage is typically a stepped-down supply used by certain control modules or sensors, and the PCM sets the code when the monitored circuit exceeds its calibrated upper limit.
