Q: What does code P2C80 mean?

AIR System Pump Overspeed Bank 1. P2C80 indicates that the powertrain control module has detected the secondary air injection pump for bank 1 spinning faster than the commanded or expected speed, which usually points to a control or feedback fault rather than a mechanical pump failure. The computer compares commanded pump operation with feedback from the pump circuit or speed sensor and sets this code when the overspeed condition persists beyond a calibrated threshold.
