Q: What does code P2CB6 mean?

Turbocharger/Supercharger Boost System Performance. P2CB6 is a generic powertrain code indicating that the engine control module (ECM) has detected a performance problem with the turbocharger or supercharger boost system, meaning the actual boost pressure does not match the commanded boost pressure under specific operating conditions. The ECM monitors boost pressure via a sensor and compares it to a desired value calculated from airflow, throttle position, and engine speed, then sets this code when the discrepancy exceeds a calibrated threshold for a set time.
