P2599Turbocharger Boost Control Position Sensor A Performance - Stuck High

P2599 means the engine computer has detected that the turbocharger boost control position sensor on circuit A is reporting a stuck-high signal, meaning the sensor voltage remains above the expected range for the current operating conditions. The computer compares the commanded boost control position with the actual sensor feedback and flags the fault when the signal fails to move or stays pegged high.
