P2599 Turbocharger Boost Control Position Sensor A Performance - Stuck High
Position sensor A reports a value stuck near the high end of its travel — actuator stuck open (wastegate held wide open, VGT vanes seized at maximum opening) or sensor pegged high. Boost suffers — typically underboost on VGT, overboost-protection-off on wastegate.
