Turbocharger Boost Control Position Sensor A Circuit
General electrical fault on the turbocharger boost control position sensor A — the feedback sensor on the wastegate or VGT actuator (often a contactless Hall sensor). Without valid position feedback the ECM cannot close the loop on boost control and falls back to open-loop duty cycle.
