Boost Sensor

Boost sensor, used on turbo engines, monitors boost pressure and is used by PCM to open wastegate which limits pressure. At full load under WOT, boost sensor indicates high pressure (high voltage). At closed throttle under deceleration, boost sensor indicates low pressure (low voltage).
