The wastegate vacuum sensor is an absolute pressure sensor that provides the PCM an analog voltage output that is proportional to the applied vacuum. The wastegate vacuum sensor is located near the turbocharger and the turbocharger wastegate regulating valve solenoid. The wastegate vacuum sensor measures the vacuum supplied by the turbocharger wastegate regulating valve solenoid to the wastegate actuator. The PCM uses the information from the wastegate vacuum sensor to determine the amount of vacuum being applied to the wastegate actuator.
