Circuit/System Description

The turbocharger vane position sensor is mounted on the turbo charger vacuum actuator. The engine control module (ECM) uses the turbocharger vane position sensor to determine the position of the turbocharger vanes. The ECM sends a reference voltage through the 5 V reference circuit to the position sensor. The ECM provides a voltage return path for the sensor through the low reference circuit. A variable voltage signal, based on the vane position, is sent from the sensor to the ECM through the position sensor signal circuit.
