A boost pressure sensor (BPS) uses to monitor the boost pressure within the intake manifold. The powertrain control module (PCM) utilizes the information of the BPS sensor to determine the correct amount of fuel, measure the ideal ignition timing, and actuate the turbocharger wastegate.

The boost pressure sensor is most commonly located in the boost pipes between the turbocharger and the intake manifold. This sensor may also be placed in the intake manifold of some vehicles. In this area, the sensor may also record the boost pressure of your vehicle’s turbocharger or supercharger without anything interfering.

When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7V. Pressure range is between 10kPa and 350kPa. The sensor receives a 5V reference from the ECM. Sensor ground is also provides by the ECM. The ECM uses boost pressure combined with intake air temerature to determine the volume of air entering the engine.
