Turbo Boost Sensor: Description and Operation
Boost Pressure Sensor
The boost pressure sensor is located in the air induction tubing. The boost pressure sensor is a transducer that varies voltage according to charges in the
air pressure inside the tubing. The generated voltage is input to the engine control module (ECM) for the boost sensor signal. The ECM should detect a
low signal voltage at a low boost pressure, such as low engine load. The ECM should detect high signal voltage at a high boost pressure, such as high
engine load.
