What Does a Boost Sensor Do?

Boost pressure sensors are used in turbocharged engines to provide air pressure information and air and fuel ratios in order to regulate engine performance. As a complex piece of technology, a boost pressure sensor has been an impressive addition to engine technology. Boost pressure sensors control the boost level produced in the intake manifold of a turbocharged or supercharged engine. They affect the air pressure delivered to the pneumatic and mechanical wastegate actuator.
