Sensor, Boost Pressure: Operation: Operation

The Boost Pressure Sensor operates as a typical three wire sensor. It is used to measure the pressure of the air entering the Turbocharger. It receives a 5-Volt feed on the (K668) Boost Pressure Sensor 5-Volt Supply circuit and shares the (K690) ground circuit with the Intake Air Temperature Sensor. The Powertrain Control Module (PCM) receives a signal from the sensor via the (K37) Boost Pressure Sensor Signal circuit.
