Turbocharger Boost Pressure (TCBP) Sensor

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

The TCBP sensor is located in the intake air tube between the turbocharger and the charge air cooler (CAC). The TCBP sensor measures the throttle inlet pressure. The PCM uses the information from the TCBP sensor to refine the estimate of the airflow rate through the throttle and to determine the desired boost pressure. The TCBP sensor may be integrated with a charge air cooler temperature (CACT) sensor.

On some vehicles, the TCBP sensor or TCBP/CACT sensor has one digital signal output from the sensor. There is one reference voltage circuit and one signal return circuit for the sensor. For all others, the TCBP has one analog signal output from the sensor. The TCBP/CACT has two analog signal outputs from the sensor. There is one reference voltage circuit and one signal return circuit for the sensor.
