Charge Air Cooler Temperature (CACT) 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 CACT sensor is located in the intake air path between the charge air cooler (CAC) and the cylinder head. The CACT sensor measures the air temperature after the CAC. The CACT sensor may be integrated with a turbocharger boost pressure (TCBP) sensor or a manifold absolute pressure and temperature (MAPT) sensor.
