Charge Air Cooler Temperature (CACT) Sensor
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2019 Lincoln Navigator, 2019 Lincoln Nautilus, 2019 Lincoln MKZ, 2019 Lincoln MKT, and 2019 Lincoln MKC. 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.
