Crankcase Pressure Sensor
WARNING: This page is about a different car, the 2022 Ford Police Interceptor Utility and 2022 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The crankcase pressure sensor measures the vacuum in the PCV system. A change in the PCV system vacuum greater than a calibrated threshold indicates the PCV system is disconnected and will set a DTC. The crankcase pressure sensor is located in the PCV system hose between the intake air system air cleaner and the engine crankcase PCV inlet.
The CKCP has one output from the sensor. There is one reference voltage circuit and one signal return circuit for the sensor.
