Crankcase Pressure Sensor
WARNING: This page is about a different car, the 2024 Ford Transit-350 HD, 2024 Ford Transit-350, 2024 Ford Transit-250, and 2024 Ford Transit-150. 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 has an analog signal output.
