Camshaft Position (CMP) Sensor
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, 2016 Ford Transit-150, and 2016 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The CMP sensor is a Hall effect sensor that detects the position of the camshaft. The CMP sensor identifies when piston number 1 is on its compression stroke. The PCM calculates the CMP signal and the crankshaft position (CKP) sensor signal to determine the camshaft to crankshaft position for correct fuel injection timing during the compression stroke. The CMP sensor is located on the left side rear of the cylinder head (Transit). The CMP sensor is mounted at the front of the engine block, above the crankshaft pulley (All others).
