CRANKSHAFT POSITION (CKP) SENSOR CONSTRUCTION/OPERATION [WL-C, WE-C]
id0140b7104800
• The CKP sensor is installed to the clutch housing.
• The pulse wheel which is installed to the dual-mass flywheel has 58 projections and spaces with 6° of crank angle between each projection.
• The fluctuation in magnetic flux density detected by the magnetic pickup coil in the crankshaft position sensor is input to the PCM as a sensor output signal.
• If the crankshaft position sensor is removed/installed or replaced, magnetized objects such as metal shavings adhering to the sensor could cause fluctuation in the magnetic flux of the magnetic pickup coil, causing abnormal sensor output which could adversely affect engine control.
