Crankshaft Position Sensor: Description and Operation
2000 All (Except diesel/Propane/Villager)
Crankshaft Position Sensor (Integrated Ignition Systems)
Three Different Types Of Crankshaft Position (CKP) Sensors
The Crankshaft Position (CKP) sensor is a magnetic transducer mounted on the engine block adjacent to a pulse wheel located on the crankshaft. By
monitoring the crankshaft mounted pulse wheel, the CKP is the primary sensor for ignition information to the Powertrain Control Module (PCM). The
trigger wheel has a total of 35 teeth spaced 10 degrees apart with one empty space for a missing tooth. The 6.8L ten cylinder pulse wheel has 39 teeth
spaced 9 degrees apart and one 9 degree empty space for a missing tooth. By monitoring the trigger wheel, the CKP indicates crankshaft position and
speed information to the PCM. By monitoring the missing tooth, the CKP is also able to identify piston travel in order to synchronize the ignition
system and provide a way of tracking the angular position of the crankshaft relative to fixed reference.
