Crankshaft Position Sensor: Description and Operation
Crankshaft Position (CKP) Sensor
The Crankshaft Position (CKP) Sensor is used to signal the ECM when a spark and/or fuel injection event required. The output from this sensor, in
conjunction with the Camshaft Position Sensor signal, is used to determine whether spark or fuel is required in a particular cylinder. The engine will not
start without a CKP Sensor signal to the ECM.
