Crankshaft Position Sensor/Crank Angle Sensor

Print

OPERATION



The Crankshaft Position (CKP) sensor (also referred to as the crank angle sensor) senses the crank angle (piston position) of each cylinder and converts it into a pulse signal. The PCM receives this signal and then computes the engine speed ad controls the fuel injector timing and ignition timing based on this input.

TESTING



This sensor produces a pulse signal based on information gathered while the engine is running. Testing the CKP sensor requires several special tools that are very expensive to purchase. Due to this fact, we have determined testing this sensor to be beyond the scope of the do-it-yourself mechanic. The sensor can be monitored with an appropriate scan tool using a data display or other data stream information. Follow the instructions included with the scan tool for information on accessing the data.
