CRANKSHAFT POSITION (CKP) SENSOR CONSTRUCTION/OPERATION [MZI-3.7]

• By monitoring the crankshaft mounted pulse wheel, the CKP is the primary sensor for ignition information to the PCM.
• By monitoring the pulse wheel, the CKP sensor signal indicates the crankshaft position and speed information to the PCM. By monitoring the missing tooth, the CKP sensor 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 a fixed reference for the CKP sensor configuration.
• The PCM also uses the CKP signal to determine if a misfire has occurred by measuring rapid decelerations between teeth.
