Regal V6-3.8L VIN K (1997)
magnetic field will cause the CKP Sync Hall effect switch to ground the CKP Sync signal voltage supplied from the ignition control module. The CKP
18X interrupter ring and Hall-effect switch react similarly. The ignition control module interprets the CKP 18X and CKP Sync ON - OFF signals as an
indication of crankshaft position, and the ignition control module must have both signals to fire the correct ignition coil.
The ignition control module determines crankshaft position for correct ignition coil sequencing by counting how many CKP 18X signal transitions occur,
i.e.; ON - OFF or OFF - ON, during a CKP Sync pulse.
