DeVille DTS V8-4.6L VIN 9 (2002)
Crankshaft Position Sensor: Description and Operation
The Crankshaft Position (CKP) Sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic
pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the
sensor electronics to produce a digital output pulse. This system uses two sensors within the same housing for the V6 engine, and two separate sensors
for the V8 engine. The PCM supplies each sensor a 12-volt reference, low reference, and a signal circuit. The signal circuit returns a digital ON/OFF
pulse 24 times per crankshaft revolution.
