4.7L V-8
The Crankshaft Position (CKP) sensor (1) is mounted
into the right rear side of the cylinder block. It is posi-
tioned and bolted into a machined hole.
OPERATION
3.7L V-6
Engine speed and crankshaft position are provided
through the CKP (Crankshaft Position) sensor. The
sensor generates pulses that are the input sent to the
Powertrain Control Module (PCM). The PCM interprets
the sensor input to determine the crankshaft position.
The PCM then uses this position, along with other
inputs, to determine injector sequence and ignition
timing.
The sensor (3) is a hall effect device combined with
an internal magnet. It is also sensitive to steel within a
certain distance from it.
A tonewheel (targetwheel) is bolted to the engine
crankshaft (1). This tonewheel has sets of notches (2)
at its outer edge.
The notches cause a pulse to be generated when they
pass under the sensor. The pulses are the input to the
PCM.
