DISTRIBUTOR PULSE RING
14 - 30 FUEL SYSTEM
DESCRIPTION AND OPERATION (Continued)
2.5L ENGINE
The 2.5L engine is equipped with a camshaft
driven mechanical distributor. The distributor is also
equipped with an internal camshaft position (fuel
sync) sensor (Fig. 3).
Fig. 3 Camshaft Position Sensor—2.5L
CRANKSHAFT POSITION SENSOR—PCM INPUT
The PCM determines what cylinder to fire from the
crankshaft and camshaft position sensor input. It is
also used to synchronize the fuel injectors with their
respective cylinders.
Refer to Group 8D - Crankshaft Position Sensor for
more information.
2.4L ENGINES
On 2.4L engines, the second crankshaft counter- MACHINED NOTCHES
weight has two sets of four timing reference notches
including a 60 degree signature notch (Fig. 4). From
the crankshaft position sensor input the PCM deter-
mines engine speed and crankshaft angle (position).
SYNC GENERATOR SIGNAL
The crankshaft position sensor mounts to the
engine block behind the generator, just above the oil
filter (Fig. 5).

2.5L ENGINE
On a 2.5L engine, this sensor is a hall effect device
that detects notches in the flexplate.
The sensor is located in the transaxle housing,
above the vehicle speed sensor (Fig. 6).
ENGINE COOLANT TEMPERATURE SENSOR—PCM
INPUT
The coolant temperature sensor has one element.
The element supplies coolant temperature signal to
the PCM. The PCM supplies coolant temperature
information on the CCD Bus to the Body Control
Module (BCM) for the instrument panel gauge clus-
ter. The PCM determines engine coolant temperature
from the coolant temperature sensor.
