GENERAL INFORMATION
INTRODUCTION
Service and maintenance procedures for compo-
nents and systems listed in Schedule ± A or B can be
found by using the Group Tab Locator index at the
front of this manual. If it is not clear which group
contains the information needed, refer to the index at
the back of this manual.
There are two maintenance schedules that show
proper service based on the conditions that the vehi-
cle is subjected to.
Schedule ±A, lists scheduled maintenance to be
performed when the vehicle is used for general trans-
portation.
Schedule ±B, lists maintenance intervals for vehi-
cles that are operated under the conditions listed at
the beginning of the Maintenance Schedule section.
Use the schedule that best describes your driving
conditions.
Where time and mileage are listed, follow the
interval that occurs first.

engine is operating, the smaller the pulse width on
the oscilloscope.
By counting the pulses and referencing the pulse
from the 60 degree signature notch, the PCM calcu-
lates crankshaft angle (position). In each group of
timing reference notches, the first notch represents
69 degrees before top dead center (BTDC). The sec-
ond notch represents 49 degrees BTDC. The third
notch represents 29 degrees. The last notch in each
set represents 9 degrees before top dead center
(TDC).
The timing reference notches are machined to a
uniform width representing 13.6 degrees of crank-
shaft rotation. From the voltage pulse width the
PCM tells the difference between the timing refer-
ence notches and the 60 degree signature notch. The
60 degree signature notch produces a longer pulse
width than the smaller timing reference notches. If
the camshaft position sensor input switches from
high to low when the 60 degree signature notch
passes under the crankshaft position sensor, the
PCM knows cylinder number one is the next cylinder
at TDC.
The crankshaft position sensor mounts to the
engine block behind the generator, near the oil filter
(Fig. 8).
CAMSHAFT POSITION SENSOR
The PCM determines fuel injection synchronization
and cylinder identification from inputs provided by
the camshaft position sensor and crankshaft position
sensor. From the two inputs, the PCM determines
crankshaft position.The camshaft position sensor attaches to the rear
of the cylinder head (Fig. 2). A target magnet
attaches to the rear of the camshaft and indexes to
the correct position (Fig. 3). The target magnet has
four different poles arranged in an asymmetrical pat-
tern. As the target magnet rotates, the camshaft
position sensor senses the change in polarity (Fig. 4).
The sensor output switch switches from high (5.0
volts) to low (0.30 volts) as the target magnet rotates.
When the north pole of the target magnet passes
under the sensor, the output switches high. The sen-
sor output switches low when the south pole of the
target magnet passes underneath.
INTAKE AIR TEMPERATURE SENSORÐ2.4L
The intake air temperature sensor measures the
temperature of the air as it enters the engine. The
sensor supplies one of the inputs the PCM uses to
determine injector pulse width and spark advance.
The intake air temperature sensor threads into the
intake manifold (Fig. 5).

DESCRIPTION AND OPERATION (Continued)

CRANKSHAFT POSITION SENSOR
The crankshaft position sensor mounts to the
engine block behind the generator, just behind the oil
filter (Fig. 8).
REMOVAL
(1) Raise and support vehicle.
(2) Disconnect electrical connector from crankshaft
position sensor.
(3) Remove sensor mounting screw.
(4) Pull crankshaft position sensor straight out.
INSTALLATION
NOTE: If the removed sensor is to be reinstalled,
clean off the old spacer on the sensor face. A NEW
SPACER must be attached to the sensor face before
installation. If the sensor is being replaced, confirm
that the paper spacer is attached to the face of the
new sensor.
(1) Install sensor and push sensor down until con-
tact is made. While holding the sensor in this posi-
tion, and install and tighten the retaining bolt to 11.9
N´m (105 in. lbs.) torque.
CAMSHAFT POSITION SENSOR
The camshaft position sensor is mounted to the
rear of the cylinder head (Fig. 9).
REMOVAL
(1) Disconnect the filtered air tube from the throt-
tle body and air cleaner housing. Disconnect the airtube from the oil separator hose. Remove filtered air
tube.
(2) Remove the air cleaner inlet tube.
(3) Disconnect engine harness connector from cam-
shaft position sensor.
(4) Remove camshaft position sensor mounting
screws. Remove sensor.
(5) Loosen screw attaching target magnet to rear
of camshaft (Fig. 10).
INSTALLATION
The target magnet has locating dowels that fit into
off-set machined locating holes in end of the cam-
shaft (Fig. 11).
