When installing a used camshaft position sensor,
the sensor depth must be adjusted to prevent contact
with the camshaft gear (sprocket).
(1) Observe the face of the sensor. If any of the
original rib material remains (Fig. 4), it must be cut
down flush to the face of the sensor with a razor
knife. Remove only enough of the rib material until
the face of the sensor is flat/Do not remove more
material than necessary as damage to sensor may re­
sult. Due to a high magnetic field and possible elec­
trical damage to the sensor, never use an electric
grinder to remove material from sensor.
(2) From the parts department, obtain a peel-and-
stick paper spacer (Fig. 4). These special paper spac­
ers are of a certain thickness and are to be used as a
tool to set sensor depth.
(3) Clean the face of sensor and apply paper spacer
(Fig.
4).
(4) Apply a small amount of engine oil to the sen­
sor o-ring (Fig. 5).
(5) Install the sensor into the timing case/cover
with a slight rocking action until the paper spacer
contacts the camshaft gear. Do not install the sensor
mounting bolt. Do not twist the sensor into position
as damage to the o-ring or tearing of the paper
spacer may result.
(6) Scratch a scribe line into the timing chain case/
cover to indicate depth of sensor (Fig. 5).
(7) Remove the sensor from timing chain case/
cover.
(8) Remove the paper spacer from the sensor. This
step must be followed to prevent the paper spacer
from getting into the engine lubrication system.
(9) Again, apply a small amount of engine oil to
sensor o-ring. ; , ,
(10) Again, install the sensor into the timing case/
cover with a slight rocking action until the sensor is
aligned to scribe line.
(11) Install sensor mounting bolt and tighten to 6
N*m (50 in. lbs.) torque.
(12) Connect engine wiring harness to sensor har­
ness.
SENSOR REPLACEMENT—NEW SENSOR
If a new replacement camshaft position sensor is to
be installed, use this procedure.
iEiOWAL
(1) Disconnect the sensor wiring harness connector
from the engine harness connector.
(2) Remove the sensor mounting bolt (Fig. 3).
(3) Carefully pry the sensor from the timing chain
case/cover in a rocking action with two small screw­
drivers.
(4) Remove the sensor from vehicle.
INSTALLATION
(1) Apply a small amount of engine oil to the sen­
sor o-ring (Fig. 5).
(2) Install the sensor into the timing case/cover
with a slight rocking action. Do not twist the sensor
into position as damage to the o-ring may result.
Push the sensor all the way into the cover until the
rib material on the sensor (Fig. 4) contacts the cam­
shaft gear.
(3) Install the mounting bolt and tighten to 6 N-m
(50 in.-lbs.) torque.
(4) Connect sensor wiring harness to engine har­
ness.
CRANKSHAFT POSITION SENSOR—3.9L V-6 OR
5.2/5.9L V-8 ENGINES
REMOVAL
The sensor is bolted to the top of the cylinder block
near the rear of right cylinder head (Fig. 6).

5.2/5.9L V-8 Engines—Typical
(1) Remove the air cleaner assembly and its plastic
air intake tube. Refer to the Component Removal/In­
stallation section for procedures.
(2) Remove the spark plug cable loom and spark
plug cables from valve cover mounting stud at rear of
right valve cover (Fig. 6). Position spark plug cables
to top of valve cover.
(3) Disconnect 2 hoses at Exhaust Gas Recircula­
tion (EGR) valve. Note position of hoses at EGR
valve before removal.
(4) Disconnect electrical connector and hoses at
electric EGR valve control. Note position of hoses be­
fore removal.
