1996 CHRYSLER VOYAGER Service Manual

While holding the sensor in this position, and install
and tighten the retaining bolt to 11.9 N´m (105 in.
lbs.) torque.
(2) Raise and support vehicle.
(3) Connect crankshaft position sensor electrical
connector to the wiring harness connector.
CAMSHAFT POSITION SENSOR
REMOVAL
(1) Disconnect camshaft position sensor electrical
connector from the wiring harness connector (Fig. 5).
(2) Remove bolt holding sensor (Fig. 6).There is a
hole in the bracket for tool access to the sensor
bolt.
(3) Rotate sensor away from block (Fig. 7).
(4) Pull sensor up out of the chain case cover.Do
not pull on the sensor lead.There is an O-ring on
the sensor case. The O-ring may make removal diffi-
cult. A light tap to top of sensor prior to removal may
reduce force needed for removal.
INSTALLATION
If the removed sensor is reinstalled, clean off
the old spacer on the sensor face. A NEW
SPACER must be attached to the face beforeinstallation.Inspect O-ring for damage, replace if
necessary. If the sensor is being replaced, confirm
that the paper spacer is attached to the face and O-
ring is positioned in groove of the new sensor (Fig. 8).
(1) Apply a couple drops of clean engine oil to the
O-ring prior to installation.
(2) Install sensor in the chain case cover and
rotate into position.
(3) Push sensor down until contact is made with
the camshaft gear. While holding the sensor in this
position, install and tighten the retaining bolt 14
N´m (125 in. lbs.) torque.
(4) Connect camshaft position sensor electrical
connector to harness connector.

REMOVAL AND INSTALLATION (Continued)

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
REMOVAL
(1) Disconnect electrical connector from MAP sen-
sor.
(2) Remove 2 screws holding sensor to intake man-
ifold (Fig. 9).
(3) Remove sensor from manifold.
INSTALLATION
Reverse the above procedure for installation.
ENGINE COOLANT TEMPERATURE SENSOR
The Engine Coolant Temperature (ECT) sensor is
located below the ignition coil (Fig. 10).
REMOVAL
(1) Drain cooling system until coolant level is
below sensor. Refer to Group 7, Cooling System.
(2) Remove electrical connector from coil (Fig. 11).
(3) Remove coil mounting screws.
(4) Rotate coil away from engine coolant tempera-
ture sensor.
(5) Disconnect electrical connector from engine
coolant temperature sensor.
(6) Remove sensor from engine.
INSTALLATION
(1) Tighten the sensor to 7 N´m (60 in. lbs.) torque.
(2) Connect electrical connector to sensor.
(3) Fill cooling system. Refer to Group 7, Cooling
System.
(4) Install coil. Tighten coil mounting screws to 12
N´m (105 in. lbs.) torque.
(5) Connect electrical connector to coil.
THROTTLE POSITION SENSOR
Refer to Group 14, Fuel Injection Section, for
Removal/Installation.
KNOCK SENSORÐ3.3/3.8L
The knock sensor threads into the side of the cyl-
inder block in front of the starter (Fig. 12).

REMOVAL AND INSTALLATION (Continued)

REMOVAL
(1) Disconnect electrical connector from knock sen-
sor.
(2) Use a crow foot socket to remove the knock
sensor.
INSTALLATION
(1) Install knock sensor. Tighten knock sensor to
10 N´m (7 ft. lbs.) torque.Over or under tighten-
ing effects knock sensor performance, possibly
causing improper spark control.
(2) Attach electrical connector to knock sensor.

DESCRIPTION AND OPERATION
IGNITION INTERLOCK
All vehicles equipped with automatic transaxles
have an interlock system. The system prevents shift-
ing the vehicle out of Park unless the ignition lock
cylinder is in the Off, Run or Start position. In addi-
tion, the operator cannot rotate the key to the lock
position unless the shifter is in the park position. On
vehicles equipped with floor shift refer to Group 21 -
Transaxle for Automatic Transmission Shifter/Igni-
tion Interlock.
LOCK KEY CYLINDER
The lock cylinder is inserted in the end of the
housing opposite the ignition switch. The ignition key
rotates the cylinder to 5 different detents (Fig. 1):
²Accessory
²Off (lock)
²Unlock
²On/Run
²Start
REMOVAL AND INSTALLATION
IGNITION SWITCH
The ignition switch attaches to the lock cylinder
housing on the end opposite the lock cylinder (Fig. 2).
For ignition switch terminal and circuit identifica-
tion, refer to Group 8W, Wiring Diagrams.
