2000 DODGE NEON Service Repair Manual

IGNITION INTERLOCK
OPERATION
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 the - Tran-
saxle for Automatic Transmission Shifter/Ignition
Interlock.
REMOVAL AND INSTALLATION
SPARK PLUG SERVICE
Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.
REMOVAL
REMOVE CABLES FROM COIL FIRST.
Always remove the spark plug cable by grasping
the top of the spark plug insulator, turning the boot
1/2 turn and pulling straight up in a steady motion.
(1) Remove the spark plug using a quality socket
with a rubber or foam insert.
(2) Inspect the spark plug condition.
INSTALLATION
(1) To avoid cross threading, start the spark plug
into the cylinder head by hand.
(2) Tighten spark plugs to 28 N´m (20 ft. lbs.)
torque.
(3) Install spark plug insulators over spark plugs.
Ensure the top of the spark plug insulator covers the
upper end of the spark plug tube.
Reconnect to coil.
SPARK PLUG CABLE SERVICE
Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.
REMOVAL
Remove spark plug cable from coil first.
Always remove the spark plug cable by grasping
the top of the spark plug insulator, turning the boot
1/2 turn and pulling straight up in a steady motion.
INSTALLATION
Install spark plug insulators over spark plugs.
Ensure the top of the spark plug insulator covers the
upper end of the spark plug tube. The connect theother end to coil pack. Be sure that dual plastic clip
holds the cables off of the valve cover.
IGNITION COIL
The electronic ignition coil pack attaches directly
to the valve cover (Fig. 11).
REMOVAL
(1) Disconnect electrical connector from coil pack
(Fig. 10).
(2) Remove coil pack mounting bolts.
(3) Remove coil pack.
INSTALLATION
(1) Install coil pack on valve cover.
(2) Transfer spark plug cables to new coil pack.
The coil pack towers are numbered with the cylinder
identification. Be sure the ignition cables snap onto
the towers.
AUTOMATIC SHUTDOWN RELAY
The relay is located in the Power Distribution Cen-
ter (PDC) (Fig. 12). The PDC is located next to the
battery in the engine compartment. For the location
of the relay within the PDC, refer to the PDC cover
for location. Check electrical terminals for corrosion
and repair as necessary.
CAMSHAFT POSITION SENSOR
The camshaft position sensor is mounted to the
rear of the cylinder head (Fig. 13).

CRANKSHAFT POSITION SENSOR
The crankshaft position sensor mounts to the
engine block behind the generator, just above the oil
filter (Fig. 15).
REMOVAL
(1) Disconnect electrical connector from crankshaft
position sensor.
(2) Remove sensor mounting screw. Remove sensor.
INSTALLATION
(1) Install sensor. Install sensor mounting screw
and tighten.
(2) Connect electrical connector to crankshaft posi-
tion sensor.
KNOCK SENSOR
The knock sensor threads into the side of the cyl-
inder block in front of the starter (Fig. 16).
REMOVAL
(1) Disconnect electrical connector from knock sen-
sor.
(2) Use a crow foot socket to remove the knock
sensors.
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.
IGNITION SWITCH
The ignition switch attaches to the lock cylinder
housing on the end opposite the lock cylinder (Fig.
17). For ignition switch terminal and circuit identifi-
cation, refer to the Wiring Diagrams sections.

(1) Ensure the ignition switch is in the RUN posi-
tion and the actuator shaft in the lock housing is in
the RUN position.
(2) Carefully install the ignition switch. The
switch will snap over the retaining tabs (Fig. 21).
Install mounting screw (Fig. 19).(3) Install electrical connectors to ignition switch.
(4) Install upper and lower shrouds.
(5) Install key cylinder (cylinder retaining tab will
depress only in the RUN position).
(6) Connect negative cable to battery.
(7) Check for proper operation of ignition switch
and key-in warning switch.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 detentes (Fig. 22) :

GENERAL INFORMATION
INTRODUCTION
The purpose of the dash gauges and indicator
lamps is to keep the driver informed about the oper-
ating condition of the vehicle. If an abnormal condi-
tion occurs, the driver is informed by indicator lamp.
The driver can seek service before damage occurs.
Indicator lamps use ON/OFF switch functions for
operation, while gauges use a sending unit or sensor.
The Instrument Panel can be removed as an
assembly after a few part are removed to allow
access to the retaining bolts. There is one self-align-
ing bulkhead connector on the left underside of the
instrument panel replacing most of the main harness
connectors. Once removed, the instrument panel can
be serviced for replacement. Most of the parts of the
instrument panel can be replaced individually with-
out removing the complete instrument panel assem-
bly.
