1997 DODGE NEON Crank

Downloaded from www.Manualslib.com manuals search engine The PCM provides ground for the knock sensor sig-
nal (circuit K42) through circuit K4. Circuit K4 con-
nects to cavity 43 of the PCM connector.
HELPFUL INFORMATION
Circuit K4 splices to supply ground for the signals
from the following:
²Upstream heated oxygen sensor
²Downstream heated oxygen sensor
²Battery temperature sensor
²Camshaft position sensor
²Crankshaft position sensor
²Engine coolant temperature sensor
²Throttle position sensor
²Intake air temperature sensor
²Manifold absolute pressure sensor
²Vehicle speed sensor
BATTERY TEMPERATURE SENSOR
From circuit G31 the battery temperature sensor
draws voltage from the Powertrain Control Module
(PCM). The sensor is a variable resistor. As battery
temperature changes, the resistance in the sensor
changes causing a change in current draw. Circuit
G31 connects to cavity 52 of the PCM connector.
The PCM provides ground for the battery tempera-
ture sensor signal (circuit G31) through circuit K4. Cir-
cuit K4 connects to cavity 43 of the PCM connector.

FUEL INJECTORS
Circuit A14 is a bus bar in the Power Distribution
Center (PDC), and connects to battery voltage. The
contact side of the Automatic Shut Down (ASD) relay
connects circuit A14 and circuit A142. A 20 amp fuse
in the PDC protects circuits A14 and A142.
Circuit A14 also supplies voltage to the coil side of
the ASD relay. The Powertrain Control Module
(PCM) controls the ground circuit for the coil side of
the ASD relay on circuit K51. Circuit K51 connects to
cavity 67 of the PCM connector.
Circuit A142 supplies voltage for the fuel injectors.
The PCM controls the ground circuit of each injector.²Circuit K11 is the ground circuit for Injector #1.
Circuit K11 connects to cavity 13 of the PCM.
²Circuit K12 is the ground circuit for Injector #2.
Circuit K12 connects to cavity 17 of the PCM.
²Circuit K13 is the ground circuit for Injector #3.
Circuit K13 connects to cavity 7 of the PCM.
²Circuit K14 is the ground circuit for Injector #4.
Circuit K14 connects to cavity 16 of the PCM.
HELPFUL INFORMATION
Circuit A142 splices to supply voltage to the fuel
injectors, ignition coil, ASD relay, generator, and the
upstream and downstream heated oxygen sensors.
The PCM controls the ground circuit for each of the
components powered by circuit A142.
The injectors operate in sequence. Refer to Group
14 for system operation.
IGNITION COIL PACK
Circuit A14 is a bus bar in the Power Distribution
Center (PDC), and connects to battery voltage. The
contact side of the Automatic Shut Down (ASD) relay
connects circuit A14 and circuit A142. A 20 amp fuse
in the PDC protects circuits A14 and A142.
Circuit A14 also supplies voltage to the coil side of
the ASD relay. The Powertrain Control Module
(PCM) controls the ground path circuit for the coil
side of the ASD relay on circuit K51. Circuit K51 con-
nects to cavity 67 of the PCM connector.
Circuit A142 supplies voltage for the ignition coil
pack. The coil pack consists of two individual coils
molded together. The PCM controls the ground cir-
cuit of each coil.
²Circuit K19 is the ground circuit for the ignition
coil that fires spark plugs # 1 and # 4. Circuit K19
connects to cavity 2 of the PCM.
²Circuit K17 is the ground circuit for the ignition
coil that fires spark plugs #2 and # 3. Circuit K17
connects to cavity 3 of the PCM.
HELPFUL INFORMATION
Circuit A142 splices to supply voltage to the fuel
injectors, ignition coil, ASD relay, generator, upstream
heated oxygen sensor and downstream heated oxygen
sensor. The PCM controls the ground circuit for each of
the components powered by circuit A142.
IDLE AIR CONTROL MOTOR
The Powertrain Control Module (PCM) operates
the Idle Air Control (IAC) motor through 4 circuits -
K39, K40, K59, and K60. Each circuit connects to
separate cavities in the PCM connector.
²Circuit K39 connects to cavity 57 of the PCM
connector.
²Circuit K40 connects to cavity 48 of the PCM
connector.
