HELPFUL INFORMATION
Circuit A142 splices to supply voltage to the fuel
injectors, ignition coil, ASD relay, generator, and the
upstream and downstream (2.5L only) 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 (2.0L and 2.4L)
Circuit A14 is connected to the 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 cir-
cuit A142. A 20 amp fuse, in cavity 5 of the PDC, pro-
tects 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.
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.
•
Circuit K17 is the ground circuit for the ignition
coil that fires spark plugs #1 and #4. Circuit K17
connects to cavity 3 of the PCM.
•
Circuit K19 is the ground circuit for the ignition
coil that fires spark plugs #2 and #3. Circuit K19
connects to cavity 2 of the PCM.
HELPFUL INFORMATION
Circuit A142 splices to supply voltage to the fuel
injectors, ASD relay, generator, and the upstream
and downstream (2.5L) heated oxygen sensors. The
PCM controls the ground circuit for each of the com-
ponents powered by circuit A142.
DISTRIBUTOR (2.5L)
The 2.5L V-6 engine uses a distributor. The distrib-
utor is used for firing the spark plugs and for provid-
ing
camshaft
position
input
to
the
Powertrain
Control Module (PCM). Circuit K44 is used to indi-
cate to the PCM camshaft position and connects to
cavity 33 of the PCM. Circuit K4 is used for the sen-
sor return to the PCM and connects to cavity 43.
The K19 circuit is an output from the PCM to the
distributor and is used for the coil driver. Grounding
for the distributor is provided at the cylinder head
ground.
Battery voltage for the distributor is provided from
two sources, circuits A142 and K7. The K7 circuit is
the 8 volt output from the PCM. Circuit A142 is HOT
when the contacts in the ASD relay are CLOSED.
HELPFUL INFORMATION
•
Refer to group 14 for system operation.
IDLE AIR CONTROL MOTOR
The Powertrain Control Module (PCM) operates
the idle air control motor through 4 circuits - K39,
K40, K59, and K60. Each circuit connects to separate
cavities in the PCM connector.
•
Circuit K39 connects to cavity 57 of the PCM
connector
•
Circuit K40 connects to cavity 48 of the PCM
connector
•
Circuit K59 connects to cavity 58 of the PCM
connector
•
Circuit K60 connects to cavity 49 of the PCM
connector
HELPFUL INFORMATION
•
Refer to group 14 of the Service Manual or the
appropriate Diagnostic Test Procedures Manual for
additional information.
POWER STEERING PRESSURE SWITCH
The power steering pressure switch opens and
closes circuit K10 between the Powertrain Control
Module (PCM) and ground. Circuit K10 connects to
cavity 45 of the PCM connector.
Circuit Z1 provides a ground for the power steering
pressure switch. The ground is terminated at the
Body Control Module (BCM).
DUTY CYCLE EVAP/PURGE SOLENOID
Circuit F18 supplies battery voltage to the duty
cycle EVAP/Purge solenoid. This circuit is HOT in
the START and RUN position only. It is also spliced
and provides power for the Anti-Lock warning lamp,
A/C clutch relay, and high speed radiator fan relay.
Circuit F18 connects to the PDC, cavity 9, and is
protected by a 10 amp fuse. Power for the fuse is
supplied on circuit A21 from the ignition switch. Cir-
cuit A1 provides power for the A21 circuit and is pro-
tected by a 20 amp fuse located in cavity 8 of the
Power Distribution Center (PDC).
The Powertrain Control Module (PCM) controls the
ground path for the solenoid on circuit K52. Circuit
K52 connects to cavity 68 of the PCM connector.
HELPFUL INFORMATION
•
Refer to group 14 and group 25, for system oper-
ation
•
Check the 10 amp fuse located in cavity 9 of the
PDC.
•
Check the 20 amp fuse located in cavity 8 of the
PDC
