DESCRIPTION AND OPERATION (Continued)
• Circuit K59 connects to cavity 58 of the PCM
connector.
• Circuit K60 connects to cavity 49 of the PCM
connector.

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 Z12 provides ground for the power steering
pressure switch. The grounding point for circuit Z12
is the left side of the radiator closure panel.

TORQUE CONVERTER CLUTCH SOLENOID (TCC)

The Powertrain Control Module (PCM) operates
the TCC solenoid by providing a ground path on cir-
cuit K54. Circuit K54 connects to PCM cavity 79.
Circuit F12 supplies battery voltage to the TCC
solenoid. Circuit F12 connects to a bus bar in the
fuse block fed by circuit A21. A 15 amp fuse in the
fuse block, cavity 10, protects circuit F12. Circuit F12
connects to cavity 20 of the PCM connector.
HELPFUL INFORMATION
Circuit F12 splices to feed the ABS control module,
PCM, EGR solenoid, leak detection pump, and the
duty cycle EVAP/Purge solenoid. The F12 circuit also
connects to a bus bar in the PDC that supplies volt-
age to the coil side of radiator fan relay, A/C clutch
relay, and fuel pump relay.
In the RUN or START position, the ignition switch
connects circuit A1 from the fuse block and circuit
A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.

DUTY CYCLE EVAP/PURGE SOLENOID

Circuit F12 supplies battery voltage to the Duty
Cycle EVAP/Purge solenoid. The Powertrain Control
Module (PCM) switches ground path for the solenoid
ON and OFF through circuit K52.
Circuit F12 connects to a bus bar in the fuse block
fed by circuit A21. A 15 amp fuse in the fuse block,
cavity 10, protects circuit F12. Circuit F12 also con-
nects to cavity 20 of the PCM connector.
Circuit K52 connects to cavity 68 of the PCM, and
cavity 1 of the solenoid connector.
HELPFUL INFORMATION
Circuit F12 splices to feed the ABS control module,
PCM, EET solenoid, leak detection pump, and the
TCC solenoid. The F12 circuit also connects to a bus
bar in the PDC that supplies voltage to the coil side
of radiator fan relays, A/C clutch relay, and fuel
pump relay.
In the START or RUN position, the ignition switch
connects circuit A1 from the fuse block and circuit
8W - 30 FUEL/IGNITION SYSTEMS
A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.

EGR TRANSDUCER (EET) SOLENOID

Circuit F12 supplies battery voltage to the EET
solenoid. The Powertrain Control Module (PCM)
switches ground path for the solenoid ON and OFF
through circuit K35.
Circuit F12 connects to a bus bar in the fuse block
fed by circuit A21. A 15 amp fuse in the fuse block,
cavity 10, protects circuit F12. Circuit F12 also con-
nects to cavity 20 of the PCM.
Circuit K35 connects to cavity 40 of the PCM con-
nector.
HELPFUL INFORMATION
Circuit F12 splices to feed the ABS control module,
PCM, Duty Cycle EVAP/Purge solenoid, leak detec-
tion pump, and the TCC solenoid. The F12 circuit
also connects to a bus bar in the PDC that supplies
voltage to the coil side of radiator fan relays, A/C
clutch relay, and fuel pump relay.
In the START or RUN position, the ignition switch
connects circuit A1 from the fuse block and circuit
A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.
LOW FUEL DETECT INPUT
Circuit G4 provides an input to the Powertrain Con-
trol Module (PCM) indicating fuel tank level. This cir-
cuit connects to cavity 23 of the PCM connector.
The G4 circuit is also used for the fuel gauge
located in the instrument cluster. For operation of
the fuel gauge, refer to section 8W-40.
PARK/NEUTRAL POSITION SWITCH INPUT (3–SPD
TRANSMISSION)
On vehicles equipped with the 3–spd automatic
transmission the park/neutral switch provides an
input to the Powertrain Control Module (PCM).
When CLOSED, the park/neutral position switch
provides a ground path on circuit T41 for the coil
side of the engine starter motor relay. The case
grounded switch provides ground for circuit T41.
Circuit A41 from the ignition switch provides bat-
tery voltage to the coil side of the relay.
Circuit T41 splices to cavity 76 of the PCM. The
park/neutral position switch provides an input to the
Powertrain Control Module (PCM).
HELPFUL INFORMATION
In the START position, the ignition switch connects
circuit A1 from the Power Distribution Center (PDC)
to circuit A41. A 30 amp fuse protects circuits A1 and
A41.
