HEATED OXYGEN SENSORS
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 splices to supply voltage for the
upstream and downstream heated oxygen sensors.
The A142 circuit also splices to cavity 6 of the
PCM. The input provided by circuit A142 at cavity 6
tells the PCM that the ASD relay energized.
Circuit K41 delivers the signal from the upstream
heated oxygen sensor to the PCM. Circuit K41 con-
nects to cavity 30 of the PCM connector.
Circuit K141 delivers the signal from the down-
stream heated oxygen sensor to the PCM. Circuit
K141 connects to cavity 51 of the PCM connector.
The PCM provides a ground for the upstream and
downstream heated oxygen sensor signals (circuit
K41 and K141) through circuit K4. Circuit K4 con-
nects to cavity 43 of the PCM connector.
Circuit Z1 provides ground for the heater circuits
in each sensor. Circuit Z1 terminates at the left side
of the radiator closure panel.
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.
CRANKSHAFT POSITION SENSOR
Circuit K7 supplies 8 volts from the Powertrain
Control Module (PCM) to the crankshaft position
sensor. The K7 circuit connects to cavity 44 of the
PCM connector.
Circuit K24 from the sensor provides an input sig-
nal to the PCM. The K24 circuit connects to cavity 32
of the PCM connector.
The PCM provides ground for the crankshaft position
sensor signal (circuit K24) through circuit K4. Circuit
K4 connects to cavity 43 of the PCM connector.
HELPFUL INFORMATION
Circuit K7 splices to supply 8 volts to the camshaft
position sensor and vehicle speed sensor.
Circuit K4 splices to supply ground for the signals
from the following:
²Upstream heated oxygen sensor
²Downstream heated oxygen sensor
²Camshaft position sensor
²Battery temperature sensor
²Throttle position sensor
²Manifold absolute pressure sensor
²Engine coolant temperature sensor
²Knock sensor
²Intake air temperature sensor
²Vehicle speed sensor
CAMSHAFT POSITION SENSOR
Circuit K7 supplies 8 volts from the Powertrain
Control Module (PCM) to the camshaft position sen-
sor. The K7 circuit connects to cavity 44 of the PCM
connector.
Circuit K44 from the sensor provides an input sig-
nal to the PCM. The K44 circuit connects to cavity 33
of the PCM connector.
The PCM provides ground for the camshaft posi-
tion sensor signal (circuit K44) through circuit K4.
Circuit K4 connects to cavity 43 of the PCM connec-
tor.
HELPFUL INFORMATION
Circuit K7 splices to supply 8 volts to the camshaft
position sensor and vehicle speed sensor.
Circuit K4 splices to supply ground for the signals
from the following:
²Upstream heated oxygen sensor
²Downstream heated oxygen sensor
²Crankshaft position sensor
²Battery temperature sensor
²Throttle position sensor
²Manifold absolute pressure sensor
²Engine coolant temperature sensor
²Knock sensor
²Intake air temperature sensor
²Vehicle speed sensor
ENGINE COOLANT TEMPERATURE SENSOR
The engine coolant temperature sensor provides an
input to the Powertrain Control Module (PCM) on
circuit K2. The sensor also operates the engine cool-
ant temperature gauge in the instrument cluster on
circuit G20. Refer to Section 8W-40 for coolant tem-
perature gauge circuit description.
From circuit K2 the engine coolant temperature
sensor draws up to 5 volts from the PCM. The sensor
is a variable resistor. As coolant temperature
changes, the resistance in the sensor changes causing
