DESCRIPTION AND OPERATION (Continued)
THROTTLE POSITION SENSOR
From the Powertrain Control Module (PCM), cir-
cuit K6 supplies 5 volts to the Throttle Position Sen-
sor (TPS). Circuit K6 connects to cavity 61 of the
PCM connector.
Circuit K22 delivers the TPS signal to the PCM.
Circuit K22 connects to cavity 35 of the PCM connec-
tor.
The PCM provides a ground path for the TPS sig-
nal (circuit K22) through circuit K4. Circuit K4 con-
nects to cavity 43 of the PCM connector.
HELPFUL INFORMATION
Refer to group 14 for throttle position sensor oper-
ation.
Circuit K6 is spliced and provides 5 volts to the
A/C pressure switch and the map sensor.
On automatic transmission vehicles, circuit K22 is
spliced and provides an input to the Transmission
Control Module (TCM).
Circuit K4 splices to supply ground for the signals
from the following:
• Intake air temperature sensor
• Camshaft position sensor
• Manifold absolute pressure sensor
• Ambient temperature sensor
• A/C pressure switch
• Crankshaft position sensor
• Vehicle speed sensor
• Heated oxygen sensors
MANIFOLD ABSOLUTE PRESSURE SENSOR
From the Powertrain Control Module (PCM), cir-
cuit K6 supplies 5 volts to the Manifold Absolute
Pressure (MAP) sensor. Circuit K6 connects to cavity
61 of the PCM connector.
Circuit K1 delivers the MAP signal to the PCM.
Circuit K1 connects to cavity 36 of the PCM connec-
tor.

nal (circuit K1) through circuit K4. Circuit K4 con-
nects to cavity 43 of the PCM connector.
HELPFUL INFORMATION
Refer to group 14 for MAP sensor operation.

8W - 30 FUEL/IGNITION SYSTEM
INTAKE AIR TEMPERATURE SENSOR
On the 2.0L engine the intake air temperature sen-
sor is combination unit with the map sensor.
The intake air temperature sensor provides an
input to the Powertrain Control Module (PCM) on
circuit K21. The K21 circuit connects to cavity 37 of
the PCM connector.
From circuit K21, the intake air temperature sen-
sor draws voltage from the PCM. The sensor is a
variable resistor. As intake air temperature changes,
the resistance in the sensor changes, causing a
change in current draw.
The PCM provides a ground path for the intake air
temperature sensor signal (circuit K21) through cir-
cuit K4. Circuit K4 connects to cavity 43 of the PCM
connector.
HELPFUL INFORMATION
Refer to group 14 for intake air temperature sensor
operation.
Circuit K4 splices to supply ground for the signals
from the following:
• Manifold absolute pressure sensor
• Camshaft position sensor
• Throttle position sensor
• Ambient temperature sensor
• A/C pressure switch
• Crankshaft position sensor
• Vehicle speed sensor
• Heated oxygen sensors
KNOCK SENSOR (2.4L only)
The knock sensor provides an input to the Power-
train Control Module (PCM) on circuit K42. Circuit
K42 connects to cavity 24 of the PCM connector.
The knock sensor is case grounded to the engine
block.
HELPFUL INFORMATION
Refer to group 14, for knock sensor operation.
AMBIENT (BATTERY) TEMPERATURE SENSOR
The ambient temperature sensor draws voltage
from the Powertrain Control Module (PCM) on circuit
K118. The sensor is a variable resistor. As tempera-
ture changes, the resistance draw in the sensor
changes causing a change in current draw. Circuit
K118 connects to cavity 52 of the PCM connector.
The PCM provides a ground for the ambient tem-
perature sensor on circuit K4. Circuit K4 connects to
cavity 43 of the PCM connector.
HELPFUL INFORMATION
Circuit K4 splices to supply ground for the signals
from the following:
• Intake air temperature sensor
• Camshaft position sensor
