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

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.
