DESCRIPTION AND OPERATION (Continued)
B29 of the PCM. Circuit K6 from cavity B31 of the
PCM supplies 5 volts to the sensor. The PCM pro-
vides ground for the govenor pressure sensor on cir-
cuit K4. Circuit K4 connects to cavity A4 of the PCM.
The governor pressure sensor is part of the trans-
mission solenoid assembly.
TRANSMISSION TEMPERATURE SENSOR
The transmission temperature sensor is located in
the transmission solenoid assembly. The Powertrain
Control Module (PCM) supplies 5 volts to the sensor
on circuit K6. Circuit T54 from the sensor connects to
cavity B1 of the PCM and provides the transmission
temperature input. The PCM provides ground for the
sensor on cavity K4.
If transmission temperature exceeds a calibrated
temperature, the PCM sends a signal to the Vehicle
Information Center (VIC) over the CCD bus. In
response, the VIC displays a message to the driver.
HELPFUL INFORMATION
Circuit K6 also supplies 5 volts to the vehicle speed
sensor.
