Battery Temperature Sensor Operation

BATTERY TEMPERATURE SENSOR
From circuit G31, the battery temperature sensor draws voltage from the Powertrain Control Module (PCM). The sensor is a variable resistor. As battery temperature changes, the resistance in the sensor changes causing a change in current draw. Circuit G31 connects to cavity 49 of the PCM connector, and cavity B of the sensor connector.

The PCM provides a ground for the battery temperature sensor signal (circuit G31) through circuit K4. Circuit K4 connects to cavity 51 of the PCM connector and cavity A of the sensor connector.
