General Description

CIRCUIT OPERATION
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 52 of the PCM connector.

The PCM provides ground for the battery temperature sensor signal (circuit G31) through circuit K4. Circuit K4 connects to cavity 43 of the PCM connector.
