Code P0AC7 2014 Chevrolet Silverado Description

Hybrid/EV Battery Temperature Sensors are used to monitor the battery temperature. The non-serviceable battery temperature sensors are located within the battery sections. Two temperature sensors are located in each battery section. The temperature sensor is a variable resistor that measures the temperature of the battery cell group. The hybrid/EV interface control module supplies 5 V to the signal circuit and is a ground for the low reference circuit. The battery temperature sensor resistance changes with battery temperature. As the temperature decreases, the sensor resistance increases. As the temperature increases, the sensor resistance decreases.
Each Hybrid/EV Battery Interface Control Module communicates the temperature sensor values to the Hybrid/EV Powertrain Control Module via serial data.
The Hybrid/EV Powertrain Control Module uses the battery temperature sensors to determine the Hybrid/EV Battery Module temperature in order to control the battery cooling system operation.
The Diagnostic Trouble Code (DTC) will be set when the hybrid battery temperature sensor is greater than 160°C (320°F).
