Code P0AC6 2016 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 difference between a single battery temperature sensor and an average of the other battery temperature sensors is greater than 25°C (45°F).

Frequently Asked Questions about P0AC6 2016 Chevrolet Silverado Code

1. What does the OBDII code P0AC6 mean on a 2016 Chevrolet Silverado?

The P0AC6 code indicates an issue with the performance of Hybrid/EV Battery Temperature Sensor 2, which monitors the temperature of the hybrid battery pack.

2. What are the common symptoms of the P0AC6 code?

Symptoms may include the hybrid system warning light illuminating, reduced fuel efficiency, limited hybrid system performance, or the vehicle entering a fail-safe mode.

3. What causes the P0AC6 code to appear?

Common causes include a faulty battery temperature sensor, wiring or connector issues in the sensor circuit, or a malfunctioning hybrid battery control module.

4. Can I drive my 2016 Chevrolet Silverado with the P0AC6 code?

Itâ€™s not recommended to drive the vehicle extensively, as the hybrid system may not function correctly, potentially leading to reduced performance or further damage.

5. How can the P0AC6 code be diagnosed?

Diagnosis involves using a scan tool to check for related codes, inspecting the wiring and connectors for damage, and testing the battery temperature sensor for proper operation.

6. How do I fix the P0AC6 code on my Silverado?

Repairs may include replacing the faulty battery temperature sensor, repairing damaged wiring or connectors, or reprogramming/updating the hybrid battery control module.

7. How much does it cost to fix the P0AC6 code?

Repair costs can vary but typically range from $150 to $500 depending on whether the issue is with the sensor, wiring, or control module.

8. Can a low hybrid battery charge trigger the P0AC6 code?

No, a low battery charge itself does not trigger this code, but temperature sensor issues could indirectly affect battery performance and charge regulation.

9. Is the P0AC6 code specific to hybrids or EVs?

Yes, the P0AC6 code is specific to hybrid and electric vehicles, as it relates to the hybrid battery temperature monitoring system.

10. Do I need to reprogram the hybrid system after fixing the P0AC6 code?

In some cases, reprogramming or resetting the hybrid battery control module may be required after repairs to clear the code and restore normal operation.
