Code P0ACB 2016 GMC Sierra Description
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).
What are the Possible Causes of the DTC P0ACB 2016 GMC Sierra?
- Faulty Hybrid/EV Battery Assembly
- Hybrid/EV Battery Assembly harness is open or shorted
- Hybrid/EV Battery Assembly circuit poor electrical connection
- Faulty Hybrid/EV Battery Interface Control Module

Frequently Asked Questions about P0ACB 2016 GMC Sierra Code
1. What does the OBDII code P0ACB mean on a 2016 GMC Sierra?
P0ACB indicates an issue with the performance of Hybrid/EV Battery Temperature Sensor 3, which monitors the temperature of the hybrid battery to ensure safe operation.
2. What are the symptoms of code P0ACB in a 2016 GMC Sierra?
Common symptoms include the check engine light illuminating, reduced fuel efficiency, limited hybrid system performance, or potential overheating of the hybrid battery.
3. What causes the P0ACB code to appear?
The code can be triggered by a faulty battery temperature sensor, damaged wiring or connectors, a malfunction in the hybrid battery control module, or excessive heat in the battery pack.
4. Can I drive my 2016 GMC Sierra with the P0ACB code active?
While the vehicle may remain drivable, it is not recommended as the hybrid system may not function properly, potentially leading to battery damage or reduced performance.
5. How do I diagnose the P0ACB code on my GMC Sierra?
Diagnosis involves scanning for codes with an OBDII scanner, inspecting the wiring and connectors for damage, and testing the battery temperature sensor for proper operation.
6. How do I fix the P0ACB code on a 2016 GMC Sierra?
Repairs may include replacing the faulty temperature sensor, fixing damaged wiring or connectors, updating the hybrid control module software, or replacing the hybrid battery pack if necessary.
7. What is Hybrid/EV Battery Temperature Sensor 3?
It is a sensor that monitors the temperature of a specific section of the hybrid battery pack to ensure it operates within safe temperature ranges.
8. How much does it cost to repair the P0ACB code on a GMC Sierra?
Repair costs can vary, ranging from $100 to $300 for sensor replacement, but may be higher if additional components like wiring or the battery pack need repair.
9. Can a dead 12V battery trigger the P0ACB code?
While unlikely, a weak or failing 12V battery can sometimes cause hybrid system errors, so it’s worth testing during diagnostics.
10. Will clearing the P0ACB code fix the problem?
Clearing the code without addressing the underlying issue will only temporarily remove the warning, and the code is likely to return. Proper diagnostics and repairs are necessary.
