P06B1 2016 GMC Sierra Code - Sensor Supply Voltage Circuit Low Voltage
Quick Answer
The generator control module, also called the starter/generator control module is comprised of the following three control modules: the hybrid/EV powertrain control module 1, the 14 V power module, and the drive motor control module. Common causes include Faulty Starter/Generator Control Module, Starter/Generator Control Module harness is open or shorted, Starter/Generator Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P06B1 2016 GMC Sierra Description
The drive motor control module uses an internal 15 V reference power supply in order to operate the drive motor sensors and processor. This fault is handled inside the generator control module and no external circuits are involved.
The Diagnostic Trouble Code (DTC) will be set when the reference voltage is less than 8.8 V for 1 second.
What are the Possible Causes of the DTC P06B1 2016 GMC Sierra?
- Faulty Starter/Generator Control Module
- Starter/Generator Control Module harness is open or shorted
- Starter/Generator Control Module circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P06B1 2016 GMC Sierra Code
What does the OBDII code P06B1 mean for a 2016 GMC Sierra?
The P06B1 code indicates a "Sensor Supply Voltage Circuit Low Voltage," meaning the voltage supplied to one or more sensors is below the expected range.
What are the common symptoms of the P06B1 code in a 2016 GMC Sierra?
Symptoms may include a check engine light, poor engine performance, decreased fuel efficiency, and potential issues with starting or stalling.
What causes the P06B1 code to appear in a 2016 GMC Sierra?
Common causes include a faulty powertrain control module (PCM), damaged wiring or connectors in the sensor supply circuit, or a failing sensor drawing excessive current.
Can a bad PCM cause the P06B1 code in a 2016 GMC Sierra?
Yes, a malfunctioning PCM can cause the P06B1 code if it fails to regulate or supply the correct voltage to the sensors.
How do I diagnose the P06B1 code on my 2016 GMC Sierra?
Diagnosis involves using a multimeter to check sensor supply voltage, inspecting wiring and connectors for damage, and testing the PCM for functionality.
Can I drive my 2016 GMC Sierra with a P06B1 code?
Driving with a P06B1 code is not recommended, as it can lead to further engine performance issues or damage if the problem persists.
How do I fix the P06B1 code on a 2016 GMC Sierra?
Repairs may involve replacing damaged wiring, connectors, or sensors, or reprogramming or replacing the PCM if it’s faulty.
Is the P06B1 code specific to certain sensors in the 2016 GMC Sierra?
The P06B1 code generally relates to the voltage supplied to multiple sensors, so the affected sensor(s) must be identified during diagnosis.
Does clearing the P06B1 code solve the issue on a 2016 GMC Sierra?
Clearing the code will turn off the check engine light temporarily, but the underlying issue must be fixed to prevent the code from returning.
What tools are needed to troubleshoot the P06B1 code in a 2016 GMC Sierra?
You’ll need an OBDII scanner, a multimeter, and possibly a wiring diagram for the sensor circuits to perform a thorough diagnosis.
