Code P06B1 2015 GMC Sierra Description

The P06B1 diagnostic trouble code (DTC) for the 2015 GMC Sierra indicates that there is a low voltage condition in the sensor supply voltage circuit. This code is typically associated with the vehicle's engine control module (ECM) detecting a voltage that is below the specified range for the sensor supply voltage circuit. The sensor supply voltage circuit is responsible for providing power to various sensors in the vehicle, allowing them to function properly and provide accurate data to the ECM for optimal engine performance.
