Code B1516 Chevrolet Description

The Battery Current Sensor is a 3-wire hall effect current sensor. The Body Control Module (BCM) supplies 5 V and ground to the battery current sensor. The battery current sensor measures the amount of current flowing to or from the battery, and supplies a Pulse Width Modulation (PWM) signal to the BCM. The Diagnostic Trouble Code (DTC) will be set when the BCM detects a fault with the Battery Current Sensor.

  • can a battery sensor cause a battery draw and kill the battery over night?

    • Great question.

      Yes, a faulty battery current sensor can contribute to a parasitic draw, but it's not the most common cause. The battery current sensor’s main job is to monitor charging and battery load for the vehicle’s charging system and computer. If it's malfunctioning, the system may not manage power correctly — for example, it might fail to shut down modules during sleep mode, which can lead to a slow overnight drain.

      That said, most overnight battery drains are caused by:

      1. A stuck relay (like for fuel pump or HVAC).
      2. A module not going to sleep (radio, infotainment, BCM, etc.).
      3. Aftermarket accessories drawing power (alarms, remote starts, dash cams).

      To confirm, you’d want to do a parasitic draw test using a multimeter. If you suspect the sensor, try unplugging it overnight (if accessible) and see if the battery holds charge. If it does, the sensor or its related circuit may be the issue.
