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:
- A stuck relay (like for fuel pump or HVAC).
- A module not going to sleep (radio, infotainment, BCM, etc.).
- 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.
