Give your vehicle's charging system accurate information about the battery with the Standard Ignition Battery Current Sensor BSC3, an Intelligent Battery Sensor (IBS) that measures the battery's charge and discharge. It fits many vehicles, among them the 2013-2019 Ford Escape 1.5L / 1.6L / 2.0L / 2.5L, 2012-2018 Ford Focus and 2013-2016 Ford C-MAX 2.0L. See the Buyer's Guide tab for the full list.
This battery current and volt sensor works with the vehicle's intelligent Battery Management System (BMS) to detect low or insufficient electrical voltage. The vehicle computer uses its input to fine-tune charging voltage, idle speed and other parameters, which is designed to support fuel efficiency and battery life. Sensors like this one are common on newer vehicles with Start/Stop technology.
Connector and specs: female plug-in connector with a round, oval shape and two male blade terminals. The package contains one sensor, and the listed applications use one sensor. Country of origin: United States.
Signs this part may need replacing include a battery warning light, a Start/Stop system that no longer operates, or charging problems. These symptoms can have other causes, so diagnose the charging system before replacing the sensor.

This part cross-references / interchanges with the following part numbers:
What does a battery current sensor do?
It measures the battery's charge and discharge and reports low or insufficient voltage to the Battery Management System, which uses that input to adjust charging voltage, idle speed and other parameters.
Is this an O2 sensor for the 2013-2019 Ford Escape 1.5L / 1.6L / 2.0L / 2.5L?
No. The BSC3 is a battery current/volt sensor, not an oxygen sensor. It is listed as a direct-fit replacement for that Escape; check the Buyer's Guide tab for your exact vehicle.
Which other vehicles does this battery sensor fit?
Among others, the 2012-2018 Ford Focus and the 2013-2016 Ford C-MAX 2.0L. See the Buyer's Guide tab for the full list of applications.
What are the connector specs, and what is in the box?
The package contains one sensor. It has a female plug-in connector with a round, oval shape and two male blade terminals, and the listed applications use one sensor.
What are signs a battery sensor may need replacing?
A battery warning light, a Start/Stop system that stops working, or charging problems may indicate a faulty sensor. These have other causes too, so diagnose the charging system first.
