There are some precautions when replacing the battery if a vehicle has the battery current sensor. Replacing/charging the battery in the vehicle with a battery sensor If there are any added electrical accessories that are connected directly to the negative terminal bypassing the battery sensor, this may also cause problems. If there is a fault related to the battery sensor, the first step is to check it visually for corrosion, cracks, physical damage, loose battery terminals or battery cable connections, corroded pins at the connector or broken wires.

You can find the proper diagnostic procedure in the service manual for your vehicle. In some cars, using a scan tool, a mechanic can check the state of charge (SOC), the state of health and other parameters of the battery. Some require measuring the resistance between the sensor pins, others advise using a scan tool to test the sensor. We looked at diagnostic procedures from several car makers, and they are all different. The most difficult part is to diagnose the problem correctly, and it's not always easy. In some cars, a battery sensor comes together with the battery cable.

An auto repair shop may charge you $50-$210 for the part plus $35-$110 labor. Replacing the battery sensor is not very expensive. In many vehicles, a bad battery sensor can cause the Stop/Start system not to work. For example, the owner's manual for the 2019 Ford Explorer advises not to connect any electrical device ground connection directly to the low voltage battery negative post to ensure proper operation of the battery management system (BMS). If a car has a battery current sensor and additional electrical accessories are connected directly to the battery negative terminal, it may cause problems, because the electric current will bypass the battery current sensor and its readings won't be accurate. According to the bulletin 17-069, the moisture and road salt getting into the sensor "could result in an electrical short and, subsequently, a fire." Honda issued the recall (service bulletins 17-057 and 17-069) to check and, if needed, replace the battery management sensor in the 2013-2016 Honda Accord (except Hybrid).

A faulty battery sensor can also cause the code P154A in some Acura vehicles. The bulletin advises changing the battery sensor. The Honda bulletin 16-026 for various Accord, Fit and HR-V models describes a problem where a faulty battery sensor can cause Charging System Indicator to come on with the trouble code (DTC) P154A. A battery sensor is a fragile device and can also be damaged when servicing or removing the battery. A failed IBS is known to cause a variety of electrical problems, including a no-start. BMW calls it the Intelligent Battery Sensor, or IBS. For example, in some BMW vehicles, the battery is located in the side compartment in the trunk and water leaking onto the battery can damage the sensor. The most common problem is when the dirt, moisture or battery acid get into the sensor and damage or short it. To function properly, the battery sensor must be clean and dry, and the pole terminal must be tight. Many electrical problems, including issues with the battery current sensor can be caused by loose or corroded battery terminals or moisture/corrosion around the battery sensor. For this reason, in some vehicles, if the sensor has been disconnected or the battery has been replaced, the Stop-Start feature might not work for some time, until the computer (BCM or PCM) re-learns the parameters of the battery. The charging system current is also often higher in vehicles with Stop-Start feature. If the battery is low on charge, the Stop-Start feature is disabled. Verify that the battery has enough charge to re-start the vehicle. The function of the battery sensor is particularly important in vehicles with Stop-Start feature, as the battery management system must
