Symptoms of a Bad or Failing Battery Temperature Sensor
A battery temperature sensor is also called the electronic battery sensor (EBS) or intelligent battery sensor (IBS) in some vehicles. This sensor is typically a thermistor by nature, meaning that it measures resistance in a circuit based on the ambient temperature. EBS usually consists of two wires located on the negative battery terminal.
