What happens if the battery temperature sensor is low?
Low battery voltage. If the battery temperature sensor has any issue that causes it to send an incorrect signal to the computer, it can interfere with proper charging and cause low voltage. A battery with low voltage may not be able to properly start a vehicle, and may also cause other problems for the vehicle’s electrical system.
