- Damaged wiring or connections in the sensor circuit
- Corrosion on electrical connections
- Faulty battery
Related parts
- Battery Temperature Sensor: Batteries are temperature-sensitive and a battery's optimal operating temperature range is 40 to 70 degrees Fahrenheit. Battery temperature sensor monitors battery temperature during charging. If it senses a temperature variation, it orders the computer control system to change the charging rate. Problems make it hard to start car and may cause stalling
Possible solutions
- Replace the battery temperature sensor
- Check and repair any damaged wiring or connections
- Clean any corroded electrical connections
- Replace the battery if necessary
