Common questions

Where is the temperature sensor on a battery?

Where is the temperature sensor on a battery?

The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery. The BTS is used to determine the battery temperature and control battery charging rate. This temperature data, along with data from monitored line voltage, is used by the PCM to vary the battery charging rate.

Where is the battery temp sensor on a Cummins diesel?

Battery temperature sensor is snapped into battery tray below driver’s side battery. 1.Battery temperature sensor is snapped into battery tray, below driver’s side battery. Disconnect wiring harness at battery temperature sensor. 2.Using ohmmeter, check resistance between electrical terminals on battery temperature sensor.

What are the symptoms of a bad temperature sensor?

Another symptom of a bad or failing temperature sensor is 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.

What does a temperature sensor on a car do?

As its name suggests, battery temperature sensors detect the temperature of the battery so that the charging system voltage can be increased or decreased according to the vehicle’s needs.

What to do if battery temp sensor is not working?

Disconnect wiring harness at battery temperature sensor. 2.Using ohmmeter, check resistance between electrical terminals on battery temperature sensor. Resistance should be 9000-11,000 ohms at 75-80°F (25-27°C). Replace battery temperature sensor if resistance is not within specification.

Battery temperature sensor is snapped into battery tray below driver’s side battery. 1.Battery temperature sensor is snapped into battery tray, below driver’s side battery. Disconnect wiring harness at battery temperature sensor. 2.Using ohmmeter, check resistance between electrical terminals on battery temperature sensor.

How does a battery temperature sensor work on a car?

As its name suggests, battery temperature sensors detect the temperature of the battery so that the charging system voltage can be increased or decreased according to the vehicle’s needs. When the battery temperature is low, the system voltage is set high and will automatically decrease as the temperature increases.

Another symptom of a bad or failing temperature sensor is 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.
