P0517 RAM Code - Battery Temperature Sensor Circuit High
Quick Answer
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery. Common causes include Faulty Battery Temperature Sensor, Battery Temperature Sensor harness is open or shorted, Battery Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0517 RAM Description
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. System voltage will be higher at colder temperatures and is gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As temperature increases, resistance in the sensor decreases and the detection voltage at the PCM increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection Pump (LDP) and O2 sensor heater tests). Most OBD II monitors are disabled below 20°F.
What are the Possible Causes of the DTC P0517 RAM?
- Faulty Battery Temperature Sensor
- Battery Temperature Sensor harness is open or shorted
- Battery Temperature Sensor circuit poor electrical connection
