P0516 RAM Code - Battery Temperature Sensor Circuit Low
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 P0516 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 P0516 RAM?
- Faulty Battery Temperature Sensor
- Battery Temperature Sensor harness is open or shorted
- Battery Temperature Sensor circuit poor electrical connection
How to Fix the DTC P0516 RAM?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0516 RAM code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0516 RAM Code
1. What does OBDII code P0516 mean on a RAM vehicle?
Code P0516 indicates a low voltage issue in the battery temperature sensor circuit, which monitors the battery temperature to optimize charging performance.
2. What are common symptoms of code P0516 in a RAM?
Symptoms may include difficulty starting the vehicle, erratic charging behavior, a check engine light, or reduced battery performance.
3. What causes the P0516 code to appear?
Common causes include a faulty battery temperature sensor, damaged wiring or connectors, corrosion in the sensor circuit, or issues with the PCM (Powertrain Control Module).
4. Can I drive my RAM with code P0516?
While the vehicle may still operate, driving with this code can lead to charging system problems or battery damage over time. It’s best to address it promptly.
5. How do you diagnose a P0516 code on a RAM?
Diagnosis involves inspecting the battery temperature sensor, wiring, and connectors for damage or corrosion, and testing the sensor with a multimeter to verify its functionality.
6. How do you fix code P0516 on a RAM?
Repairs may include replacing the battery temperature sensor, repairing damaged wiring or connectors, cleaning corrosion, or updating/replacing the PCM if necessary.
7. What tools are needed to fix P0516 on a RAM?
Tools may include a multimeter, OBDII scanner, wire repair kit, and basic hand tools for removing and installing components.
8. How much does it cost to repair code P0516 on a RAM?
Costs vary depending on the issue but typically range from $50 to $300 for parts and labor, depending on whether the sensor or wiring needs replacement.
9. Can a low battery cause code P0516 to trigger?
Yes, a weak or failing battery can affect the sensor readings and potentially trigger this code.
10. Does the P0516 code require PCM reprogramming?
PCM reprogramming is rarely required for this code but may be necessary if the PCM itself is faulty or has incorrect calibration settings.
