P0517 — Battery Temperature Sensor Signal Above Maximum Signal Operating Range during Self Test

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0517

P0517 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0517 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0517 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0517 fault code is set when the Engine Control Module (ECM) detects that the signal from the battery temperature sensor is above the maximum operating range during a self-test procedure. This sensor measures the temperature of the vehicle's battery, which is crucial for optimal battery management, including charging and preventing damage due to extreme temperatures. A signal that is too high could indicate a sensor malfunction or an actual condition where the battery temperature is excessively high. This condition can be caused by a faulty sensor, problems with the wiring or connectors, o...
