OBD-II Trouble Code P0517: Battery Temperature Sensor Circuit High

diagnostic check engine light

P0517 code definition

The P0517 code is generic powertrain code related to the vehicle’s speed controls and idle control system-related problems. In this case, the engine control module (ECM) has detected a high voltage reading from the battery temperature circuit.

What the P0517 code means

A code P0517 will be stored when the ECM has been sent a high voltage reading from the battery temperature sensor; typical readings are around 5-volts). The ECM will utilize battery temperature sensor input data, as well as charging system voltage data, to determine the rate the alternator will charge the battery. It will also use battery temperature as a base for activating heated oxygen sensors as well as evaporative emissions control system components.

To read the battery temperature, a 5-volt reference signal is sent from the PCM to the battery temperature sensor, which is grounded through the sensor return circuit. When battery temperature increases, it decreases the sensor resistance the ECM will receive a voltage signal that is higher. When the battery temperature decreases, the voltage signal decreases.

Usually located beneath the battery in the battery tray, it is frequently part of the battery tray.

What causes the P0517 code?

Several problems may cause a P0517 code including:

What are the symptoms of the P0517 code?

Symptoms of a P0517 code may include:

How does a mechanic diagnose the P0517 code?

A mechanic may use several methods to diagnose a P0517 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P0517 trouble code
  • Visually inspect all wiring and related electrical connectors for signs of damage
  • Test battery to ensure it is fully charged
  • Inspect and test electrical circuits related to the battery temperature sensor for signs of damage
  • Test battery temperature sensor for a ground signal and test for a system voltage signal
  • Test resistance of battery temperature sensor

Common mistakes when diagnosing the P0517 code

A common mistake when diagnosing or repairing a P0517 code is replacing the battery itself, when the problem is typically related to the sensor in the battery tray.

How serious is the P0517 code?

Because a vehicle’s safe driving operation could be impacted due to faults that store a P0517 code, although most likely in a minor way, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.

What repairs can fix the P0517 code?

Several repairs can fix a P0517 trouble code and include:

Additional information related to a P0517 code

Because the battery temperature sensor also relates to activating the heated oxygen sensor and evaporative emissions systems, codes related to both may accompany a stored P0517 code.
