P0517 is a diagnostic trouble code (DTC) for "Battery Temperature Sensor Circuit High". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
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.
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.
Several problems may cause a P0517 code including:
Symptoms of a P0517 code may include:
A mechanic may use several methods to diagnose a P0517 trouble code, including:
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.
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.
Several repairs can fix a P0517 trouble code and include:
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.
