The automobile fault code p0517 can be caused by a faulty battery temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit.

  • The fault code p0517 can be caused by the following: a faulty Battery Temperature Sensor (Built into the Generator control ECU assembly), an open or shorted Battery Temperature Sensor harness, or a poor electrical connection in the Battery Temperature Sensor circuit.

To fix the automobile fault code p0517, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0517, first, check the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix typically takes around 1.0 hour to complete.

The factors influencing the diagnosis and fixing cost of the automobile fault code p0517 are the estimated repair time of 1.0 hour and the average hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P0517 fault code refers to a problem with the battery temperature sensor circuit in the vehicle. This sensor is located within the generator control ECU assembly and is responsible for detecting the temperature of the battery. It contains a thermistor that changes its resistance based on the battery temperature.

When the resistance of the thermistor is abnormally high for 0.5 seconds or more with the ignition switch ON, the generator control ECU assembly will reduce the charging current to protect the battery.

This abnormality triggers the P0517 fault code, indicating a high battery temperature sensor circuit.

What are the possible causes of fault code p0517 in an automobile?

If you’re experiencing an engine light on or a service engine soon warning light, along with engine overheating, the fault code P0517 could be the culprit. This code is often caused by a faulty battery temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes mentioned above for a comprehensive solution.
