Code P0713 2015 GMC Sierra Description
The P0713 diagnostic trouble code (DTC) for a 2015 GMC Sierra indicates a problem with the Transmission Fluid Temperature Sensor Circuit High Voltage. This sensor is responsible for monitoring the temperature of the transmission fluid, which is crucial for ensuring optimal performance and longevity of the transmission system. When the sensor detects a high voltage signal, it suggests that the transmission fluid temperature is higher than normal, potentially indicating overheating or other issues.
Common Causes of P0713 2015 GMC Sierra
- Faulty Temperature Sensor: The most common cause of this code is a malfunctioning transmission fluid temperature sensor.
- Wiring Issues: Corrosion, damage, or poor connections in the sensor circuit wiring can lead to high voltage readings.
- Overheating: Actual overheating of the transmission fluid due to low fluid levels, a malfunctioning cooling system, or heavy towing loads can trigger this code.
- Software or Calibration Issues: Occasionally, software glitches or calibration errors in the transmission control module can cause false high voltage readings.
Symptoms of P0713 2015 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Transmission Overheating Warning: Some vehicles may display a warning message indicating transmission overheating.
- Harsh Shifting: The transmission may exhibit harsh or delayed shifting due to incorrect temperature readings.
- Reduced Fuel Efficiency: Overheating can lead to increased friction and inefficiency in the transmission, resulting in reduced fuel economy.
- Transmission Slipping: In severe cases, the transmission may slip or fail to engage properly due to overheating.
How to Fix P0713 2015 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the specific trouble code and perform a thorough inspection of the transmission fluid temperature sensor and its circuit.
- Replace the Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Check Wiring and Connections: Inspect the wiring harness and connectors for any damage, corrosion, or loose connections. Repair or replace as needed.
- Clear the Code: After completing the repair, clear the trouble code from the vehicle's computer using the scan tool.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the transmission operates normally.
Cost to Fix P0713 2015 GMC Sierra
