Code P0713 2014 GMC Sierra Description
The P0713 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a problem with the transmission fluid temperature sensor circuit registering high voltage. The transmission fluid temperature sensor is a crucial component that monitors the temperature of the transmission fluid. This information is essential for the vehicle's computer system to adjust various parameters, such as shift points, torque converter lockup, and overall transmission performance.
Common Causes of P0713 2014 GMC Sierra
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be malfunctioning, causing it to send incorrect voltage readings to the vehicle's computer.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the vehicle's computer can lead to high voltage readings.
- Transmission Fluid Issues: Low or contaminated transmission fluid can cause the transmission to overheat, triggering the high voltage reading.
- Engine Overheating: If the engine is overheating, it can transfer excess heat to the transmission, leading to high fluid temperatures.
- Faulty Vehicle Computer: In rare cases, a malfunction in the vehicle's computer system can cause erroneous readings from the transmission fluid temperature sensor.
Symptoms of P0713 2014 GMC Sierra
- Illuminated Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Transmission Overheating Warning: Some vehicles may display a warning message indicating that the transmission is overheating.
- Harsh Shifting: High transmission fluid temperatures can cause the transmission to shift harshly or inconsistently.
- Transmission Slipping: The transmission may slip or struggle to engage properly due to the high fluid temperature.
- Decreased Fuel Efficiency: A malfunctioning transmission fluid temperature sensor can lead to decreased fuel efficiency as the transmission may not operate optimally.
How to Fix P0713 2014 GMC Sierra
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the specific trouble code and confirm the issue with the transmission fluid temperature sensor.
- Sensor Replacement: Replace the faulty transmission fluid temperature sensor with a new, OEM-quality sensor.
- Check Wiring: Inspect the wiring harness connecting the sensor to the vehicle's computer for any damage or corrosion. Repair or replace as necessary.
- Transmission Fluid Service: Perform a transmission fluid flush and fill with the manufacturer's recommended fluid to ensure proper transmission operation.
- Clear Codes: After completing the repairs, clear the trouble codes from the vehicle's computer system and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0713 2014 GMC Sierra
The cost of repairing a P0713 code on a 2014 GMC Sierra can vary depending on the specific cause of the issue. On average, the cost of replacing a transmission fluid temperature sensor ranges from $100 to $200, including parts and labor. If additional repairs or diagnostics are needed, the total cost could increase. It's important to note that labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. Factors such as location, vehicle make and model, and engine type can also impact repair costs. For a more accurate estimate, it's recommended to consult with a local auto repair shop.

Frequently Asked Questions about P0713 2014 GMC Sierra Code
What does the OBDII code P0713 mean on a 2014 GMC Sierra?
The P0713 code indicates that the Transmission Fluid Temperature (TFT) sensor is reporting a high voltage signal, which typically means it is detecting an unusually low temperature.
What are the common symptoms of the P0713 code?
Symptoms may include harsh or erratic shifting, the transmission staying in one gear, poor fuel economy, or the check engine light illuminating.
What causes the P0713 code to appear on a 2014 GMC Sierra?
Common causes include a faulty transmission fluid temperature sensor, damaged wiring or connectors, a poor electrical connection, or a malfunctioning powertrain control module (PCM).
Can a low transmission fluid level trigger the P0713 code?
Not directly, but low fluid levels can cause overheating or incorrect sensor readings, which may contribute to transmission issues.
How do you diagnose the P0713 code?
Diagnosis involves checking the TFT sensor, inspecting the wiring and connectors for damage or corrosion, and using a scan tool to monitor sensor voltage and temperature readings.
Can I drive my 2014 GMC Sierra with the P0713 code active?
It is not recommended to drive for extended periods with this code active, as it may lead to improper transmission operation and further damage.
How is the P0713 code fixed?
Repairs may include replacing the transmission fluid temperature sensor, repairing or replacing damaged wiring, or cleaning corroded connectors.
Does the P0713 code mean the transmission is failing?
Not necessarily; the code typically points to an issue with the sensor or its circuit rather than the transmission itself.
What tools do I need to fix the P0713 code?
You may need a multimeter to test the sensor and wiring, a scan tool to read and clear codes, and basic hand tools for sensor replacement or wiring repairs.
How much does it cost to fix the P0713 code on a 2014 GMC Sierra?
Repair costs vary but typically range from $150 to $400, depending on whether the issue is with the sensor, wiring, or connectors.
