Code P0713 Subaru Description
The P0713 diagnostic trouble code for Subaru vehicles indicates a high input signal from the transmission fluid temperature sensor. 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 higher than normal temperature, it triggers the P0713 code, indicating a potential issue that needs to be addressed.
Common Causes of P0713 Subaru
- Faulty transmission fluid temperature sensor
- Wiring issues in the sensor circuit
- Transmission control module malfunction
- Low transmission fluid level
- Overheating of the transmission system
Symptoms of P0713 Subaru
- Erratic shifting behavior
- Delayed or harsh shifting
- Transmission slipping
- Overheating warning light on the dashboard
- Transmission not engaging properly
How to Fix P0713 Subaru
- Begin by diagnosing the cause of the high input signal from the transmission fluid temperature sensor using a diagnostic scanner to retrieve the trouble codes.
- Inspect the sensor and its wiring harness for any signs of damage, corrosion, or loose connections. Replace or repair any faulty components as needed.
- Check the transmission fluid level and quality to ensure it is at the correct level and not contaminated. Perform a transmission fluid flush and refill if necessary.
- Test the transmission system to verify that the issue has been resolved and the sensor is now providing accurate temperature readings.
- Clear the trouble codes from the vehicle's computer system and test drive the vehicle to ensure that the transmission is functioning correctly.
Cost to Fix P0713 Subaru

Frequently Asked Questions about P0713 Subaru Code
1. What does the OBDII code P0713 mean on a Subaru?
P0713 indicates the Transmission Fluid Temperature (TFT) sensor is reporting a higher-than-expected voltage, suggesting the sensor may be faulty or the transmission fluid temperature is abnormally high.
2. What are common symptoms of P0713 on a Subaru?
Symptoms may include erratic shifting, the transmission going into limp mode, poor fuel economy, and the check engine light being illuminated.
3. What causes the P0713 code to appear on a Subaru?
Common causes include a faulty TFT sensor, damaged or corroded wiring, loose connections, a malfunctioning transmission control module (TCM), or extremely high transmission fluid temperatures.
4. Can I drive my Subaru with the P0713 code?
While the vehicle may still be drivable, prolonged driving with this issue could lead to transmission damage if the fluid temperature is genuinely too high. It's best to diagnose and address the issue promptly.
5. How is the P0713 code diagnosed in a Subaru?
A mechanic will typically use a scan tool to monitor live data from the TFT sensor, inspect wiring and connectors for damage, and check the actual temperature of the transmission fluid.
6. How do you fix the P0713 code on a Subaru?
Repairs might include replacing the TFT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or addressing overheating issues by changing the transmission fluid or inspecting the cooling system.
7. How much does it cost to fix a P0713 code on a Subaru?
Repair costs can vary, but replacing the TFT sensor typically ranges from $100 to $300, while wiring repairs may cost less depending on the extent of the damage.
8. Can low or dirty transmission fluid cause the P0713 code?
Yes, low or dirty transmission fluid can lead to overheating, which may trigger the P0713 code. Ensure the fluid is at the correct level and in good condition.
9. Where is the Transmission Fluid Temperature sensor located in a Subaru?
The TFT sensor is usually located inside the transmission pan or integrated into the valve body, depending on the specific Subaru model.
10. Will clearing the P0713 code fix the issue permanently?
Clearing the code without addressing the root cause will not fix the problem, and the code will likely return. Proper diagnosis and repair are essential.
