P0713 Subaru Code - Transmission Fluid Temperature Sensor High Input

Quick Answer

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. Common causes include Faulty Transmission Fluid Temperature Sensor, Transmission Fluid Temperature Sensor harness is open or shorted, Transmission Fluid Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0713 Subaru Description

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases. The Transmission Control Module (TCM) monitors the ATF (Automatic Transmission Fluid) Temperature Sensor signal. The TCM sets the OBDII code when the ATF (Automatic Transmission Fluid) Temperature Sensor signal is out of factory specifications.

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.
