A P0713 trouble code is related to a vehicle’s automatic transmission temperature sensor and the automatic transmission fluid itself. The code is triggered when the transmission control module (TCM) reads voltage that is too high for the manufacturer’s parameters, indicating that the automatic transmission fluid is too hot. Common causes for the P0713 code include low automatic transmission fluid, dirty automatic transmission fluid, faulty temperature sensor, slipping or damaged transmission, damaged sensor wiring, and a faulty TCM or engine control module.
Key Takeaways:
- The P0713 code is related to a malfunction in the transmission control system.
- It is triggered when the transmission control module detects high voltage, indicating an overheating automatic transmission fluid.
- Possible causes include low fluid levels, dirty fluid, faulty temperature sensor, transmission damage, and faulty control modules.
- Symptoms of the P0713 code may include poor shifting, “limp mode,” illuminated A/T Oil Temp light, and visible smoke.
- Diagnosis involves inspecting for leaks, testing the temperature sensor, and a thorough test drive to bring fluid to operating temperature.
Symptoms of the P0713 Code
When the P0713 code manifests in a vehicle’s transmission control system, there are several telltale signs that can help identify the issue. Recognizing these symptoms is crucial, as ignoring the problem could lead to severe transmission damage and expensive repairs.
Here are the common symptoms associated with the P0713 code:
- Poor Shifting: One of the primary indicators of a P0713 code is a noticeable change in shifting performance. The transmission may experience delays, hesitate when changing gears, or shift erratically.
- “Limp Mode”: The vehicle may enter a mode commonly referred to as “limp mode” or “limp-home mode.” This mode imposes specific driving parameters aimed at allowing the vehicle to reach a repair facility safely. In this mode, the vehicle’s performance is significantly reduced, and the engine may not rev beyond a certain limit.
- Illuminated A/T Oil Temp Light: If the vehicle is equipped with an A/T Oil Temp light, it may illuminate when the P0713 code is present. This serves as a warning that the transmission is experiencing issues related to its temperature.
- Visible Smoke: In cases where the P0713 code is triggered by low fluid levels resulting from a leak, visible smoke may emit from the vehicle. This smoke is a sign that the transmission fluid is leaking and coming into contact with hot components.

As soon as any of these symptoms are noticed, it is important to address the P0713 code promptly. Ignoring the issue may lead to more extensive transmission damage and result in costly repairs. Next, we will discuss the diagnosis and repair process for the P0713 code.
Diagnosing and Repairing the P0713 Code
Diagnosing the P0713 code requires a systematic approach to identify the underlying issue with the transmission control system. There are two paths to consider when troubleshooting this code.
If the transmission is shifting poorly and the A/T Oil Temp light is illuminated, it indicates a mechanical problem. In this case, the next step is to visually inspect the transmission for any leaks. Leaks are a common cause of the P0713 code and can originate from the front seal, oil pan, or rear output shaft. It’s vital to repair any leaks and refill the transmission fluid with the manufacturer’s recommended variety.
If the transmission seems to be in fine working order, the temperature sensor may be faulty. Testing the temperature sensor using a professional multi-meter can help determine its functionality. If the sensor is found to be faulty, it should be replaced with a high-quality part to ensure accurate temperature readings.
Once the repairs or replacement are completed, it’s essential to perform a thorough test drive to bring the transmission fluid up to operating temperature. This step will validate the effectiveness of the repairs and ensure that the transmission control system is functioning as intended.
Diagnostic Steps:
- Inspect the transmission for any leaks
- Repair any leaks found and refill the transmission fluid
- Test the temperature sensor using a professional multi-meter
- If faulty, replace the temperature sensor with a high-quality part
- Perform a test drive to bring the transmission fluid to operating temperature
By following these diagnostic steps, the underlying cause of the P0713 code can be identified and addressed effectively, ensuring the proper functioning of the transmission control system.
| Error Code | Potential Causes | Steps to Fix |
|---|---|---|
| P0713 | Low automatic transmission fluid Dirty automatic transmission fluid Faulty temperature sensor Slipping or damaged transmission Wiring issues with the sensor Faulty transmission control module or engine control module |
Inspect for leaks and repair them Refill transmission fluid with recommended variety Test and replace faulty temperature sensor Repair or replace transmission if necessary Repair or replace sensor wiring Replace faulty transmission control module or engine control module |
Severity and Repairs for the P0713 Code
The severity of the P0713 code can vary depending on the true cause. If the temperature sensor is working correctly, it indicates an overheating transmission that needs immediate attention. On the other hand, if the sensor is faulty, the transmission is likely fine and won’t require extensive repairs.
To resolve the P0713 code, there are several common repairs that can be undertaken. First, conducting a visual inspection of the transmission for leaks and checking the fluid levels is crucial. If any leaks are detected, they should be promptly repaired to prevent further damage. Additionally, it is recommended to change the transmission fluid, ensuring it aligns with the manufacturer’s specifications.
If the issue persists, repairing or replacing the temperature sensor and related wiring might be necessary. This can help restore the proper functioning of the transmission control system. However, if the code continues to persist and the transmission still performs poorly, considering a rebuild or replacement may be required.
| Repairs for P0713 Code | Severity Level |
|---|---|
| Visual inspection for leaks and repair | Medium |
| Changing the transmission fluid | Low |
| Repair or replacement of temperature sensor and related wiring | High |
| Consideration of rebuild or replacement | High |
P0713 Code Repairs Breakdown
- Visual inspection for leaks and repair: This repair involves thoroughly examining the transmission for any signs of leaks, such as fluid pooling or seepage. Once identified, the leaks should be repaired promptly to prevent further damage to the system.
