The OBD-II (On-Board Diagnostics) system is built into modern vehicles, responsible for detecting and reporting any problems that may arise within the engine or transmission systems. These problems are detected through the use of various sensors and computer systems, with the resulting diagnostic codes used to identify the specific issue. One such code is P0713, which relates to the Transmission Fluid Temperature Sensor A Circuit High. In this article, we will explore this code in-depth, explaining what it means, its potential causes, and how to fix the problem.
Understanding OBD-II Code P0713
When the OBD-II system in a vehicle detects an issue with the transmission fluid temperature sensor (TFT), it will generate the P0713 code. This code indicates that the TFT sensor is reporting a temperature that is higher than it should be, within the first transmission range. This means that the sensor is detecting a high voltage or resistance level, causing the ECM (Engine Control Module) to trigger the code.
Potential Causes of OBD-II Code P0713
There can be various potential causes of the P0713 code, including:
1. Malfunctioning TFT sensor – The sensor itself may be failing, detecting a higher temperature than is actually present.
2. Wiring issues – There may be an issue with the wiring connecting the sensor to the ECM, which can result in a high voltage or resistance level.
3. Faulty ECM – The ECM may be damaged, causing it to receive incorrect information from the TFT sensor and triggering the code.
4. Transmission fluid issues – The transmission fluid may be overheating due to a low fluid level, a lack of proper maintenance, or a faulty transmission cooler.
Fixing OBD-II Code P0713
Thankfully, there are ways to fix the P0713 code once it has been identified. Here are some of the most common solutions:
1. Replacing the TFT sensor – If the sensor itself is the issue, it will need to be replaced. This is a relatively easy and inexpensive fix.
2. Checking the wiring – If the wiring is damaged or otherwise not functioning correctly, it can be repaired or replaced.
3. Repairing or replacing the ECM – If the ECM is the issue, it may need to be repaired or replaced. This can be more costly and time-consuming than other solutions.
4. Checking the transmission fluid – If the transmission fluid is overheating, it may simply need to be topped off or replaced. It’s important to ensure that the transmission fluid is at the correct level and that it is being maintained correctly.
Frequently Asked Questions:
1. What is a Transmission Fluid Temperature Sensor (TFT)?
The Transmission Fluid Temperature Sensor (TFT) is a sensor that sends information to the engine control module about the temperature of the transmission fluid. This information can be used to adjust the transmission’s performance and ensure optimal driving conditions.
2. Can I ignore the P0713 code?
While it may be tempting to ignore the P0713 code, it’s essential to address the issue as soon as possible. Ignoring the code can lead to further damages to the transmission system, resulting in more costly repairs in the long run.
3. How much will it cost to fix the P0713 code?
The cost of fixing the P0713 code will depend on the exact issue causing the problem. Simple fixes such as replacing the TFT sensor or repairing wiring may be relatively inexpensive, while more complex solutions like replacing the ECM can be more costly.
4. Can I fix the P0713 code on my own?
While it is possible for advanced DIY mechanics to fix the P0713 code, we recommend taking your vehicle to a professional mechanic. A trained mechanic will have the expertise and tools needed to diagnose and fix the issue correctly.
5. Can I prevent the P0713 code from appearing?
Proper transmission maintenance can help prevent the P0713 code from appearing. Regularly replacing transmission fluid, checking fluid levels, and addressing any transmission issues as soon as they arise can help prevent the code from triggering.
In conclusion, the OBD-II Code P0713 – Transmission Fluid Temperature Sensor A Circuit High is one that should not be ignored. Still, with proper diagnosis and repair, it can be fixed relatively easily. By understanding the potential causes of the issue and taking prompt action, vehicle owners can keep their cars running smoothly and prevent further damage to the transmission system.
