Imagine this: You’re driving your Ford down the highway, feeling the wind in your hair, when suddenly the engine starts to sputter and the check engine light flashes on your dashboard. You pull over, check under the hood, but everything seems fine. Then, you plug in your OBD2 scanner, and there it is – a dreaded P0713 code. What does it mean, and what can you do about it?
Understanding Ford OBD Code P0713
The P0713 OBD code stands for “Transmission Fluid Temperature Sensor/Switch ‘A’ Circuit Malfunction.” This code indicates a problem with the transmission fluid temperature sensor, also known as the transmission temperature sensor (TTS). This sensor plays a crucial role in regulating the transmission fluid temperature, which is essential for smooth gear shifting and optimal performance.
The Importance of the Transmission Fluid Temperature Sensor
Think of the transmission fluid temperature sensor as a thermometer for your transmission. It monitors the temperature of the transmission fluid, and relays that information to the transmission control module (TCM). The TCM then uses this information to adjust the transmission’s operation, ensuring that the fluid stays within a safe temperature range.
P0713 Code Explained: What Does It Mean?
A P0713 code means that the TCM has detected a malfunction in the circuit that connects the transmission fluid temperature sensor to the TCM. This could be caused by a variety of factors, such as:
- A faulty transmission fluid temperature sensor: The sensor itself may be damaged or worn out.
- A broken wire or connection: A wire leading to or from the sensor may be broken, corroded, or loose.
- A faulty TCM: In rare cases, the TCM itself may be faulty and causing the error.
Troubleshooting the P0713 Code: Finding the Cause
“How do I troubleshoot this code, and what tools do I need?”
Diagnosing the issue involves a series of steps to pinpoint the exact cause of the malfunction. Here’s a comprehensive guide:
1. Inspect the Transmission Fluid Temperature Sensor
“I want to inspect the sensor myself, but I’m not sure where it is. How do I find it?”
First, consult your Ford’s service manual or search for a diagram of your transmission’s components online. The transmission fluid temperature sensor is typically located on the side of the transmission housing, near the transmission fluid pan.
“Can you show me how to locate it?”

“Once I find it, what do I look for?”
Visually inspect the sensor for any signs of damage, corrosion, or loose connections. A damaged sensor might be cracked or have a broken wire.
2. Check the Wiring and Connections
“What do I do next if the sensor looks fine?”
After inspecting the sensor, trace the wiring harness that leads from the sensor to the TCM. Look for any signs of damage, corrosion, or loose connections. If the wires are damaged, you’ll need to replace them.
3. Test the Transmission Fluid Temperature Sensor (with a multimeter)
“My sensor looks fine, and the wires are okay. Is there anything else I can check?”
Using a multimeter, test the sensor to verify its resistance value. Consult your Ford’s service manual for the specific resistance values expected for your model. A sensor that is outside the expected range is likely faulty.
4. Inspect the TCM
“What if the sensor, wires, and connections all look good?”
If you’ve checked the sensor, wiring, and connections, and everything looks good, you may have a problem with the TCM. However, TCM issues are relatively uncommon.
How to Fix the P0713 Code
“What do I need to do to fix the issue?”
After identifying the problem, you can start making repairs. Here are the possible solutions:
- Replace the transmission fluid temperature sensor: If the sensor is faulty, it will need to be replaced. This is usually a straightforward repair that involves disconnecting the sensor and installing a new one.
- Repair or replace the wiring: If the wires are damaged, they need to be repaired or replaced. This may involve splicing in new sections of wire or replacing the entire wiring harness.
- Repair or replace the TCM: In rare cases, the TCM may need to be repaired or replaced. This is a more complex procedure that should be performed by a qualified mechanic.
“I don’t feel comfortable doing this myself. Who can I trust to help?”
If you’re not comfortable doing the repairs yourself, it’s best to take your Ford to a trusted mechanic. They will be able to properly diagnose and repair the problem.
Other OBD Codes Related to P0713
“Are there other OBD codes that might be related to P0713?”
Yes, a few other OBD codes can be associated with transmission fluid temperature sensor issues. These codes include:
- P0715: Transmission Fluid Temperature Sensor/Switch ‘A’ Circuit High Input
- P0716: Transmission Fluid Temperature Sensor/Switch ‘A’ Circuit Low Input
These codes can provide additional information about the specific issue with the circuit.
What To Do After Repairing P0713
“What should I do once the problem is fixed?”
After repairing the issue, clear the code using your OBD2 scanner. Then, take your Ford for a test drive and ensure the check engine light remains off. If it returns, it means the problem hasn’t been resolved and further diagnostics are necessary.
Frequently Asked Questions About Ford OBD Code P0713
“I have some more questions about P0713. Can you answer them?”
“Can I drive my Ford with the P0713 code?”
While it’s possible to drive your Ford with a P0713 code, it’s not recommended. The code indicates a problem with the transmission fluid temperature sensor, which is vital for proper transmission operation. Driving with a faulty sensor could cause further damage to your transmission and lead to costly repairs down the line.
“What are the symptoms of P0713?”
Besides the check engine light, other symptoms of a P0713 code can include:
- Rough shifting: You may notice that your transmission is not shifting smoothly.
- Delayed shifting: The transmission may hesitate to shift into the desired gear.
- Transmission slipping: The transmission may feel like it is slipping or not engaging properly.
“How much does it cost to fix P0713?”
The cost of repairing a P0713 code can vary depending on the cause of the issue and the location of the repair. Replacing the transmission fluid temperature sensor is typically a relatively inexpensive repair. However, if the wiring needs to be repaired or the TCM is faulty, the cost will be higher.
