How to Fix P0713 – Transmission Fluid Temperature Sensor Circuit Low Input

Are you experiencing issues with your vehicle’s transmission? Is the check engine light illuminated on your dashboard? One potential culprit could be the P0713 trouble code, which indicates a low input in the transmission fluid temperature sensor circuit. In this guide, we’ll walk you through the process of fixing the P0713 error and getting your vehicle back on the road.

1. Introduction

The transmission fluid temperature sensor plays a crucial role in monitoring the temperature of the transmission fluid. It provides essential data to the vehicle’s engine control module (ECM) to ensure optimal performance and prevent damage to the transmission system. When the sensor detects a low input, it triggers the P0713 error code.

2. Understanding the P0713 Trouble Code

The P0713 trouble code specifically relates to the transmission fluid temperature sensor circuit. It indicates that the input voltage is below the normal range, suggesting a potential issue with the sensor or its wiring. If left unresolved, this problem can lead to further transmission complications and potential damage.

3. Symptoms of a P0713 Error

When the P0713 error code is triggered, you may experience the following symptoms:

car vertical
  • Illumination of the check engine light
  • Transmission shifting issues or erratic shifting
  • Poor fuel efficiency
  • Transmission overheating
  • Reduced power and performance

If you notice any of these signs, it’s crucial to address the issue promptly to prevent further damage and ensure your safety on the road.

4. Causes of P0713 Error

The P0713 error code can be caused by various factors, including:

  • Faulty transmission fluid temperature sensor
  • Damaged or frayed wiring in the sensor circuit
  • Loose connections or poor electrical contacts
  • Issues with the ECM or related components
  • Electrical shorts or open circuits

Identifying the underlying cause is essential for an effective repair.

5. Preparing for the Fix

Before diving into the repair process, it’s important to gather the necessary tools and materials. Here’s a list of what you’ll need:

  • Safety gloves and goggles
  • Jack and jack stands
  • Socket set
  • Torque wrench
  • Multimeter
  • Replacement transmission fluid temperature sensor
  • Wire connectors and electrical tape

Having these items on hand will ensure a smooth and efficient repair process.

6. Step 1: Safety Precautions

Safety should always be your top priority when working on a vehicle. Begin by parking your car on a level surface and engaging the parking brake. It’s also advisable to wear safety gloves and goggles to protect yourself from any potential hazards.

7. Step 2: Locating the Transmission Fluid Temperature Sensor

The transmission fluid temperature sensor is typically located on or near the transmission housing. Consult your vehicle’s service manual or do a quick online search to find the exact location for your specific make and model. Once located, ensure the engine is cool before proceeding with the repair.

8. Step 3: Removing the Sensor

To begin the repair, disconnect the negative terminal of the battery to prevent any electrical mishaps. Then, carefully disconnect the wiring harness from the sensor. Depending on your vehicle, you may need to remove other components or protective covers to access the sensor properly.

9. Step 4: Inspecting the Sensor

With the sensor removed, carefully inspect it for any visible signs of damage or corrosion. Check the electrical connectors and wires for any wear or fraying. If you notice any issues, it’s advisable to replace the sensor entirely.

10. Step 5: Replacing the Sensor

Install the new transmission fluid temperature sensor by reversing the removal process. Ensure that the sensor is securely in place and reconnect the wiring harness. Double-check all connections to guarantee proper installation.

11. Step 6: Testing and Verifying the Fix

After the sensor replacement, it’s essential to test the fix and verify its effectiveness. Reconnect the negative terminal of the battery and start the engine. Use a multimeter to measure the voltage output from the sensor and compare it to the manufacturer’s specifications. If the readings are within the correct range, the fix was successful.

12. Tips for a Successful Fix

  • Always consult your vehicle’s service manual for specific instructions and torque specifications.
  • Take pictures or label wires during disassembly to ensure correct reinstallation.
  • Use dielectric grease on electrical connectors for improved conductivity and protection against moisture.
  • Perform a transmission fluid change if the fluid appears contaminated or has not been replaced for an extended period.

13. Preventive Measures

To prevent future occurrences of the P0713 error code, consider these preventive measures:

  • Regularly inspect and clean the transmission fluid temperature sensor.
  • Check the wiring and connectors for any signs of wear or damage.
  • Maintain proper transmission fluid levels and adhere to the recommended service intervals.
  • Avoid driving aggressively or overloading the vehicle, as it can lead to excessive transmission heat.

14. Conclusion

Fixing the P0713 error code related to the transmission fluid temperature sensor circuit is a task that can be accomplished with basic mechanical knowledge and the right tools. By following the steps outlined in this guide, you can diagnose and repair the issue, ensuring the longevity and performance of your vehicle’s transmission system.
