How to Resolve P0710: Transmission Range Sensor Circuit Intermittent

If you’ve encountered the P0710 trouble code in your vehicle, it’s important to address it promptly to ensure the smooth operation of your transmission system.

The P0710 code refers to a “Transmission Range Sensor Circuit Intermittent” fault. This issue can affect the performance and reliability of your vehicle, but with the right knowledge and guidance, you can resolve it on your own.

Understanding the Transmission Range Sensor (TRS)

The Transmission Range Sensor (TRS), also known as the Neutral Safety Switch or the PRNDL switch, plays a crucial role in the proper functioning of your vehicle’s transmission system.

It is responsible for detecting the position of the gear selector and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate gear for smooth shifting and other transmission operations.

The TRS is usually located on the side of the transmission case, where it can easily detect the position of the gear selector. It consists of multiple electrical contacts or switches that correspond to different gear positions, such as Park (P), Reverse (R), Neutral (N), Drive (D), and so on.

Symptoms of a Faulty TRS

When the TRS starts to malfunction, it can lead to various symptoms that indicate a potential problem. Some common signs of a faulty TRS include:

  1. Intermittent or inaccurate gear shifting: The transmission may not shift smoothly or may shift into the wrong gear unexpectedly.
  2. Engine stalling: The engine may stall when shifting gears or when coming to a stop.
  3. Difficulty starting the vehicle: The engine may not start if the TRS fails to detect the correct gear position.
  4. Loss of power or acceleration: The vehicle may experience a loss of power or acceleration due to incorrect gear selection.
  5. Illuminated Check Engine Light: The P0710 trouble code will trigger the Check Engine Light on the dashboard.

If you notice any of these symptoms, it’s crucial to diagnose and resolve the issue promptly to prevent further damage to your transmission system.

Diagnostic Process

To diagnose a P0710 trouble code accurately, you’ll need to follow a systematic approach. Here are the steps involved in the diagnostic process:

  1. Step 1: Gather the necessary tools and safety precautions: Before you start diagnosing the TRS, make sure you have the required tools such as a multimeter, wiring diagram, and safety equipment like gloves and safety glasses.
  2. Step 2: Locate the TRS and inspect for any visible damage: The TRS is typically located on the side of the transmission case or the shift linkage. Inspect the sensor for any signs of physical damage, corrosion, or loose connections.
  3. Step 3: Check the electrical connections and wiring: Ensure that the electrical connectors leading to the TRS are properly connected and free from dirt or corrosion. Inspect the wiring for any signs of damage or fraying.
  4. Step 4: Test the TRS using a multimeter: Use a multimeter to measure the resistance across the terminals of the TRS. Refer to the vehicle’s service manual for the specific resistance values for each gear position. If the readings are outside the specified range, it indicates a faulty TRS.
  5. Step 5: Replace the faulty TRS if necessary: If the TRS fails the resistance test or shows visible signs of damage, it’s recommended to replace it with a new one. Follow the manufacturer’s instructions for removing and installing the TRS accurately.
  6. Step 6: Clear the trouble code and perform a test drive: After replacing the TRS, clear the trouble code using a scan tool or by disconnecting the battery for a few minutes. Take the vehicle for a test drive to ensure the P0710 code does not reappear and that the transmission is shifting smoothly.

Tips for Successful Troubleshooting

When troubleshooting a faulty TRS, keep the following tips in mind for a successful resolution:

  • Follow the correct diagnostic procedures: It’s essential to follow the recommended diagnostic procedures outlined in the vehicle’s service manual to avoid any errors.
  • Take safety precautions: Always wear appropriate safety equipment and disconnect the battery before working on electrical components.
  • Double-check electrical connections: Ensure that all electrical connections are secure and free from dirt or corrosion.
  • Use OEM or high-quality replacement parts: When replacing the TRS, use original equipment manufacturer (OEM) or high-quality aftermarket parts to ensure proper compatibility and reliability.
  • Document your steps: Keep a record of the steps you followed during the diagnostic process. This documentation can be helpful for future reference or if you need to seek assistance from a professional.

Preventive Measures

To avoid encountering TRS-related issues in the future, consider the following preventive measures:

  1. Regular maintenance: Follow the manufacturer’s recommended maintenance schedule for your vehicle, including transmission fluid changes and inspections.
  2. Inspect for signs of wear: Periodically inspect the TRS and its wiring for signs of wear, damage, or corrosion. Address any issues promptly.
  3. Avoid harsh shifting: Practice smooth and gentle shifting to reduce stress on the TRS and the entire transmission system.

By implementing these preventive measures, you can minimize the chances of experiencing a faulty TRS and ensure the long-term reliability of your vehicle’s transmission system.


Resolving the P0710 trouble code related to the Transmission Range Sensor Circuit Intermittent can be accomplished by following a systematic diagnostic process. By understanding the role of the TRS, recognizing the symptoms of a faulty sensor, and utilizing proper troubleshooting techniques, you can address the issue and restore the smooth operation of your transmission. Remember to take safety precautions, document your steps, and consider preventive measures to avoid future problems.


Q: Can I drive my vehicle with a faulty TRS?

A: It’s not recommended to drive your vehicle with a faulty TR

RS. A faulty TRS can cause issues with gear shifting, engine stalling, and loss of power. It’s best to address the problem promptly to prevent further damage to your transmission system.

Q: Can I replace the TRS myself, or should I seek professional help?

A: If you have some experience with automotive repairs and the necessary tools, you can replace the TRS yourself. However, if you’re unsure or uncomfortable with the process, it’s advisable to seek professional help to ensure the job is done correctly.

Q: Are there any alternative causes for the P0710 trouble code?

A: While a faulty TRS is a common cause of the P0710 code, there could be other factors contributing to the issue. It’s important to perform a thorough diagnostic process to rule out any other potential causes, such as wiring issues or problems with the ECM.

Q: What should I do if I’ve replaced the TRS, but the P0710 code persists?

A: If you’ve replaced the TRS and the P0710 code continues to appear, it’s recommended to recheck the wiring connections and perform further diagnostic tests. There might be an underlying issue, such as a wiring harness problem or a malfunctioning ECM, that requires further investigation.

Remember, if you’re unsure about any aspect of the diagnostic or repair process, it’s always wise to consult a qualified professional for assistance. Resolving the P0710 trouble code and ensuring the proper functioning of your transmission system is crucial for a smooth and reliable driving experience.
