How to Solve Error P0724 – Output Speed Sensor Intermittent

Welcome to another DIY guide for car enthusiasts! In this article, we will discuss the P0724 error code, specifically focusing on how to diagnose and fix it.

If you’ve encountered this error code and are wondering what it means and how to resolve it, you’ve come to the right place. So, let’s dive in and get your vehicle back on track!

What is the P0724 Error Code?

The P0724 error code refers to “Output Speed Sensor Intermittent.” It is a diagnostic trouble code (DTC) that indicates an intermittent issue with the output speed sensor in your vehicle’s transmission.

The output speed sensor is responsible for monitoring the rotational speed of the output shaft, providing valuable data for various systems, such as the transmission control module (TCM) and the engine control module (ECM).

Symptoms of P0724 Error Code:

When the P0724 error code is triggered, you may experience several symptoms.

These can include harsh shifting, inaccurate speedometer readings, hesitation during acceleration, stalling, and even an illuminated check engine light. It’s essential to pay attention to these symptoms and take prompt action to diagnose and resolve the issue.

Causes of P0724 Error Code:

Several factors can contribute to the P0724 error code. The most common causes include faulty output speed sensor, wiring or connection issues, problems with the transmission control module, or internal transmission malfunctions. Understanding the underlying causes will help you narrow down the potential solutions.

Diagnosing the P0724 Error Code:

To diagnose the P0724 error code, follow these step-by-step instructions:

  1. Check the transmission fluid: Ensure the transmission fluid level is adequate and inspect its condition. Dirty or low fluid levels can affect sensor readings.
  2. Inspect the wiring and connections: Examine the wiring harness and connections related to the output speed sensor. Look for any signs of damage, loose connections, or corrosion.
  3. Test the output speed sensor: Use a multimeter to measure the resistance and voltage output of the sensor. Compare the readings with the manufacturer’s specifications to determine if the sensor is faulty.
  4. Scan the vehicle for additional codes: Use an OBD-II scanner to retrieve any additional error codes present. This can provide further insight into related issues that may contribute to the P0724 code.

Fixing the P0724 Error Code:

Once you have identified the cause of the P0724 error code, you can proceed with the appropriate solution:

  1. Replace the output speed sensor: If the sensor is determined to be faulty, replace it with a new one. Ensure the replacement sensor is compatible with your vehicle’s make and model.
  2. Repair wiring or connections: If there are issues with the wiring or connections, repair or replace them as necessary. Ensure proper insulation and secure connections to prevent future problems.
  3. Address transmission control module issues: If the problem lies with the transmission control module, consult a professional mechanic or contact the manufacturer for guidance on repairing or reprogramming the module.
  4. Seek professional assistance: If the error persists or you are uncomfortable performing the diagnostics and repairs yourself, it’s best to seek the help of a qualified automotive technician.

Tips to Prevent P0724 Error Code:

To minimize the chances of encountering the P0724 error code, consider the following preventive measures:

  1. Routine maintenance: Follow the recommended maintenance schedule for your vehicle, including regular transmission fluid changes and inspections.
  2. Protect electrical connections: Ensure the electrical connections related to the output speed sensor are well-protected and free from corrosion.
  3. Handle the transmission with care: Avoid harsh driving habits, excessive towing, or overloading, as these can put additional stress on the transmission components.


Dealing with the P0724 error code can be frustrating, but with the right knowledge and approach, you can resolve it successfully. By understanding the symptoms, causes, and diagnostic procedures, you can pinpoint the issue and take appropriate steps to fix it. Remember, if you’re unsure or uncomfortable with any part of the process, it’s always wise to consult a professional. Stay proactive with preventive measures to minimize the chances of encountering the P0724 error code in the future.


Can I continue driving my vehicle with the P0724 error code?

  1. It is not recommended to drive your vehicle with the P0724 error code, as it can lead to further transmission problems and potential damage. It’s best to address the issue promptly to avoid complications.

How much does it cost to fix the P0724 error code?

  1. The cost of fixing the P0724 error code can vary depending on the underlying cause and the extent of the repairs required. It’s advisable to consult a professional mechanic or dealership to get an accurate estimate.

Can I reset the P0724 error code without fixing the issue?

  1. While you can reset the error code using an OBD-II scanner, it will not resolve the underlying problem causing the P0724 code. It’s crucial to identify and fix the root cause to prevent the error code from reoccurring.
