How to Resolve Error P0722 – Output Speed Sensor Range/Performance

As a car enthusiast and DIY expert, I understand the frustration that comes with encountering car problems. One common issue many drivers face is the Error P0722 – Output Speed Sensor Range/Performance.

In this article, I will provide you with a step-by-step guide on how to resolve this error and get your vehicle back on the road.

What is Error P0722?

Error P0722 refers to a fault in the output speed sensor’s range or performance. The output speed sensor is responsible for monitoring the speed of the vehicle and transmitting this information to the engine control module (ECM). When this sensor malfunctions or fails, it can trigger the P0722 error code.

Symptoms of Error P0722:

  • Illuminated Check Engine Light (CEL)
  • Issues with the transmission, such as erratic shifting or slipping
  • Speedometer not working correctly
  • Harsh or delayed shifting

Common Causes of Error P0722:

  1. Faulty wiring or connectors: Damaged or loose connections can disrupt the signal between the output speed sensor and the ECM.
  2. Malfunctioning output speed sensor: Over time, the sensor may become worn out or damaged, leading to inaccurate readings or complete failure.
  3. ECM issues: In some cases, the error may be caused by a problem with the engine control module itself.

DIY Steps to Resolve Error P0722:

Step 1: Check the Wiring

Start by inspecting the wiring and connectors associated with the output speed sensor. Ensure that all connections are secure and free from any corrosion or damage. Repair or replace any faulty wiring as necessary. This step will help rule out any electrical issues that could be causing the error.

Step 2: Inspect the Output Speed Sensor

Locate the output speed sensor, usually positioned on the transmission housing. Carefully examine the sensor for any signs of physical damage or fluid leaks. Clean the sensor using an appropriate cleaner and a soft cloth. Ensure it is properly aligned and securely mounted.

Step 3: Replace the Output Speed Sensor

If the sensor shows signs of wear or damage, it is advisable to replace it. Consult your vehicle’s service manual to locate the specific sensor and follow the manufacturer’s instructions for removal and installation. Use genuine replacement parts to ensure compatibility and optimal performance.

Step 4: Clear the Error Codes

Once the new sensor is installed, it’s essential to clear the error codes from the ECM. To do this, you can use an OBD-II scanner or disconnect the battery for a few minutes. Clearing the codes will reset the ECM and allow it to relearn the new sensor’s data.

Step 5: Test the Vehicle

After resolving the error, start the engine and take the vehicle for a test drive. Monitor the transmission’s performance, shifting behavior, and speedometer readings. Ensure that the error code does not reappear. If the error persists, further diagnostics may be required.

Tips to Prevent Error P0722:

  • Regularly inspect and maintain your vehicle’s wiring and connectors to avoid potential issues.
  • Follow the manufacturer’s recommended maintenance schedule to ensure the longevity of your output speed sensor.
  • Be mindful of any sudden changes in transmission behavior or speedometer readings and address them promptly.


By following the steps outlined in this guide, you can resolve the Error P0722 related to the output speed sensor.

Remember to exercise caution and refer to your vehicle’s service manual for specific instructions. Taking the DIY approach not only saves you money but also empowers you to tackle car issues confidently. Keep your vehicle in top shape and enjoy a smooth and trouble-free driving experience.
