How to Correct P0716 Input/Turbine Speed Sensor A Circuit Range/Performance
To correct the P0716 error code related to the Input/Turbine Speed Sensor A Circuit Range/Performance, there are several steps you can take. Here are some recommended troubleshooting and correction methods:
- Start by replacing the faulty input or output speed sensor. These sensors are responsible for monitoring the rotation speed of the input and output shafts of the transmission. If either sensor is malfunctioning or sending incorrect signals, it can trigger the P0716 error code. Replacing the faulty sensor can help resolve the issue.
- If the transmission fluid is dirty or contaminated, it can cause erratic sensor readings and trigger the error code. In such cases, it may be necessary to rebuild the transmission or flush the fluid to ensure optimal performance. Clean transmission fluid is essential for accurate sensor readings and smooth shifting.
- In addition to sensor issues and fluid contamination, faulty wiring or corroded connections can also contribute to the P0716 error code. Ensure that all wiring and connections related to the input/turbine speed sensor are inspected for damage or corrosion. Repair or replace any faulty components to restore proper functionality.
- If the aforementioned steps do not resolve the issue, it may be necessary to replace other faulty circuits or components that can affect the input/turbine speed sensor’s performance. These can include the engine coolant temperature sensor or the powertrain control module. Consult a professional mechanic or refer to the vehicle’s service manual for guidance on component replacement.
By following these steps, you can effectively correct the P0716 error code related to the Input/Turbine Speed Sensor A Circuit Range/Performance. Remember to always prioritize safety and consult with a qualified automotive professional if you encounter any difficulties during the troubleshooting or correction process.

Easy Diagnosis of Engine Error OBD Code P0716
Diagnosing the P0716 engine error code can be a straightforward process with the right tools and knowledge. By following a few steps, you can quickly identify the issue and take appropriate action.
To begin the diagnosis, you will need to connect an OBD II scan tool to your car’s diagnostic port. This device will communicate with the car’s computer system and retrieve the error code P0716. The scan tool will display the exact details of the error, including any other related codes or information.
Once you have retrieved the error code, it’s essential to check the transmission fluid level and condition. Low or contaminated fluid can sometimes trigger the P0716 code, so it’s crucial to inspect the fluid for any signs of degradation or impurities.
If the code persists after checking the fluid, the next step is to check for ground signals and reference voltage at the input speed sensor. This can be done using a digital multimeter, which measures electrical signals. By testing the wiring and circuits connected to the input speed sensor, you can identify any damaged wires or faulty connections that may be causing the error code.
It’s important to note that one common mistake when diagnosing the P0716 code is to automatically assume that a faulty speed sensor is the only cause. While a faulty speed sensor can indeed trigger the code, it’s essential to thoroughly inspect other possible causes as well.
Some other potential causes include:
- Contaminated or dirty transmission fluid
- Damaged or corroded wiring
- Faulty transmission shift solenoid
- Faulty engine coolant temperature sensor
By investigating these potential causes alongside the input speed sensor, you can ensure a comprehensive diagnosis and address all possible issues contributing to the P0716 error code.
| Possible Causes | Action |
|---|---|
| Faulty input speed sensor | Replace the faulty sensor |
| Contaminated or dirty transmission fluid | Flush and replace the transmission fluid |
| Corroded or damaged wiring connections | Repair or replace the wiring connections |
| Faulty transmission shift solenoid | Replace the faulty solenoid |
| Faulty engine coolant temperature sensor | Replace the faulty sensor |
By following these diagnosis steps and addressing each potential cause, you can successfully identify and resolve the P0716 error code and restore your car’s optimal performance.
Conclusion
The P0716 error code related to the input/turbine speed sensor circuit range/performance can have significant implications for the overall performance of your vehicle’s transmission. Ignoring this code can lead to various symptoms such as harsh shifting, engine misfires, or even stalling. Therefore, it is crucial to diagnose and address this code promptly to prevent further damage and costly repairs.
When faced with the P0716 error code, the first step is to identify the specific cause. This can involve inspecting and replacing faulty sensors, repairing wiring or connections, and ensuring the transmission fluid is clean and at the correct level. Additionally, replacing components like the engine coolant temperature sensor may be necessary.
While some DIY repairs may be possible, seeking professional assistance is recommended for accurate diagnosis and proper repairs. A qualified mechanic will have the expertise and tools to identify the underlying issue and provide effective solutions. Alternatively, you may consider the option of permanently removing the code by uploading the Engine Control Unit (ECU) file to a portal, provided the root cause has been addressed.
