The P0716: Input/Turbine Speed Sensor A Circuit Range/Performance refers to an issue where the input/turbine speed sensor A is not functioning within the expected range or performance. This sensor measures the speed of the transmission turbine, and if it fails to work correctly, it may cause incorrect data to be sent to the transmission control module (TCM), leading to shifting issues.
P0716 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0716: Input/Turbine Speed Sensor A Circuit Range/Performance |
| Is it serious? | Yes, as improper turbine speed readings can lead to shifting problems and poor transmission performance. |
| Possible causes | – Range or performance issue with input/turbine speed sensor A – Faulty sensor – Wiring issues |
| How to diagnose? | – Test the sensor for range and performance – Inspect wiring and connectors – Replace sensor if performance is out of range |
P0716 Meaning
The P0716 code is triggered when the input/turbine speed sensor A is not reading or performing within the expected range. This sensor is crucial for detecting the rotational speed of the transmission’s turbine, allowing the TCM to adjust shifting patterns accordingly. A malfunction in this sensor can cause poor shifting and transmission inefficiency.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other transmission-related codes that may help diagnose the problem with the input/turbine speed sensor. | OBD-II Scanner |
| Test the Sensor for Range and Performance | Use a multimeter or diagnostic tool to test the input/turbine speed sensor A for proper operation. Compare the readings to manufacturer specifications to ensure the sensor is working within its performance range. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connectors | Visually inspect the wiring and connectors associated with the input/turbine speed sensor for signs of damage, loose connections, or corrosion. | Flashlight, Multimeter |
| Check Sensor Alignment | Ensure that the input/turbine speed sensor is properly aligned and securely mounted, as misalignment can cause inaccurate readings. | Basic Tools |
| Replace the Sensor if Necessary | If the sensor is found to be faulty or performing outside the expected range, replace it to restore proper transmission speed monitoring. | Replacement Parts, Standard Tools |
| Clear Code and Retest | After repairs, clear the P0716 code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0716 code has not returned. | OBD-II Scanner |
