BMW Code P0716 is a diagnostic trouble code (DTC) associated with the input turbine/speed sensor circuit range/performance. When the engine starts and the vehicle speed sensor indicates more than 1 mph, the DME detects the Transmission Vehicle Speed Sensor signals are erratic or missing over a certain period of time, this could be a sign of the BMW Code P0716. This code can be caused by a variety of issues, such as an open TVSS signal circuit, TVSS signal shorted to chassis ground, TVSS signal shorted to sensor ground, or a damaged or failed TVSS assembly. Understanding the underlying cause of the code can help you troubleshoot and repair the issue.
Causes and Solutions for BMW Code P0716
| Causes | Solutions |
|---|---|
| TVSS signal circuit open | Check for open circuit or connection issue |
| TVSS signal shorted to chassis ground | Measure resistance between the circuit ground and chassis ground |
| TVSS signal shorted to sensor ground | Check the sensor ground and sensor circuit wiring |
| TVSS assembly is damaged or failed | Replace the TVSS assembly |
When a BMW vehicle displays the Code P0716, it means that the input turbine/speed sensor circuit range/performance is not within the normal range. This code can be caused by an open TVSS signal circuit, a TVSS signal shorted to chassis ground, a TVSS signal shorted to sensor ground, or a damaged or failed TVSS assembly. Fortunately, troubleshooting and repairing the issue is relatively straightforward. By understanding the underlying cause of the code, you can take the necessary steps to fix the issue, ensuring that your BMW is running smoothly.
Open TVSS Signal Circuit
When the TVSS signal circuit is open, it is unable to communicate with the engine control module (ECM). This can cause the DME to detect that the TVSS signals are erratic or missing, resulting in the BMW Code P0716. To fix this issue, you must check for any open circuits or connection issues.
TVSS Signal Shorted to Chassis Ground
When the TVSS signal is shorted to chassis ground, it will cause the ECM to be unable to receive signals from the sensor. To troubleshoot this issue, you must measure the resistance between the circuit ground and chassis ground. If the resistance is low, this indicates that the signal is shorted to ground.
TVSS Signal Shorted to Sensor Ground
When the TVSS signal is shorted to the sensor ground, it will cause the DME to detect that the TVSS signals are erratic or missing. To fix this issue, you must check the sensor ground and sensor circuit wiring. If any of the wiring is damaged or disconnected, it must be replaced or reconnected in order to resolve the issue.
Damaged or Failed TVSS Assembly
If the TVSS assembly is damaged or failed, it will cause the DME to detect that the TVSS signals are erratic or missing, resulting in the BMW Code P0716. To fix this issue, you must replace the TVSS assembly.
Conclusion
The BMW Code P0716 is an error code that indicates that the input turbine/speed sensor circuit range/performance is not within the normal range. This code can be caused by an open TVSS signal circuit, a TVSS signal shorted to chassis ground, a TVSS signal shorted to sensor ground, or a damaged or failed TVSS assembly. Fortunately, troubleshooting and repairing the issue is relatively straightforward. By understanding the underlying cause of the BMW Code P0716, you can take the necessary steps to fix the issue, ensuring that your BMW is running smoothly.
