Subaru Code P0715

If your Subaru has been throwing the code P0715, chances are you have a problem with the Torque Converter Turbine Speed Sensor Circuit. This code is triggered when the powertrain control module (PCM) can’t detect any signals from the Torque Converter Turbine Speed sensor during the continuous test. The issue can be caused by a variety of factors, ranging from faulty wiring and electrical connections to a broken component. To help diagnose the issue, it is important to understand the causes and solutions for the P0715 Subaru code.

Causes and Solutions for the Subaru Code P0715

Cause Solution
Faulty wiring or electrical connections Check the wiring and connections for damage
Broken component Replace the broken component
Faulty transmission fluid Change the transmission fluid
Faulty PCM Replace the PCM

Faulty Wiring and Electrical Connections

The most common cause of Subaru Code P0715 is a faulty wiring or electrical connections. When these connections have become damaged or disconnected, the PCM is unable to detect any signals from the Torque Converter Turbine Speed sensor. To diagnose this issue, it is important to check all the wiring and connections for any damage or loose connections. If any damage is found, it should be repaired or replaced to restore the connection.

Broken Component

Another possible cause of the P0715 Subaru code is a broken component. This can be caused by several different factors, including wear and tear, excessive heat, or poor maintenance. If any of these issues are present, then it will be necessary to replace the broken component.

Faulty Transmission Fluid

Faulty transmission fluid can also cause the Subaru Code P0715. If the transmission fluid has become contaminated or has begun to break down, then it will not be able to properly lubricate the components in the transmission. In this case, it will be necessary to replace the transmission fluid to restore the proper lubrication.

Faulty PCM

Finally, the P0715 Subaru code can be caused by a faulty PCM. If the PCM has become damaged or corrupted, then it will not be able to send the necessary signals to the Torque Converter Turbine Speed sensor. In this case, it will be necessary to replace the PCM in order to restore the connection.

Conclusion

The Subaru Code P0715 can be caused by a variety of different factors, ranging from faulty wiring and electrical connections to a broken component or faulty transmission fluid. It is important to determine the cause of the issue and then take the necessary steps to repair it. To help diagnose and repair the issue, it is important to understand the causes and solutions for the Subaru Code P0715.
