P0715: Input / turbine speed sensor circuit malfunction
Drive carefully. Get it checked within a week or two.
Can I drive with P0715?
Yes, but drive carefully and get it checked soon. Transmission cannot measure input shaft RPM, resulting in harsh gear shifts or limp mode.
What does P0715 mean?
P0715 stands for Input/Turbine Speed Sensor Circuit Malfunction.
Symptoms you may notice
- Transmission locked in 3rd gear limp mode (won't shift up or down)
- Harsh clunking sound when shifting into Drive or Reverse
- Engine revs high without vehicle accelerating (slipping gear)
How much does it cost to fix?
Repair costs for code P0715 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:
- Defective input speed sensor
- Corroded wiring plug on transmission housing
- Metallic debris coating magnetic sensor tip
- Internal transmission damage
What to do next
- Check transmission fluid for burnt odor or metallic sparkles.
- Inspect sensor wiring harness on the transmission case.
- Replace the input speed sensor.

About this code
Code P0715 means the TCM lost input speed readings from the torque converter turbine. Without this speed reference, the computer cannot time clutch engagement smoothly, triggering harsh 'clunking' shifts or locking the transmission in 3rd gear. Safe for a cautious drive to the shop.
