P0715 Input/Turbine Speed Sensor "A" Circuit
Transmission
P0715 means the transmission isn't getting a usable input (turbine) speed sensor signal, which can cause harsh shifts or limp mode.
The transmission computer isn't getting a usable signal from the input (turbine) speed sensor, which it needs to time shifts and detect slipping.
The transmission may shift harshly or go into limp mode (stuck in one gear). Drive gently and get it fixed soon.
Common causes
- A failed input speed sensor
- Damaged wiring or a corroded connector
- Metal debris on the sensor tip
- Internal transmission problems (less common)
Symptoms
- Harsh or erratic shifts
- Limp mode
- Speedometer problems on some vehicles
What to check first
- Check the transmission fluid level and condition.
- Inspect the sensor's connector and wiring.
- Watch input speed with a scan tool; it should read close to engine speed in gear with the converter locked.
- Replace the sensor if wiring is good.
