P0715 Code: Input/Turbine Speed Sensor Circuit Malfunction
🟠 Moderate severity · drivable
Drivable, but shifting may be harsh and erratic. Fix it soon to avoid transmission damage.
What P0715 means
The input (turbine) speed sensor circuit has a fault, so the computer can't read the transmission's input shaft speed. This sensor helps the computer control shift timing.
Symptoms
- Check engine light is on
- Harsh or erratic shifting
- Transmission may enter limp mode
Common causes
- most common: Faulty input speed sensor
- common: Low or dirty transmission fluid
- common: Damaged wiring or loose connector
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check the transmission fluid level and condition | Yes | $20–60 |
| Replace the input speed sensor | Mechanic | $100–300 |
