What P0715 means
The input or turbine shaft speed sensor – a Hall sensor with square-wave output or an inductive sensor with sine output – reports the speed behind the torque converter. With output and engine speed it gives the actual gear ratio, converter slip and shift timing. P0715 is the general circuit code. Ford uses it for 'no signal' too: the vehicle is moving under power (engine above converter stall speed, output speed plausible) but the sensor reports under 200 rpm for 5–30 s; Ford's DPS6 dual-clutch sets it for a hardware-detected fault of input shaft sensor 1. Subaru-based systems flag an open or shorted circuit, Saab's Aisin box no input signal while the output sensor works, substituting output speed. GM does not use P0715. Limp mode, harsh shifts and a disabled converter clutch follow.
P0715 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0715
- Check engine and/or transmission warning lamp
- Limp mode with fixed gear, harsh shifts
- Torque converter clutch does not apply
- Input speed shows 0 or implausible in the scan tool
Common causes of P0715
- Most likelySpeed sensor faulty (Hall IC or coil open or shorted)
- Most likelyConnector or harness corroded, chafed or loose pins (with internal sensors also the pass-through connector)
- PossibleMetal debris on the sensor magnet or damaged reluctor wheel
- Less likelyTransmission module or its sensor supply faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0715 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 15 | The exact fault in that area. |
What to do next
- Note P0715 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0715
What does P0715 mean?
P0715 means "Input/Turbine Shaft Speed Sensor A Circuit". The input or turbine shaft speed sensor – a Hall sensor with square-wave output or an inductive sensor with sine output – reports the speed behind the torque converter. It is a generic code, so it means the same on every make.
Is it safe to drive with P0715?
Drive gently and only to a workshop. With P0715 the car can go into limp mode (reduced power) to protect itself.
Will P0715 fail an emissions test?
Yes, it can. P0715 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0715 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0715 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
