P0715 Input/turbine speed sensor circuit

Needs attention Have it looked at soon. The car is usually driveable with care in the meantime.

What does P0715 mean?

P0715 is a generic powertrain code, defined by the SAE standard, so it means the same thing on every make and model: input/turbine speed sensor circuit. It belongs to the transmission group of codes.

A control module stores the code when something it watches stays outside what it expects for long enough. On its own the code says which system complained, not which part has failed — the causes below, most likely first, are where to start.

Is it safe to drive with P0715?

Needs attention. Drive gently and have the gearbox checked.

Common causes of P0715

Failed input speed sensor.
Wiring fault.
Low transmission fluid.

Symptoms

Erratic shifting.
Speedometer or gear display errors.
Limp mode.

What to check first

Sensor signal.
Fluid level.
Harness at the gearbox.

Can I just clear P0715?

You can, and the light goes out — but a fault that is still there sets the code again, often within a drive or two. Clearing also erases the freeze frame (what the engine was doing when the code was stored) and resets the emissions readiness monitors, so an MOT, smog or inspection test will wait until they have run again. Fix the cause first, then clear it, then watch whether it returns.

Read and clear P0715 from your iPhone with OBDTrip

Plug a Bluetooth OBD-II adapter into the car and OBDTrip reads every stored, pending and permanent code, explains each one in plain English like this, shows what the engine was doing when it was set, and clears the check engine light once the fault is fixed. It keeps a history of when each code comes back, and records every drive on its own from then on.

Needs a Bluetooth Low Energy adapter such as the Vgate iCar Pro — which adapters work with iPhone. Reading and clearing codes is part of an OBDTrip subscription.
