P0715 on Peugeot: Causes, Symptoms and Fix Cost

Quick Answer
High SeverityNot safe to drivePeugeot

P0715 on a Peugeot means the transmission control module is not receiving a valid signal from the input speed sensor, also called the turbine speed sensor. This sensor measures how fast the transmission input shaft is spinning, which is essential for calculating proper gear changes.

Typical repair cost, all makes€100 - €1350

Connect any standard Bluetooth OBD2 adapter to your Peugeot and Skanyx tells you what P0715 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

What does P0715 mean on a Peugeot?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Peugeot models that log P0715.

Peugeot 308

2007-2024

The 308 with the AL4/DP0 and later EAT6 (Aisin TF-70SC) automatic transmissions can trigger P0715. On the AL4, the turbine speed sensor is a very common failure part. The EAT6 is more reliable but can develop sensor connector corrosion. Keep to the fluid-change interval in the service schedule; the AL4 in particular does not tolerate neglected fluid.

What causes P0715 on a Peugeot?

Beyond the generic causes listed on the main P0715 page, these are the patterns noted for Peugeot models:

How to diagnose P0715 on a Peugeot with OBD2

Follow these steps to pinpoint the root cause of P0715:

  1. Read freeze frame data and note vehicle speed, engine RPM, and transmission temperature when the code was set. This helps determine if the failure is intermittent or constant.
  2. Check the input speed sensor connector for corrosion, bent pins, or loose connections. The connector is typically on the side of the transmission housing.
  3. Measure the sensor resistance with a multimeter (typical range 200-1500 ohms depending on manufacturer). Compare to the service manual specification for your vehicle.
  4. Monitor the input speed signal while test driving. Transmission input speed is not standard OBD2 live data on most cars, so this needs manufacturer-level software. The signal should rise smoothly with vehicle speed and not drop out or show erratic readings.
  5. If the sensor and wiring test good, check the transmission fluid condition. Metal debris from internal wear can interfere with the magnetic sensor and cause false readings.
