P0715 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.

What does P0715 mean on a Peugeot?
Peugeot 308
2007-2024The 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. Always change fluid at 60,000 km intervals.
What causes P0715 on a Peugeot?
Beyond the generic causes listed on the main P0715 page, these are the Peugeot-specific patterns we see most often:

How to diagnose P0715 on a Peugeot with OBD2
Follow these steps to pinpoint the root cause of P0715:
- 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.
- Check the input speed sensor connector for corrosion, bent pins, or loose connections. The connector is typically on the side of the transmission housing.
- Measure the sensor resistance with a multimeter (typical range 200-1500 ohms depending on manufacturer). Compare to the service manual specification for your vehicle.
- Monitor the input speed sensor signal with a scanner in live data mode while test driving. The signal should rise smoothly with vehicle speed and not drop out or show erratic readings.
- 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.

FAQ: P0715 on Peugeot
What does P0715 mean?
P0715 means the transmission's input speed sensor is not sending a reliable signal to the control module. This sensor tells the transmission how fast the input shaft is spinning, which is critical for calculating when to change gears.
Where is the input speed sensor located?
The input speed sensor is typically mounted on the outside of the transmission housing, near the bell housing where the engine meets the transmission. On some vehicles, it is inside the transmission and requires pan removal to access.
Can I drive with P0715?
Driving is not advised. The transmission may stay in limp mode or shift unpredictably. Short-distance driving to a garage at low speed is generally acceptable, but avoid motorway driving.
How much does an input speed sensor cost?
The sensor itself costs 30-150 EUR depending on the vehicle. Labour adds 80-250 EUR. It is one of the cheaper transmission repairs, especially compared to internal transmission work.
Can dirty transmission fluid cause P0715?
Yes. Contaminated fluid with metal particles can interfere with the magnetic speed sensor. A transmission fluid change may resolve the issue if the sensor itself is not damaged.
