P0715 on Renault: Causes, Symptoms and Fix Cost
Quick Answer

P0715 on a Renault 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.

Renault Megane
2006-2023Megane models with the DP0/AL4 automatic transmission are well-known for P0715. The input speed sensor on these transmissions fails frequently, often due to heat damage from the transmission running hot. Replacing the sensor along with fresh fluid usually resolves the issue. Consider upgrading to an improved aftermarket sensor.

How to diagnose P0715 on a Renault 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.
