What does P0715 mean on a Renault?
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.
What causes P0715 on a Renault?
Beyond the generic causes listed on the main P0715 page, these are the Renault-specific patterns we see most often:
Renault MeganeDP0/AL4 input speed sensor heat failure

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.

FAQ: P0715 on Renault
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.
