What Does P0715 Trouble Code Mean?
The P0715 trouble code means there’s an issue with the Input/Turbine Speed Sensor in your vehicle’s transmission.
This sensor plays a crucial role in measuring the speed of the transmission’s input shaft, which directly affects how your car shifts gears.
When the sensor sends incorrect or no data to the Engine Control Module (ECM), the ECM can’t manage the transmission’s operation properly.
This trouble code often triggers the Check Engine Light.
It’s important to address it promptly because a malfunctioning Input/Turbine Speed Sensor can lead to rough or erratic shifting, poor fuel economy, and even transmission damage over time.
In simpler terms, the ECM relies on the data from this sensor to know how fast the transmission input shaft is spinning.
If this data is faulty, the ECM can’t control the gear shifts effectively, causing various drivability issues.
This could be due to electrical issues like damaged wires, connectors, or the sensor itself being defective.
Ignoring the P0715 code can result in more severe problems. For example, the transmission might start slipping, shifting harshly, or not shifting at all.
This can make driving unsafe and might lead to more expensive repairs if left unchecked.
In summary, the P0715 trouble code indicates a problem with the sensor that monitors the transmission input shaft’s speed.
This affects the ECM’s ability to control the transmission, leading to potential drivability issues and transmission damage.
Addressing this problem quickly can save you from bigger headaches down the road.
P0715 Trouble Code Symptoms
When the P0715 trouble code appears, you might notice several symptoms that indicate an issue with your vehicle’s transmission. Here’s what to look out for:

- Delayed shifting
- Transmission stuck in one gear
- Reduced power or performance
P0715 Trouble Code Causes
Several factors can cause the P0715 trouble code to appear. Here are the common causes:
- Faulty input/turbine speed sensor
- Damaged or corroded wiring and connectors
- Issues with the transmission fluid
- Malfunctioning Engine Control Module (ECM)
- Mechanical problems within the transmission
- Dirty or clogged transmission filter
How To Fix A P0715 Trouble Code
Fixing a P0715 trouble code involves diagnosing the root cause and addressing it. Here’s a step-by-step guide to help you through the process:
1. Scan for Codes
Use an OBD-II scanner to confirm the P0715 code and check for any additional codes that might be present.
2. Inspect Wiring and Connectors
Visually inspect the wiring and connectors related to the input/turbine speed sensor. Look for any signs of damage, corrosion, or loose connections. Repair or replace any damaged components.
3. Check the Sensor
Test the input/turbine speed sensor using a multimeter. Compare the readings to the manufacturer’s specifications. If the sensor is faulty, replace it.
4. Examine Transmission Fluid
Check the transmission fluid level and condition. Low or dirty transmission fluid can affect sensor operation. If necessary, top off or replace the transmission fluid and filter.
5. Test the ECM
If the sensor and wiring are in good condition, the issue might be with the Engine Control Module (ECM). Testing the ECM usually requires specialized equipment and may need to be done by a professional.
6. Mechanical Inspection
If all else fails, there might be a mechanical issue within the transmission itself. This can include problems with the input shaft or internal components. Consult a transmission specialist if you suspect mechanical damage.
7. Clear the Code
After performing the necessary repairs, use the OBD-II scanner to clear the trouble code. Drive the vehicle to see if the code returns. If it does, further diagnosis may be needed.
By following these steps, you can diagnose and fix the P0715 trouble code, ensuring your transmission operates smoothly again.
