What is P0715 fault code? What is the description of the Input/TurbineSpeed Sensor A Circuit malfunction How can I fix P0715 fault code What are the causes of the P0715 fault codes?
What is the P0715 fault code?
There are many sensors on your vehicle that monitor the various components of your engine and transmission. These sensors communicate continuously with the vehicle’s host computer (Powertrain Control Module/PCM/ECM) in order to ensure vehicle operation.
Fault code P0715 refers to the transmission and engine communication. The code P0715 is triggered when the PCM detects an error in the signal from the transmission’s input speed sensor. This happens because the engine speed (turbine speed) cannot be read to determine shifting. Circuit “A”, which indicates the input speed sensors.
The turbine speed sensor is located in or inside your vehicle’s transmission and measures the rotation of the turbine shaft. If the PCM/TCM (transmission controller module) detects an error in the turbine speed input, the check engine lamp will light up.
This malfunction may cause the vehicle to switch to Limp Mode. Limp mode means that the vehicle’s speed and power are reduced to prevent any further damage to other parts. This mode causes the automatic transmission to only stay in 2nd and 3rd gear.
What is the P0715 Fault Code?
- – Defective inlet/turbine speed sensor
- – Defective output speed sensor
- Faulty or damaged speed sensor wiring
- Faulty speed sensor electric connection
- – Defective shift solenoids
- – Transmission valve body damaged
- – Defective torque converter
- – Broken or damaged reluctor ring/shaft
- – Low or dirty transmission oil
- – Defective PCM
What are the symptoms for P0715 malfunction code?
Failure or erratic shifting problems are the most common symptoms of a P0715 Code.
- – Illumination for check engine light
- – Hard and erratic shifting issues
- – The vehicle can be switched to protection mode (Limp Mod)
- Fluctuations of speedometer
- – Increased fuel consumption
- – Sometimes the engine might stall.
How to Fix the P0715 Fault Code
Your mechanic will inspect the wiring and input velocity sensor in detail. They must be replaced if the cables are damaged. It is important to test the voltage signal from the sensor to determine if there are any faults in the wiring. The sensor should be replaced if it isn’t damaged. After that, the ECM/PCM should be reset and the vehicle checked. If the problem continues, the issue may be with the automatic transmission.
After replacing the wiring or sensors for the input speed sensor, fluid from transmission should be removed. If the sensor fails again, it could happen quickly.
- Repair of damaged wiring in the input speed sensor
- – Replacing your input speed sensor
How serious is the P0715 Fault code?
The vehicle can experience different effects from P0715. Although it is not always a serious problem, shifting problems can sometimes occur. It is dangerous to have an automatic transmission that doesn’t shift.
