P0715 Toyota Code - Input / Turbine Speed Sensor Circuit Malfunction
Quick Answer
The Input Speed sensor detects the rotation speed of the turbine which indicates the input speed of the transaxle. Common causes include Faulty Transmission Speed Sensor NT (Transmission Revolution Sensor), Transmission Speed Sensor harness is open or shorted, Transmission Speed Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0715 Toyota Description
The NT terminal of the ECM detects a pulse signal from the speed sensor NT (input RPM). The ECM calculates gear shifts by comparing the signal from speed sensor NT with the signal from speed sensor NC.
While the transaxle is operating in 2nd, 3rd, 4th, 5th, or 6th gear with the shift lever in D, if the input shaft speed is less than 300 rpm although the output shaft speed is more than 1000 rpm, the ECM interprets this as a fault, illuminates the MIL and stores the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0715 Toyota?
- Faulty Transmission Speed Sensor NT (Transmission Revolution Sensor)
- Transmission Speed Sensor harness is open or shorted
- Transmission Speed Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P0715 Toyota Code
What does the OBDII code P0715 mean for a Toyota?
P0715 indicates a malfunction in the Input/Turbine Speed Sensor Circuit, which monitors the rotational speed of the transmission's input shaft.
What are the common symptoms of a P0715 code in a Toyota?
Symptoms may include poor acceleration, harsh or delayed shifting, transmission slipping, and the check engine light being illuminated.
What causes the P0715 code to appear in a Toyota?
Common causes include a faulty input/turbine speed sensor, damaged wiring or connectors, transmission fluid contamination, or internal transmission issues.
Can I drive my Toyota with a P0715 code?
Driving with this code is not recommended, as it can lead to further transmission damage and may impact vehicle performance and safety.
How do I diagnose the P0715 code on a Toyota?
Diagnosis typically involves inspecting the input speed sensor, checking wiring and connectors for damage, and testing the sensor's electrical signals using a multimeter.
What does an input/turbine speed sensor do?
The input speed sensor monitors the rotational speed of the transmission's input shaft to help the transmission control module (TCM) manage gear shifting.
How much does it cost to fix the P0715 code on a Toyota?
Repair costs vary but generally range from $100 to $300, depending on whether the sensor, wiring, or other components need replacement.
Can low transmission fluid cause a P0715 code on a Toyota?
Yes, low or contaminated transmission fluid can affect sensor readings and trigger the P0715 code.
How do I reset the check engine light after fixing the P0715 code on my Toyota?
You can reset the light by using an OBDII scanner or by disconnecting the battery for a few minutes, but ensure the issue is resolved first.
What happens if I ignore the P0715 code on my Toyota?
Ignoring this code can lead to worsening transmission performance, higher repair costs, and potential damage to internal transmission components.
