P0715 2018 Toyota RAV4 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 2018 Toyota RAV4 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 2018 Toyota RAV4?
- 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 2018 Toyota RAV4 Code
1. What does the OBDII code P0715 mean for a 2018 Toyota RAV4?
P0715 indicates a malfunction in the input/turbine speed sensor circuit, which monitors the transmission's input shaft speed and helps the vehicle's control module manage gear shifting.
2. What are the common symptoms of code P0715 in a 2018 Toyota RAV4?
Symptoms may include erratic shifting, delayed gear engagement, transmission slipping, reduced fuel efficiency, and the Check Engine Light being illuminated.
3. What causes the P0715 code to appear on a 2018 Toyota RAV4?
Common causes include a faulty input/turbine speed sensor, wiring issues such as damaged or corroded connections, a malfunctioning transmission control module (TCM), or internal transmission problems.
4. How can I diagnose the P0715 code on my 2018 Toyota RAV4?
Use an OBDII scanner to confirm the code, visually inspect the wiring and connectors for damage, test the input speed sensor with a multimeter, and check for other related codes that might indicate additional issues.
5. Can I still drive my 2018 Toyota RAV4 with a P0715 code?
While the vehicle might still be drivable, it is not recommended as the transmission may not operate properly, potentially leading to further damage or unsafe driving conditions.
6. How do you fix the P0715 code on a 2018 Toyota RAV4?
Repairs could involve replacing the faulty input speed sensor, repairing or replacing damaged wiring, updating or reprogramming the TCM, or addressing internal transmission issues if necessary.
7. How much does it cost to repair the P0715 code on a 2018 Toyota RAV4?
The repair cost can vary. Replacing the input speed sensor typically costs between $150 and $400, depending on parts and labor. Additional repairs like wiring fixes or transmission work will increase the cost.
8. Can low transmission fluid cause the P0715 code on a 2018 Toyota RAV4?
Low or dirty transmission fluid is not a direct cause of P0715, but poor fluid condition can lead to transmission performance issues, which might indirectly affect the input speed sensor’s readings.
9. How do I prevent the P0715 code from occurring on my 2018 Toyota RAV4?
Regularly maintain the transmission by changing the fluid as recommended, inspect electrical connections for corrosion or damage, and address transmission issues promptly.
10. Does the P0715 code mean my 2018 Toyota RAV4 needs a new transmission?
Not necessarily. The issue is often related to the speed sensor or wiring. However, if internal transmission damage is found during diagnosis, more extensive repairs may be required.
