P07BF 2016 Toyota RAV4 Code - Input / Turbine Speed Sensor 'A' Circuit Low
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 P07BF 2016 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 P07BF 2016 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)

3. What causes the P07BF code to trigger in a Toyota RAV4?
Possible causes include a faulty turbine speed sensor, damaged wiring or connectors, a malfunctioning transmission control module (TCM), or internal transmission issues.
4. Can I still drive my 2016 Toyota RAV4 with the P07BF code?
While the vehicle may still be drivable, continuing to drive with this code can lead to further transmission damage and reduced performance. It’s best to address the issue promptly.
5. How do I diagnose the P07BF code in my Toyota RAV4?
Diagnosis involves using a scan tool to monitor the sensor's data, inspecting the wiring and connectors for damage or corrosion, and testing the sensor for proper operation.
6. How is the P07BF code fixed on a 2016 Toyota RAV4?
Repairs may include replacing the input/turbine speed sensor, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the transmission control module if needed.
7. How much does it cost to fix the P07BF code on a Toyota RAV4?
Repair costs vary but typically range from $150 to $400, depending on whether the issue is with the sensor, wiring, or TCM.
8. Can a dirty transmission fluid cause the P07BF code?
While unlikely, extremely dirty or degraded transmission fluid can contribute to transmission issues, so a fluid inspection or change may be recommended during diagnosis.
9. Where is the Input/Turbine Speed Sensor 'A' located in a 2016 Toyota RAV4?
The sensor is typically located inside the transmission housing, near the input shaft or turbine assembly.
10. Do I need to reprogram the TCM after replacing the turbine speed sensor?
In some cases, reprogramming or resetting the TCM may be necessary to clear the code and restore proper operation. Check the service manual or consult a mechanic.
