P07BF 2018 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 2018 Toyota RAV4 Description

The Input Speed sensor detects the rotation speed of the turbine which indicates the input speed of the transaxle. By comparing the input turbine speed (speed sensor NT) signal with the counter gear speed (speed sensor NC) signal, the Engine Control Module (ECM) detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to various conditions. As a result, the gears shift smoothly.
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).
