Code P0791 2014 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 vehicle is operating in 2nd, 3rd, 4th, or 5th 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). P0791 code is detected when the input speed sensor voltage is more than 1.9V or less than 0.1V for 2 seconds or more.
What are the Possible Causes of the DTC P0791 2014 Toyota RAV4?
- Faulty Speed sensor NC (Transmission Revolution Sensor)
- Speed sensor NC harness is open or shorted
- Speed sensor NC circuit poor electrical connection
- Faulty Engine Control Module (ECM)
