MONITOR DESCRIPTION
This DTC indicates that a pulse is not output from the speed sensor NT (turbine (input) speed sensor) or is output
signal.
While the vehicle is operating in 4th, 5th or 6th gear with the shift lever in D, if the input shaft speed is less than
300 rpm*1 although the output shaft speed is 1000 rpm or more*2, the ECM detects the trouble, illuminates the
MIL and stores the DTC.
HINT:
*1: A pulse is not output or is irregularly output.
*2: The vehicle speed is approximately 50 km/h (30 mph) or more.
