MONITOR DESCRIPTION

This DTC indicates that a pulse is not output from the speed sensor NT (turbine (input) speed sensor) or is output

While the vehicle is operating in the 4th, 5th or 6th gear position with the shift lever in D, if the input shaft

revolution is less than 300 rpm*1 although the output shaft revolution is more than 1000 rpm or more*2, the

ECM detects the trouble, illuminates the MIL and stores the DTC.

HINT:

*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is approximately 50 km/h (30 mph) or more.
