Monitor Description

This DTC indicates that a pulse is not output from the speed sensor NT (input speed sensor) or is output only a little. The NT terminal of the ECM detects the revolving signal from the speed sensor (NT) (input RPM). The ECM outputs a gear shift signal comparing the input speed sensor (NT) with the output speed sensor (SP2).

While the vehicle is operating in the 4th or 5th gear position with the shift lever on D, if the input shaft revolution is less than 300 rpm *1 although the output shaft revolution is 1,000 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 (31 mph) or more.
