Monitor Description

WARNING: This page is about a different car, the 2006 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

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

While the vehicle is operating in the 4th, 5th or 6th gear position in the shift position of D, if the input shaft revolution is less than 300 rpm*1 although the output shaft revolution is 300 rpm or more*2 , the ECM detects the trouble, illuminates the MIL and stores the DTC.

*1: Pulse is not output or is irregularly output.

*2: The vehicle speed is approx. 50 km/h (31 mph) or more.
