Monitor Description

WARNING: This page is about a different car, the 2017 Lexus RC 350, 2017 Lexus RC 300, 2016 Lexus RC 350, 2016 Lexus RC 300, and 2015 Lexus RC 350. However, it is still accessible from the selected car via links, so may be relevant.

This DTC indicates that pulse are not output from the transmission revolution sensor (NT) (Turbine (input) speed sensor) or output irregularly. The NT terminal of the ECM detects the revolution speed signal from transmission revolution sensor (NT) (input RPM). The ECM outputs a shift signal comparing the transmission revolution sensor (NT) with the transmission revolution sensor (SP2).

While the vehicle is being driven in 4th, 5th or 6th gear with the shift lever in D, if the input shaft revolution (speed) is less than 300 rpm*1 with the output shaft revolution (speed) 1000 rpm or more*2, the ECM interprets this as malfunction, illuminates the MIL and stores this DTC.

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

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