Monitor Description
WARNING: This page is about a different car, the 2006 Scion tC. However, it is still accessible from the selected car via links, so may be relevant.
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 (NC).
While the vehicle is operating in the 2nd, 3rd or O/D 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.
