MONITOR DESCRIPTION
This DTC indicates that a pulse is not output from the speed sensor NT (turbine (input) speed sensor) or is output
signal.
While the vehicle is operating in 4th, 5th or 6th gear with the shift lever in D, if the input shaft speed is less than
300 rpm*1 although the output shaft speed is 1000 rpm or more*2, the ECM detects the trouble, illuminates the
MIL and stores the DTC.
HINT:
*1: A pulse is not output or is irregularly output.
*2: The vehicle speed is approximately 50 km/h (30 mph) or more.

1. DATA LIST
HINT:
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely
on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.

NORMAL CONDITION
DIAGNOSTIC NOTE
SPD (NT)
Input shaft speed/
Min.: 0 rpm
Max.: 12750 rpm
Lock-up ON (after warming up engine):
Input turbine speed (NT) is equal to
engine speed
Lock-up OFF (idling with shift lever in N):
Input turbine speed (NT) is nearly equal
to engine speed
Data is displayed in
SPD (NT) is always 0 while driving:
Open or short in the sensor or circuit.
SPD (NT) is always more than 0 and less than 300 rpm while driving the vehicle at 50 km/h (30 mph) or
more:
1.
INSPECT SPEED SENSOR NT INSTALLATION
(a) Check the speed sensor NT installation.
OK:
The installation bolt is tightened properly and there is no
clearance between the sensor and transmission case.
