Toyota Tundra (2015 year). Manual — part 692
MONITOR DESCRIPTION
This DTC indicates that a pulse is not output from the speed sensor NT (turbine (input) speed sensor) or is output
While the vehicle is operating in the 4th, 5th or 6th gear position with the shift lever in D, if the input shaft
revolution is less than 300 rpm*1 although the output shaft revolution is more than 1000 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 (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.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
(g) According to the display on the Techstream, read the Data List.

NORMAL CONDITION
DIAGNOSTIC NOTE
SPD (NT)
Input shaft speed/
Min.: 0 rpm
Max.: 12750 rpm
Lock-up is:
ON (after warming up engine): Input
turbine speed (NT) is equal to engine
speed
OFF (idling with shift lever on 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:
Sensor trouble, improper installation, or intermittent connection trouble in the circuit.
PROCEDURE
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.
