Description
This sensor detects the rotation speed of the turbine, which shows the input revolution of the transaxle. By comparing the input speed signal (nt) with the counter gear speed sensor signal (nc), the ecm detects the shift timing of the gears and controls the engine torque and hydraulic pressure according to various conditions. As a result, smooth gear shifting is achieved.
Monitor description
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 and 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.

Inspection procedure
Hint:
Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.
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.
Hint:
Ok: installation bolt is tightened properly and there is no clearance between the sensor and transaxle case.

Diagnostic trouble code chart
If a dtc is displayed during the dtc check, check the circuit
listed for the dtc in the table below (refer to the appropriate
page).
Hint:
When the srs warning light remains on and the normal
system code is output, a decrease in the source voltage is
likely to occur. This malfunction is n ...
Throttle actuator control system
Description
The throttle actuator is operated by the ecm, and opens and closes the
throttle valve using gears. The
opening angle of the throttle valve is detected by the throttle position (tp)
sensor, which is mounted on
the throttle body. The tp sensor provides feedback to the ecm in ord ...
Dtc check / clear
Check dtc
Connect the intelligent tester (with can vim) to the
dlc3.
Turn the ignition switch on and turn the intelligent
tester on.
Select the following menu items: diagnosis /
obd/mobd / immobiliser / dtc info /
current codes.
Check dtcs and then write them down.
