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 in the table below and proceed to the page given.
Hint:
*1: "Comes on" means the malfunction indicator lamp
(mil) illuminates.
*2: "Dtc stored" means the ecm memorizes the
malfunction code if the ecm ...
System voltage
Description
The battery supplies electricity to the ecm even when the ignition switch is
in the off position. This
power allows the ecm to store data such as dtc history, freeze frame data and
fuel trim values. If the
battery voltage falls below a minimum level, the memory is cleared and ...
Front passenger side - side airbag sensor circuit malfunction
Description
The side airbag sensor rh consists of parts including the diagnostic circuit
and the lateral deceleration
sensor.
When the center airbag sensor receives signals from the lateral deceleration
sensor, it determines
whether or not the srs should be activated.
