Purpose/Function
The turbine/input shaft speed sensor detects the rotation speed of the input shaft (low clutch drum).
The output shaft speed sensor detects the rotation speed of the output shaft (primary gear).
The turbine/input shaft speed sensor and output shaft speed sensor signals are used for automatic shift control, manual shift control, and the on-board diagnostic system.
Construction
The turbine/input shaft speed sensor and output shaft speed sensor are both integrated with the TCM and built-into the control valve body.
Operation
The turbine/input shaft speed sensor changes the output signal according to the rotation speed of the low clutch drum.
The output shaft speed sensor changes the output signal according to the rotation speed of the primary gear.
Crankshaft Position (CKP) Sensor Inspection
Visual Inspection
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. Be sure there is no foreign material on the CKP sensor when
replacing.

Cruise Control System
Outline
Enables driving at a constant speed by setting the vehicle speed with the
cruise control switch instead of operating the accelerator pedal.
The PCM controls the throttle valve actuator to maintain the vehicle at a
constant speed.
