KICK DOWN SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The kick±down switch is turned ON when the accelerator pedal is depressed to the full throttle and sends
signals to ECM.
When the kick±down switch is turned ON, the ECM controls gear shifting according to the programmed shift
diagrams.
If a short circuit develops in the kick±down switch, the ECM disregards the kick±down signals and controls
shifting at the normal shift points.

DTC P2716 PRESSURE CONTROL SOLENOID ºDº
ELECTRICAL (SHIFT SOLENOID SLT)
CIRCUIT DESCRIPTION
The throttle pressure that is applied to the primary regulator
valve (which modulates the line pressure) causes the solenoid
valve SLT, under electronic control, to precisely and minutely
modulate and generate the line pressure according to the ex-
tent of the accelerator pedal depressed or the output of engine
power.
This controls the line pressure and provides smooth shifting.
Upon receiving a signal of the throttle valve opening angle, the
ECM controls the line pressure by sending a predetermined (*)
duty ratio to the solenoid valve, modulating the line pressure
and generating throttle pressure.
(*): Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle.
For example, if A is the period of continuity in one cycle, and B
is the period of non±continuity, then
Duty Ratio=A/(A+B) x 100 (%)

DTC P0793 INTERMEDIATE SHAFT SPEED SENSOR
ºAº
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the counter gear. By comparing the counter gear speed signal (NC)
with the direct clutch speed sensor signal (NT), the ECM detects the shift timing of the gears and appropriate-
ly controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shift-
ing is performed.
