DTC P2716 PRESSURE CONTROL SOLENOID "D"
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
Line Pressure valve SLT, under electronic control, to precisely and minutely
Control Pressure
modulate and generate the line pressure according the extent
of the accelerator pedal depressed or the output of engine pow-
er.
This controls the line pressure and provides smooth shifting.
Current Flow to Solenoid D02290 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.
ON (*): 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
OFF is the period of non-continuity, then
1 cycle
Duty Ratio=A/(A+B) x 100 (%)

MONITOR DESCRIPTION
When an open or short in the linear solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault.
The ECM will turn ON the MIL and store the DTC.

INSPECTION PROCEDURE
1 INSPECT TRANSMISSION WIRE(SLT)
(a) Disconnect the transmission wire connector from the
SLT+ transaxle.
(b) Measure the resistance between the terminals SLT+ and
SLT-.
