INSPECTION PROCEDURE
1 INSPECT TRANSMISSION WIRE(SLT)
(a) Disconnect the transmission wire connector from the
transaxle.
(b) Measure the resistance between terminals SLT+ and
SLT± of the transmission wire connector.
OK:
Resistance: 5.0 to 5.6 at 20
C (68
F)
(c) Measure the resistance between body ground and that
SLT+ as well as SLT± of the transmission wire connector.
OK:
Resistance: 1M or higher

DTC P0793/67 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.

DTC P0743 TORQUE CONVERTER CLUTCH CIRCUIT
ELECTRICAL (SHIFT SOLENOID VALVE
DSL)
CIRCUIT DESCRIPTION
The shift solenoid valve DSL is turned ON and OFF by signals from the ECM in order to control the hydraulic
pressure operation the lock±up relay valve, which then the controls operation of the lock±up clutch.
DTC No.DTC Detection ConditionTrouble Area
P0743
Either (a) or (b) is detected at 1 time:
(2 trip detection logic)
(a) Solenoid resistance is 8  or less short circuit when sole-
noid is energized
(b) Solenoid resistance is 100 k or more open circuit when
solenoid is not energized

DTCP0724BRAKE SWITCH ºBº CIRCUIT HIGH
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling while dr\
iving in lock±up condition, when
brakes are suddenly applied.
When the brake pedal is depressed, this switch sends signals to the ECM. Then\
the ECM cancels the opera-
tion of the lock±up clutch while braking is in progress.

driven (2±trip detection logic).

CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT)
