DESCRIPTION
The linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the duty cycle of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.
(*): 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(%)

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 transaxle.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for short)

2 CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

(a) Connect the transmission wire connector to the transaxle.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for short)


REPLACE ECM
3 INSPECT SHIFT SOLENOID VALVE SLT

(a) Remove the shift solenoid valve (SLT).
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.
OK: The solenoid makes an operating sound.
