U660F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P2716: Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

DTC P2716 - Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

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 TCM adjusts the duty ratio* 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 electrical current on time (A) to the total of the electrical current on and off time (A + B).
Duty Ratio (%) = (A / (A + B)) x 100









MONITOR DESCRIPTION

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

INSPECTION PROCEDURE
NOTICE: Perform the universal trip to clear permanent DTCs DTC Check / Clear.

PROCEDURE

1. INSPECT TRANSMISSION WIRE (SLT)




(a) Remove the TCM from the transaxle.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





Result:





B -- REPLACE TCM
A -- Continue to next step.

2. INSPECT SHIFT SOLENOID VALVE SLT




(a) Remove shift solenoid valve SLT.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





Text in Illustration





(c) Connect a battery positive (+) lead with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.
OK:
Valve moves and makes an operating sound.

NG -- REPLACE SHIFT SOLENOID VALVE SLT
OK -- REPLACE TRANSMISSION WIRE
