INSPECT SHIFT SOLENOID VALVE SLT

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


DESCRIPTION

The shift 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 shift solenoid valve SLT 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 shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.

  1. Remove the shift solenoid valve SLT.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance :
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C (68°F)
    		5.0 to 5.6 Ω

  1. 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.
