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


DESCRIPTION

The throttle pressure that is applied to the primary regulator valve (which modulates the line pressure) causes the solenoid valve SLT, under electronic control, to precisely modulate and generate the line pressure according to the extent that the accelerator pedal is depressed or the output of engine power.
This controls the line pressure and provides smooth shifting characteristics.
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.
HINT:
*: The duty ratio is the ratio of the current ON time (A) to the total of the current ON and OFF time (A + B).
Duty Ratio (%) = A / (A + B) x 100

DTC No.
DTC Detection Condition
Trouble Area
P2716
Condition (a) and (b) below is detected for 1 sec. or more (1 trip detection logic):
(a) SLT - terminal: 0 V
(b) SLT - terminal: 12 V
  1. Open or short in shift solenoid valve SLT circuit
  2. Shift solenoid valve SLT
  3. ECM

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 illuminate the MIL and store the DTC.

  1. Disconnect the B29 wire connector.

  1. Measure the resistance of the transmission wire.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    2 (SLT+) - 7 (SLT-)
    		20°C (68°F)
    		5.0 to 5.6 Ω
    2 (SLT+) - Body ground
    		20°C (68°F)
    		10 kΩ or higher
    7 (SLT-) - Body ground
    		20°C (68°F)
    		10 kΩ or higher


NG
Go to step 3
OK


2.CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

  1. Connect the B29 wire connector.

  1. Disconnect the B32 ECM connector.

  1. Measure the resistance of the wire harness side connector.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    B32-76 (SLT+) - B32-75 (SLT-)
    		20°C (68°F)
    		5.0 to 5.6 Ω
    B32-76 (SLT+) - Body ground
    		20°C (68°F)
    		10 kΩ or higher
    B32-75 (SLT-) - Body ground
    		20°C (68°F)
    		10 kΩ or higher

  1. Remove the shift solenoid valve SLT.

  1. Measure the resistance of the solenoid valve.

    Standard resistance:
    5.0 to 5.6 Ωat 20°C (68°F)

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

    OK:
    Valve moves and makes operating noise.
