Toyota Venza: Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

Toyota Venza Service Manual / U660e Automatic Transmission / Transaxle / Automatic Transaxle System / Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

DESCRIPTION

Refer to DTC P2714 (See page ).

DTC No.	DTC Detection Condition	Trouble Area
P2716	Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1-trip detection logic).	Open or short in shift solenoid valve SLT circuit Shift solenoid valve SLT TCM

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.

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:

Tester Connection	Condition	Specified Condition
12 (SLT+) - 7 (SLT-)	20°C (68°F)	5.0 to 5.6 Ω
12 (SLT+) - Body ground	Always	10 kΩ or higher
7 (SLT-) - Body ground	Always	10 kΩ or higher
12 (SLT+) - All other terminals except 7 (SLT-)	Always	10 kΩ or higher
7 (SLT-) - All other terminals except 12 (SLT+)	Always	10 kΩ or higher

REPLACE TCM

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:

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

(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.
