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

WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT TRANSMISSION WIRE (SLT)

Disconnect the transmission wire connector from the transaxle.

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

Standard Resistance

Tester Connection	Condition	Specified Condition
3 (SLT+) - 8 (SLT-)	20°C (68°F)	5.0 to 5.6 Ω

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

Standard Resistance (Check for short)

Tester Connection	Condition	Specified Condition
3 (SLT+) - Body ground	Always	10 kΩ or higher
8 (SLT-) - Body ground	Always	↑

NG → See step 3

OK: Go to next step

CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

Connect the transmission wire connector to the transaxle.

Disconnect the ECM connectors.

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

Standard Resistance

Tester Connection	Condition	Specified Condition
B29-61 (SLT+) - B29-60 (SLT-)	20°C (68°F)	5.0 to 5.6 Ω

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

Standard Resistance (Check for short)

Tester Connection	Condition	Specified Condition
B29-61 (SLT+) - Body ground	Always	10 kΩ or higher
B29-60 (SLT-) - Body ground	Always	↑

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR

OK → See step 5

INSPECT SHIFT SOLENOID VALVE SLT

Remove the shift solenoid valve SLT.

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

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.

NG → See step 6

OK → See step 4

REPAIR OR REPLACE TRANSMISSION WIRE. Refer to REMOVAL
REPLACE ECM (for 2ZR-FE). Refer to REMOVAL
REPLACE SHIFT SOLENOID VALVE SLT. Refer to DISASSEMBLY
