DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) |
DESCRIPTION
Refer to P2714 (YARIS_NCP93 RM000000W830FNX_01.html).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 detecting logic).
| - Wire harness or connector
- Transmission wire
- Shift solenoid valve SLT
- ECM
|
MONITOR DESCRIPTION
When an open or short in the linear solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault. The ECM turns on the MIL and stores the DTC.

INSPECTION PROCEDURE
- NOTICE:
- Perform the universal trip to clear permanent DTCs (YARIS_NCP93 RM000000W770OEX.html).
| 1.INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE 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
|
3 (SLT+) - Body ground
| Always
| 10 kΩ or higher
|
8 (SLT-) - Body ground
| Always
| 10 kΩ or higher
|

| 2.CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
Connect the transmission wire connector to the transaxle.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
C51-73 (SLT+) - C51-72 (SLT-)
| 20°C (68°F)
| 5.0 to 5.6 Ω
|
C51-73 (SLT+) - Body ground
| Always
| 10 kΩ or higher
|
C51-72 (SLT-) - Body ground
| Always
| 10 kΩ or higher
|

|
|
| 3.INSPECT SHIFT SOLENOID VALVE SLT |
Remove 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 operating sounds.
