INSPECT SHIFT SOLENOID VALVE SLT
DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) |
DESCRIPTION
Shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and vehicle speed sensor. The ECM adjusts the current of shift solenoid valve SLT to control the hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.DTC Code
| DTC Detection Condition
| Trouble Area
|
P2716
| Open or short is detected in the 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
- 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.

| 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
|
Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.
- OK:
Measurement Condition
| Specified Condition
|
- Battery positive (+) with a 21 W bulb → Terminal 2
- Battery negative (-) → Terminal 1
| Valve moves and makes an operating noise
