INSPECT SHIFT SOLENOID VALVE SLT
DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)
DESCRIPTION
The shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the current of the SLT solenoid valve 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 | An open or short is detected in the shift solenoid valve SLT circuit for 1 sec. 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 turn on the MIL and store the DTC.

INSPECTION PROCEDURE
| 1.INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT) |
Disconnect the transmission wire connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| 14 (SLT+) - 6 (SLT-) | 20°C (68°F) | 5.0 to 5.6 Ω |
| 14 (SLT+) - Body ground | Always | 10 kΩ or higher |
| 6 (SLT-) - Body ground | Always | 10 kΩ or higher |

(Transmission Wire) |
| 2.CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| C45-9 (SLT+) - C45-8 (SLT-) | 20°C (68°F) | 5.0 to 5.6 Ω |
| C45-9 (SLT+) - Body ground | Always | 10 kΩ or higher |
| C45-8 (SLT-) - Body ground | Always | 10 kΩ or higher |

| 3.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 |
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 |
