DESCRIPTION
The solenoid (SLT) valve 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 to the solenoid (SLT) valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
|---|---|---|---|---|---|
| P2716 | Pressure Control Solenoid "D" Electrical | While the engine is running, an open or short is detected in the solenoid (SLT) valve circuit for 1 second (1-trip detection logic). |
|
Comes on | DTC stored |
MONITOR DESCRIPTION
When an open or short in the solenoid (SLT) valve circuit is detected, the ECM interprets this as a malfunction, illuminates the MIL and stores this DTC.
CONFIRMATION DRIVING PATTERN
Tech Tips
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 2 minutes or more.
Turn the ignition switch to ON and turn the GTS on.
Start the engine.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P2716.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |
|
Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.
