DTC P2714 Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT) |
DESCRIPTION
The linear 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 duty ratio* of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.- HINT:
- *: The duty ratio is the ratio of the current ON time (A) to the total of the current ON and OFF time (A + B).
- Duty Ratio (%) = A / (A + B) x 100

DTC No.
| DTC Detection Condition
| Trouble Area
|
P2714
| ECM detects malfunction on SLT (ON side) according to difference in revolutions of turbine (input), intermediate and output shaft (2 trip detection logic)
| - Shift solenoid valve SLT remains closed
- Valve body is blocked
- Torque converter clutch
- Automatic transaxle (clutch, brake, gear, etc.)
- ECM
|
MONITOR DESCRIPTION
In any forward position, when the difference between the revolutions of the turbine, intermediate and output shaft exceeds the specified value (varies with intermediate, output speed) determined by the ECM, the ECM illuminates the MIL and outputs the DTC. When shift solenoid valve SLT remains on, the oil pressure goes down and the clutch engagement force decreases.- NOTICE:
- If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be drivable.

INSPECTION PROCEDURE
- HINT:
- Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
- Warm up the engine.
- Turn the ignition switch OFF.
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch ON and turn the tester ON.
- Enter the following menus: Powertrain / Engine and ECT / Active Test.
- Perform the Active Test.
Tester Display
| Test Part
| Control Range
| Diagnostic Note
|
Activate the Solenoid (SLT)*
| [Test Details] Operate shift solenoid SLT and raise line pressure [Vehicle Condition]
- Vehicle stopped
- IDL: ON
- HINT:
- OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands SLT solenoid to turn OFF)
- ON: No action (normal operation)
| ON/OFF

- HINT:
- *: "Activate the Solenoid (SLT)" in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transaxle, which is used in the HYDRAULIC TEST (RAV4_ACA30 RM000000W7B0BGX.html) as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
1.CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2714) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: Powertrain / Engine and ECT / DTC / Current or Pending.
Read the DTCs using the tester.

- HINT:
- If any other codes besides P2714 are output, perform troubleshooting for those DTCs first.
2.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 battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.
- OK:
- Valve moves and makes operating sound.
3.INSPECT TRANSMISSION VALVE BODY ASSEMBLY |
Check the transmission valve body assembly.
- OK:
- There are no foreign objects on each valve.
4.INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY |
Check the torque converter clutch assembly (RAV4_ACA30 RM000001GS000WX.html).
- OK:
- The torque converter clutch operates normally.
