DTC Descriptor
DTC P2714
- Pressure Control Solenoid D Performance (Shift Solenoid Valve SLT)
DTC P2716:
- Pressure Control Solenoid D Electrical (Shift Solenoid Valve SLT)
Diagnostic Fault Information
Circuit/System Description
The powertrain control module (PCM) provides a B+ and a control circuit to the shift solenoid valve SLT. 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 PCM adjusts the duty cycle of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Correct line pressure assures smooth shifting with varying engine torque outputs.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
P2714
The PCM detects a malfunction on the SLT, ON side, according to the revolution difference of the turbine, intermediate, output shafts and also by the oil pressure.
P2716
The PCM detects a short to ground or an open/high resistance on the B+ or control circuit of the shift solenoid valve SLT circuits.
Action Taken When the DTC Sets
DTC P2714 and P2716 are type A DTCs.
Conditions for Clearing the DTC
DTC P2714 and P2716 are type A DTCs.
Diagnostic Aids
* The battery must be fully charged. Refer to Battery Inspection/Test (Battery Inspection/Test).
* All resistance tests are conducted with the component at 20°C (68°F).

Circuit/System Verification
Note: If any other DTCs are set, diagnosis them first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code (DTC) List - Vehicle).
1. Operate the vehicle from zero to 66 km/h (40 mph) and back to zero. The vehicle should operate normally without resetting DTC P2714.
2. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Ignition OFF, disconnect the transmission harness connector.
2. Test for 5-6 ohm between the transmission component connector terminal 2 and terminal 7.
• If not within the specified value, test the transmission internal wire harness for an open/high resistance. If the circuit tests normal, replace the control valve body.
3. Test for greater than 10K ohm between the transmission component connector terminal 2 and ground and also terminal 7 and ground.
• If less than the specified value, test the transmission internal wire harness for a short to ground. If the circuit tests normal, replace the control valve body.
4. Ignition OFF, connect the transmission harness connector.
5. Disconnect the PCM X2 harness connector.
6. Test for 5-6 ohm between the PCM X2 harness connector terminal 75 and terminal 76.
• If not within the specified value, test the shift solenoid valve, SLT, voltage circuit and the ground circuit for an open/high resistance.
7. Test for greater than 10K ohm between the PCM X2 harness connector terminal 76 and ground.
• If less than the specified value, test the voltage circuit for a short to ground.
8. Test for greater than 10K ohm between the PCM X2 harness connector terminal 75 and ground.
• If less than the specified value, test the control circuit for a short to ground.
9. If all circuits test normal, replace the PCM.
Component Testing
1. Ignition OFF, remove the shift solenoid valve SLT.
2. Test for 5-6 ohm between terminals 1 and 2 of the solenoid valve SLT.
• If not within the specified value, replace the solenoid valve SL3.
3. Connect a 10 A fused jumper wire to terminal 1 and a non-fused jumper wire to terminal 2 of the solenoid valve SLT.
4. Momentary connect both ends of the jumper wire to a 12 V battery. The solenoid should energize and make a click sound.
• If the solenoid does not energize and click, replace the solenoid.
5. If all circuits test normal, refer to Symptoms - Automatic Transmission (Symptoms - Automatic Transmission).
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the repair.
* Control Valve Body Replacement (MVA 4 Speed - Automatic Transmission)
* Powertrain Control Module Replacement (Service and Repair)
* Powertrain Control Module Programming and Setup (Testing and Inspection)
