- Shift Solenoid Valve E Stuck ON
- Shift Valve E Stuck
- A/T Clutch Pressure Control Solenoid Valve A Stuck OFF
- Warm up the engine to normal operating temperature (the radiator fan comes on).
- Make sure that the transmission is filled to the proper level, and check for fluid leaks.
- Drain the ATF (see step 3
through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer have metal debris or excessive clutch material?
YES -Replace the transmission, then go to step 14.
NO -Replace the ATF (see ATF REPLACEMENT ), then go to step 4.
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears.
- Monitor the OBD STATUS for P1731 in the DTCs MENU with the HDS.
Does the HDS indicate FAILED?
YES -Go to step 8.
NO -If the HDS indicates PASSED, intermittent failure, the system is OK at this time. If the HDS indicates NOT COMPLETED, go to step 6.

- Select Shift Solenoid Valve E in the Miscellaneous Test Menu, and check that shift solenoid valve E operates with the HDS.
Is a clicking sound heard?
YES -Go to step 10.
NO -Replace shift solenoid valve E (see SHIFT SOLENOID VALVE TEST, REPLACEMENT, AND SHIFT SOLENOID WIRE HARNESS REPLACEMENT ), then go to step 12.
- Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS.
Does the HDS indicate NORMAL?
YES -Intermittent failure, the system is OK at this time.
NO -Follow the instructions indicated on the HDS according to the test result, if the HDS has not determined the cause of the failure, go to step 11. If a part is replaced, go to step 12.
- Inspect A/T clutch pressure control solenoid valve A (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A TEST
).
Does A/T clutch pressure control solenoid valve A work properly?
YES -Repair the hydraulic system related to shift valve E, or replace the transmission, then go to step 14.
NO -Replace A/T clutch pressure control solenoid valve A (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A REPLACEMENT ), then go to step 12.
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears.
- Check for Pending or Confirmed DTCs with the HDS.
