Line Pressure Solenoid Valve A Test

Line Pressure Solenoid Valve A Test

1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.





2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting Testing and Inspection.

3. Select Line Pressure Solenoid Valve A in the Miscellaneous Test Menu on the HDS.

4. Check that line pressure solenoid valve A operate with the HDS. A clicking sound should be heard.

- If a clicking sound is heard, the solenoid valve is OK.
The test is complete, disconnect the HDS.
- If no clicking sound is heard, go to step 5 and test the solenoid valve.

5. Do the battery removal procedure Removal and Replacement.

6. Remove the air cleaner Service and Repair.

7. Remove the intake air duct.

8. Remove the battery heat shield.

9. Remove the auxiliary under-hood fuse/relay box.

10. Remove the battery base.

11. Remove the ATF dipstick and the starter.

12. Remove the secondary valve body Secondary Valve Body Replacement.

13. Measure the resistance of line pressure solenoid valve A between connector terminals No. 1 and No. 2.





- If the resistance is out of the standard, replace the secondary valve body, then go to step 15.
- If the resistance is within the standard, go to step 14 and check the solenoid valve for a clicking sound.





14. Connect a jumper wire from the negative battery terminal to line pressure solenoid valve A connector terminal No. 1, and connect another jumper wire from the positive battery terminal to connector terminal No. 2.

- If a clicking sound is heard, repair the wire between the PCM connector terminal and line pressure solenoid valve A, then go to step 15.
- If no clicking sound is heard, replace the secondary valve body, then go to step 15.

15. Install the secondary valve body Secondary Valve Body Replacement.
