Line Pressure Solenoid Valve A Test

Line Pressure Solenoid Valve A Test

1. Connect the HDS to the DLC (A).





2. Turn the ignition switch to ON (II). 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 in the Miscellaneous Test Menu with 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 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. Remove the secondary valve body Secondary Valve Body Replacement.

6. 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 Secondary Valve Body Replacement.
- If the resistance is within the standard, go to step 7 and check the solenoid valve for a clicking sound.





7. 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 8.
- If no clicking sound is heard, replace the secondary valve body Secondary Valve Body Replacement.

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