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 (see DLC CIRCUIT TROUBLESHOOTING ).
  3. Select Line Pressure Solenoid Valve A in the Miscellaneous Test Menu on the HDS.
  4. Check that line pressure solenoid valve A operates 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 (see BATTERY REMOVAL AND INSTALLATION ).
  6. Remove the battery base (see ENGINE REMOVAL ).
  7. Remove the starter (see STARTER REMOVAL AND INSTALLATION ).
  8. Remove the secondary valve body (see SECONDARY VALVE BODY REPLACEMENT  ).
  9. Measure the resistance of line pressure solenoid valve A between connector terminals No. 1 and No. 2.

    Standard: 13.8 - 17.1 Ω 

    • If the resistance is out of the standard, replace the secondary valve body, then go to step  11.
    • If the resistance is within the standard, go to step 10 and check the solenoid valve for a clicking sound.

  10. 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 11.
    • If no clicking sound is heard, replace the secondary valve body, then go to step 11.
  11. Install the secondary valve body (see SECONDARY VALVE BODY REPLACEMENT  ).
  12. Install the starter (see STARTER REMOVAL AND INSTALLATION ).
  13. Install the battery base (see ENGINE INSTALLATION ).
  14. Do the battery installation procedure (see BATTERY REMOVAL AND INSTALLATION ).
