Line Pressure Solenoid Valve A Test
- Connect the HDS to the DLC (A).
- 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 (see DLC CIRCUIT TROUBLESHOOTING ).
- Select Line Pressure Solenoid Valve in the Miscellaneous Test Menu with the HDS.
- 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.
- Remove the secondary valve body (see SECONDARY VALVE BODY REPLACEMENT ).
- Measure the resistance of line pressure solenoid valve A between connector terminals No. 1 and No. 2.
Standard: 13.3-16.9 Ω at 32-86°F (0-30°C)
- If the resistance is out of the standard, replace the secondary valve body (see SECONDARY VALVE BODY REPLACEMENT ).
- If the resistance is within the standard, go to step 7 and check the solenoid valve for a clicking sound.
- 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 (see SECONDARY VALVE BODY REPLACEMENT ).
- Install the secondary valve body (see SECONDARY VALVE BODY REPLACEMENT ).
