Solenoid Valve Check

Use the scan tool to measure the ATF temperature and set the ATF temperature to 20°C (68°F).
Remove the A/T control solenoid valve assembly connector.

Measure the resistance between the solenoid valve terminals.
Check that the measured values are within the standard values at Steps 1 and 2 .

If within the standard value, check the power supply and the ground circuits.
If not within the standard value, drain the ATF and remove the valve body cover.
Disconnect the connectors of each solenoid valve.

Measure the resistance between terminals 1 and 2 of each solenoid valve.
Standard value: 2.7 - 3.4 ohm [at 20°C (68°F)]

If the resistance is not within the standard value, replace the solenoid valve.
If within the standard value, check each wiring harness between A/T control solenoid valve assembly and each solenoid valve. If a problem is not found at the steps above, check the solenoid valve O-rings and replace if necessary.
