A/T FLUID TEMPERATURE SENSOR CONTINUITY CHECK





1. Remove the A/T fluid temperature sensor.
2. Measure the resistance between terminals 1 and 2 of the A/T fluid temperature sensor connector.





Standard value:

3. Replace the sensor if not within the standard value.

A/T CONTROL RELAY CHECK








1. Remove the A/T control relay.
2. Use jumper wires to connect the A/T control relay terminal 2 to the negative battery terminal and terminal 4 to the positive battery terminal.
3. Check the continuity between terminal 1 and terminal 3 of the A/T control relay when the jumper wires are connected to and disconnected from the battery.
4. If there is any problem with the A/T control relay, replace it.

SOLENOID VALVE CHECK





1. Remove the valve body cover.
2. Disconnect the connectors of each solenoid valve.





3. Measure the resistance between terminals 1 and 2 of each solenoid valve.





Standard value:

4. If the resistance is not within the standard value, replace the solenoid valve.
