A/T Control Component Check

A/T CONTROL COMPONENT CHECK

OIL TEMPERATURE SENSOR CHECK
1. Remove the oil temperature sensor.
2. Measure the resistance between terminals No.1 and No.2 of the oil temperature sensor connector.








STANDARD VALUE

VEHICLE SPEED SENSOR CHECK
1. Remove the vehicle speed sensor and connect a 3-10 K Ohms resistance as shown in the illustration.





2. Turn the shaft of the vehicle speed sensor and check that there is voltage between terminals 1-2 (1 turn = 4 pulses).

A/T CONTROL RELAY CHECK
1. Remove the A/T control relay.
2. Use jumper wires to connect A/T control relay terminal 2 to the battery (+) terminal and terminal 4 to the 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 a problem, replace the A/T control relay.

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 outside the standard value, replace the solenoid valve.

NOTE: Resistance of the solenoid valve connector.
