Inspection of Electronic Control Components

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:

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 battery (-) terminal and terminal (4) to the battery (+) terminal.





3. Check the continuity between the terminal (1) and the 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 not within the standard value, replace the solenoid valve.
