Inspection of Electronic Control Components

A/T CONTROL COMPONENT CHECK

1. CRANKSHAFT POSITION SENSOR CHECK

2. THROTTLE POSITION SENSOR CHECK

3. 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.

4. PARK/NEUTRAL POSITION SWITCH CHECK

5. STOPLIGHT SWITCH CHECK

6. VEHICLE SPEED SENSOR CHECK

7. DUAL PRESSURE SWITCH CHECK

8. 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.

9. 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.
