A/T Control Component Check

The TPS is a variable resistor type that rotates with the throttle body shaft to sense the throttle valve angle. As the throttle shaft rotates, the output voltage of the TPS changes. The ECM detects the throttle valve opening based on voltage change. (Refer to applicable FUEL SYSTEM article ).

1. Remove the oil temperature sensor.
2. Measure the resistance between terminals 1 and 2 of the oil temperature sensor connector.

1. Remove the vehicle speed sensor and connect a 3~10 KΩ resistance as shown in Fig 2 .
2. Turn the shaft of the vehicle speed sensor and check that there is voltage between terminals 2-3 (1 turn = 4 pulses).

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 and disconnected from the battery.

4. If there is a problem, replace the A/T control relay.

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