A/T Control Component Check

The TP Sensor 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 TP Sensor changes. The ECM detects the throttle valve opening based on voltage change.

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

1. Remove the vehicle speed sensor and connect a 3-10 KΩ resistance as shown in the illustration.
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 to and disconnected from the battery.
4. If there is a problem, replace the A/T control relay.
