Steering Angle Sensor: Testing and Inspection
Fig. 5 Angle sensor component test
1.
Disconnect AAS control unit electrical connector, then place ignition switch in On position.
2.
Connect suitable ohmmeter to terminals I and J. With steering wheel in neutral position, meter should indicate approximately 25k ohms. Gradually
turn steering wheel 180° clockwise, meter should increase from 25k ohms to 50k ohms. Turn steering wheel back to neutral position, then
gradually turn wheel 180° counterclockwise, meter should increase from 25k ohms to 200k ohms.
3.
Connect ohmmeter to terminals I and L. With steering wheel in neutral position, meter should indicate 50k ohms.
4.
If resistance is not as specified in steps 2 and 3, check for broken wire in harness, repair as required.
5.
Remove steering column cover, then disconnect angle sensor electrical connector
6.
Connect suitable ohmmeter to terminals AO and AL, Fig. 5. With steering wheel in neutral position, meter should indicate approximately 25k
ohms. Gradually turn steering wheel 180° clockwise, meter should increase from 25k ohms to 50k ohms. Turn steering wheel back to neutral
position, then gradually turn wheel 180° counterclockwise, meter should increase from 25k ohms to 200k ohms.
7.
Connect ohmmeter to terminals AR and AL, Fig. 5. With steering wheel in neutral position, meter should indicate 50k ohms.
8.
If resistance is not as specified in steps 6 and 7, place steering wheel in neutral position, then align angle sensor matching marks.
