Steering Column Position Sensor: Testing and Inspection

TILT SENSOR INSPECTION
Continuity Inspection
1. Disconnect the connectors between the tilt sensor and the CPU.








2. Inspect continuity between following terminals of the tilt sensor side connector. If not as specified, replace the steering shaft component.


Resistance Inspection

Caution:
^ When using the ohmmeter, always make sure that no voltage is applied.
- If voltage Is applied, the ohmmeter may be damaged.

1. Disconnect the connectors between the tilt sensor and the CPU.





2. Measure the resistance between terminal B and terminal A of the tilt sensor side connector.
^ If not as specified, replace the steering shaft component.
Resistance Approximately 1 k Ohms

Voltage Inspection
At top dead point position
1. Insert the ignition key into the key cylinder (LOCK position).
2. Turn on the auto switch.
3. Remove the ignition key from the key cylinder to raise the steering wheel to the top dead point position.





4. Leave the connectors connected. Connect the terminal of the voltmeter to the tilt sensor side connectors variable resistance pole side terminal C (at the back of the connector), and connect the voltmeter's (-) terminal to the body ground side of the connector.
^ If not as specified, replace the steering shaft component.
Voltage Approximately 4.6 Volts

At bottom dead point position
1. Insert the ignition key into ignition key cylinder (ignition is at ON position).
2. Move the manual switch downward to lower the steering wheel to the bottom dead point position.





3. Leave the connectors connected. Connect the terminal of the voltmeter to the tilt sensor side connector's variable resistance pole side terminal C (at the back of the connector), and connect the voltmeter's (-) terminal to the body ground side of the connector.
^ If not as specified, replace the steering shaft component.
Voltage Approximately 1.4 Volts
