Steering Angle Sensor Inspection

NOTE:

If the steering angle sensor is removed from the clock spring, the steering angle sensor absolute angle could change, therefore, do not remove the steering angle sensor from the clock spring.
If the steering angle sensor is replaced, replace it together with the clock spring.

Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION .)
Connect a tester positive side to steering angle sensor terminal A, and connect terminal B (ground) to negative side.

- If the voltage is not as indicated in the table, replace the clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
Switch the ignition to off.
Connect a tester positive side to steering angle sensor terminal C, and connect terminal B (ground) to negative side.
Switch the ignition ON (engine off or on).
