Steering Angle Sensor Inspection

WARNING: This page is about a different car, the 2013 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

Remove the column cover, (See COLUMN COVER REMOVAL/INSTALLATION ).
Connect the plus (+) end of a tester to steering angle sensor terminal A and the minus (-) end of the tester to terminal B (GND).
Switch the ignition ON (engine off or on).
Turn the steering wheel to the left and right.
Verify that the voltage from steering angle sensor terminal A to B (GND) is as indicated in the table.

- If the voltage can be verified as indicated in the table, go to the next step.
- If the voltage is not as indicated in the table, replace the clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM] ). (See CLOCK SPRING REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM] ).
Switch the ignition to off.
Connect the plus (+) end of a tester to steering angle sensor terminal C and the minus (-) end of the tester to terminal B (GND).
Switch the ignition ON (engine off or on).
Turn the steering wheel to the left and right.
