Angle Sensor

Most of the time, you don't need to center the Steering Angle Sensor, but you should do it after replacing the steering gear, steering column, Steering Angle Sensor, intermediate shaft, abs controller, or if the car has been in a collision or otherwise physically damaged. The automated center procedure requires a scan tool, so you should first straighten the front wheels with the Steering Wheel and put the transmission in park. You should now put the scan tool onto the data link connector (DLC) and set the ignition to on without cranking the engine. On the scan tool, select the chassis/ebcm control system, vses, special function, and steering pos. Sensor calibration stages. Complete the auto-centering by following the instructions on the scan tool: first, turn the Steering Wheel left 5 degrees, then right 5 degrees, then center it. Make sure to clear out any set dtcs and conduct the diagnostic system check so you know there are no pending dtcs. The process to center the Steering Angle Sensor is completed.

The Steering Angle Sensor needs infrequent centering but requires it after particular service procedures which include steering gear replacement, steering column replacement, Steering Angle Sensor replacement, intermediate shaft replacement, abs controller replacement or collision-related physical damage. Start by aligning front wheels forward through steering wheel operation then set the transmission to park position. To begin the procedure you need to install the diagnostic tool (Tool Required: scan tool). Connect a scan tool to the data link connector (DLC) then activate the Ignition Switch on while maintaining an engine off state. Direct the scan tool to select chassis/ebcm control system vehicle stability enhancement system (VSES) and special function test followed by steering pos. Sensor calibration. The scan tool provides instructions to perform automated centering where users must turn the wheel first left 5 degrees then right 5 degrees and finally straight ahead. Disable any detected dtcs through clearing procedures before continuing with a diagnostic system check to ensure all dtcs remain cleared. All Steering Angle Sensor centering is finished.
