Size Does Matter

According to Honda, mismatched tire sizes will intermittently set VSA DTC 84-12 -- steering angle sensor (SAS) neutral position memorization incomplete.

The VSA system does a center point check of the steering at the start of every drive cycle by comparing the SAS to wheel speeds. If all of the wheel speeds don’t match at some point, the check won’t complete and the DTC will set.

Make sure that all tires match the size that’s listed on the driver’s door jamb label, have matching tread depth and are properly inflated. If the tires are mismatched or have significantly different tread depths, correct before continuing.
