In regards to the 3 lights issues, I had the exact same issue. No problem starting car, etc. but the battery was the issue causing weird dash warnings.

Easy fix to replace battery, and since you may have an older battery, the preventative maintenance is something you may want to do anyways.

The issue is with low voltage for the sensors overall, not with the actual components. Thus false readings. At least this was my experience. YMMV
