2004 Acura TL 3.2L P2229 Fault Code: Symptoms and Diagnosis

My 2004 Acura TL 3.2L is showing three orange dashboard warnings: Check Engine, VSA (Vehicle Stability Assist), and Traction Control (indicated by a triangle). Despite these lights, the vehicle drives perfectly smoothly with no performance issues. I have already replaced the barometric pressure sensor and confirmed that the catalytic converter is not clogged. There are no noticeable symptoms associated with this fault code—no backfiring, difficulty accelerating, or fuel odor. The car performs as if it were new. Additionally, my friend recently reported a similar issue on his 2006 Acura TL 3.2L model, which suggests a potential shared system concern.
