Just Smog on Chula Vista's Third Avenue is a Bureau of Automotive Repair STAR Certified test-only smog inspection station operating under ARD license 232493 since 1999. Vehicles that fail the BAR-97 or OIS emissions test at the station are referred to full-service repair facilities such as Becka Automotive, which hold both test-and-repair credentials to diagnose and correct the underlying fault. The test-only designation means the station performs no mechanical work and has no financial incentive tied to repair outcomes — a separation the BAR STAR program mandates to reduce conflicts of interest in the smog check process. Pre-sale and change-of-ownership inspections for dealership inventory — including used-vehicle stock from lots such as Toyota Chula Vista — move through the station's drive-through lane on the same Third Avenue corridor that anchors Chula Vista's smog check district. The station's OBD-II testing protocol reads and analyzes live datastream parameters across all 11 OBD mode requests, capturing freeze-frame data, oxygen-sensor waveforms, and catalyst-monitor readiness flags to generate the BAR-certified Vehicle Inspection Report.
