Encinitas STAR Smog & Auto Repair on Encinitas Boulevard holds California Bureau of Automotive Repair STAR certification under Station #300634 as a licensed Test and Repair facility. That combined license lets the same technician diagnose an OBD-II fault, replace a failed catalytic converter or oxygen sensor, and re-certify the vehicle in one bay cycle — eliminating the multi-shop routing that post-collision clients of Caliber Collision sometimes face for structural-to-emissions clearance. Full-service capabilities span engine diagnostics, brake overhaul, transmission rebuilds, AC recharge, and auto electrical troubleshooting for both domestic and foreign vehicles. Bilingual service in English and Spanish supports the diverse commuter corridor along Encinitas Boulevard east of the I-5 interchange. OBD-II scan data drives every diagnosis, with replacement catalytic converters, EGR valves, and oxygen sensor assemblies sourced through NAPA Auto Parts for factory-spec emissions compliance. Highest-complexity services include evaporative emission control system leak detection via smoke-machine testing and PCM reflash procedures for post-repair readiness monitor verification.
