North Park Smog Test Only at 3827 Bancroft St holds a California Bureau of Automotive Repair STAR certification as a dedicated Test-Only station established in 2009. Vehicles that fail a smog inspection here and need mechanical emissions repair can be taken directly to T P Auto Repair on El Cajon Blvd for catalytic converter and O2 sensor service. The station handles California biennial registration smog checks, change-of-ownership transfers, and out-of-state vehicle certifications using BAR-97 and OIS dynamometer testing equipment. Gross-polluter vehicles requiring EVAP or EGR system repair before a retest can also schedule service at Sam Lee Auto Repair on El Cajon Blvd. The station's most demanding inspections involve directed gross-polluter vehicles whose OBD-II readiness monitors must cycle through a full drive pattern before the BAR system will accept a passing certificate.
