New Smog Check OBD Reference Guide

The role of California consumers cannot be overlooked. By participating in the Smog Check Program and keeping their vehicles in proper maintenance, they have made an impact. California consumers have also embraced hybrid and electric vehicles at a higher rate than the rest of the country, signaling that Californians are serious about the environment and are willing to invest in cleaner alternatives. Last, but certainly not least, the automotive repair industry is on the front line in the war on smog. Each time a vehicle fails a mandated Smog Check, skilled technicians…
