The smog technician is correct; San Diego is an "enhanced" smog check area,
and smog tests there require a slightly different smog inspection process
(one that uses the dynamometer during the smog check) that San Luis Obispo
smog stations do not have. Unfortunately you will need to drive your Toyota
Camry to an enhanced county. You don't need to go back to San Diego, but you
do need to drive at least to the nearest county which is an enhanced smog
check area close to San Luis Obispo; in this case being first Ventura county
and then Los Angeles county.
