Emission cut scores for all counties are the same. The difference between
your Toyota being registered in specific counties, is that particular
counties smog check administration requirements, meaning, the county will
determine when, how often, and the type of smog check your Toyota pickup
truck will be administered, a basic smog check or an enhanced smog test.
The main difference between the Basic and Enhanced Test is that the Basic
Test does not require the vehicle to be driven on a dynamometer while an
emissions sample is collected from the tailpipe. Instead the vehicle's
exhaust is collected and tested while the engine is at idle and 2500rpm. A
smog station which is authorized to perform the Enhanced Test, can conduct a Basic Smog test as well.
