How to Get a Smog Test


Smog test is quite common in western and American states. In California, two reasons are there, due to which, (DMV) department of Motor vehicles, requires this thing, the smog test. And that’s when you sale your car to someone and the ownership of car changes, or after each two years.

Such kind of program can also be launched, in which, the department of motor vehicle require “test only” type of smog inspection for the vehicles. One thing is that all of the test stations can perform the regular test or inspection for smog but the regular smog inspecting station can’t perform test only inspection. It’s not in the authority of test only stations to repair or modify the car. They don’t even keep toolbox for this on the site. They are just allowed to fail or pass the smog inspection, which will be based on vehicle’s emissions computerized test.

And on the other hand, a smog inspection station, which is regular, can perform smog test and can also provide the modifications and the adjustments, so that the vehicle would not find any sort of problem, in pass the inspection. Many of the auto repair facilities own a licensed smog technician. You can search directory, or ask any of your mate that where I can find the facility for smog testing.

What the entire smog technician would do is that he will put all the date required about the vehicle into the computer owned by state before starting the smog inspection test. This will also contain registration form in matching with the information, of the vehicle, VIN, mileage, plate of license, engine size, weight of the vehicle and also its model.

Then the smog test will start, basic work is of RPM meter in this test.

At the end, when the test would be finished, then the computer will output a report, to let us know that either our vehicle has cleared or not. Two things would be done, Visual inspection and computerized part. Visual inspection would be done by the technician to let us know that either all the emission parts are ok or not. And the computerized part would suggest that either it requires modification or to give them certificate of smog clearance.

There can be multitude of reasons for the failure of the vehicles test. There might be the reason that some of the readings, which were on the report, were apparent, such as failing part or missing (Value of ERG), vacuum hoses, tune up etc. and also catalytic converter replacement. Other things will require diagnoses from computer to determine the problem.

You are not required to have repair at same shop. Some may charge you lesser for re-test. There are also some of the cases, where your vehicle can be exempted from repair.
