What happens if you fail a smog test?
Once you fail a car emissions test and you decide to pursue repairs, the cost might come as a surprise. Many of the problems that can cause your smog check to fail are pricey to repair. A catalytic converter replacement is routinely between $1,000 and $2,000 for part and labor.
How long does it take for a smog check on a car?
During the smog check, your car’s On-Board Diagnostics (OBD) system will indicate any problems to the technician. Older vehicles are evaluated via an emissions tester placed in the tailpipe. The test takes 20 to 30 minutes to perform.
What to do if check engine light code p0171 is triggered?
If check engine light code P0171 is triggered again, check the rest of the vacuum lines for leaks and continue to the rest of the diagnostic process. Remove the mass airflow sensor and clean the sensor using mass air flow cleaner or contact cleaner.
Can you get a tune up before a smog test?
Get a tune-up (but not right before the smog check). A tune-up is a great way to find and address any problems that could lead to a smog test failure. However, your car’s battery is disconnected during a tune-up, which resets its computer (and the emissions monitoring system).

What does p0171 mean on a 4 cylinder engine?
Code P0171 applies to 4-cylinder engines (Bank 1) as they generally have only one bank. If you have a V6 or V8 engine you can also get a P0174 code which refers to Bank 2. When the code says that the fuel system is “too lean,” it means that the computer has been adding more and more fuel, which is called Long Term Fuel Trim.
How often do you need a smog check in California?
In California, most counties require mandatory smog checks every two years. If you drive a vehicle that’s six years old or less, you’ve gotten lucky. You won’t need your car emissions test until it reaches six years of age.

How long does it take for a smog check?
The tester has to plug in a diagnostic computer and check for codes related to emissions failures. They need to use a sniffer tester to check vehicles for safe levels of hydrocarbons, nitrous oxides, and other pollutants. All in all, you can expect your smog check to take around 20 to 30 minutes.

What happens if you fail your car emissions test?
Typical components in your car emissions system are: If there’s a problem with any of these parts, your car emission test is all but guaranteed to fail. To accurately complete your vehicle testing for emissions-related issues, the testing facility has a few things to do. They have to: Bring your car up to normal operating temperature.
Why is my smog check OBD 2 incomplete?
There are several reasons why the monitors may be incomplete. If your car has recently been repaired for a problem that set a DTC (check engine on) and the technician cleared the DTC, he also erased the monitors. Also, if battery has been disconnected, replaced or needed a jump-start, the monitors may be erased.
What are the three parts of the smog inspection?
The overall smog inspection consists of three parts…the emissions test, which measures the smog coming out of the tailpipe; the visual inspection, to look for broken or modified parts; and the functional tests, where other systems are checked to see if they are working properly. The OBD II test is a functional test.
When does Smog Check Come Out the tailpipe?
It does not test what is going on when the engine is cold, idling, decelerating, etc. Also, not all the smog a car makes comes out the tailpipe.

When did California first start testing for smog?
California first started testing for smog back in the 1980’s when it became apparent that the emissions from vehicles were causing negative effects. In the 90’s, the smog check changed to adapt with the new technology and implemented a lot of programs around smog emissions and retiring vehicles.
