The car failed because it has a problem
The problem will require repair
There are literally a thousand possible problems, each with a special repair needed.
Yes if it is emissions related.
Vehicles can fail emissions tests due to several key components. Common culprits include a malfunctioning catalytic converter, which reduces harmful emissions, and faulty oxygen sensors, which monitor air-fuel mixtures. Additionally, issues with the fuel injection system or exhaust leaks can contribute to increased emissions. Regular maintenance and timely repairs can help prevent these failures.
That will cause you to fail an emissions inspection. Anything which triggers the CEL will, because everything which triggers it will adversely impact the emissions system on that vehicle.
Depends on which of the readings failed. Was it CO (carbon monoxide), HC (hydrocarbons), NOx (nitrous of oxides), or a combination of them?
A dirty fuel filter could force a lean condition causing the check engine light to iluminate. In which case the vehicle would fail an emissions test.
you will fail the emissions test.
The computer has detected a problem with the emissions controls. Have the computer scanned for trouble codes. Get this fixed, as it can cause other parts to fail, as in, the catalytic converter, O2 sensor.
Usually it is the O2 sensor
Yes, it can if faulty or missing.
No, but you will fail an emissions test.
The vehicle will fail an emissions test.
The airbag light would have nothing to do with emissions. If they are doing a safety inspection, it would fail.
