Can you get a second opinion on a check engine light?
Getting a second opinion from a mechanic, on the other hand, is another matter. “If a check engine light is on, there’s something wrong,” said Tony Molla, vice president at the Automotive Service Association, in an email. “Precisely what that is depends on the skill and knowledge of the technician.
How is an emissions test done on a car?
Every engine gives off emissions, and in most areas, vehicles are only allowed to produce a certain amount. Years ago, the test used to require facilities to put your car on a dynamometer — essentially a vehicle treadmill — and hook up testing equipment to your tailpipes.
Do you have to have OBD-II emissions test?
Check with your state and county, as older cars in many states are exempt from tests. The OBD-II requirement in 1996 was “pretty much a line in the sand,” Tisdale said. “Anything prior to 1996 is going to need to have the treadmill test.”
How does fluorescence emission relate to excitation energy?
In addition, fluorescence emission is usually accompanied by transitions to higher vibrational energy levels of the ground state, resulting in further loss of excitation energy to thermal equilibration of the excess vibrational energy.

What happens when the emissions light comes on?
Merely A Sensor Error. When the emission light comes “ON,” but there are no interruptions in how your car operates, there is an issue with the sensor. This, in turn, means that there are no potential risks that you have to look after. It is a common system failure that leads to the dashboard light malfunctioning.
Is it safe to drive with emissions light on?
Can you drive with the exhaust emissions light on? It is safe to drive with an amber check engine light glowing on your dashboard, especially if you cannot detect any problems with the smooth operation of the car.
Why does a car have to pass emissions test?
“Every vehicle that’s manufactured has a federal [emissions] standard that it has to meet, and that onboard computer is designed to warn the driver of any system or any failure that would alter that,” explained Pete Meier, the technical editor at Motor Age, an industry publication for mechanics.
