Auxiliary Emission Control Device (AECD) means any element of design which senses temperature, vehicle speed, engine RPM, transmission gear, manifold vacuum, or any other parameter for the purpose of activating, modulating, delaying, or deactivating the operation of any part of the emission control system.

How much does it cost to fix emission control system?
If your vehicle failed emission testing and it needs repairing, then the cost will depend on the exact cause, but the repair work typically starts around $200. Replacing your exhaust system depends on the type of car you drive, but that work starts at approximately $175.
What does it mean when the emission control system light comes on?
If your light is on, it typically means the car's emissions control system is faulty, and the vehicle is polluting the air beyond allowable federal standards. A vehicle in this condition would fail an emissions inspection or smog check.
What is an emission control system fault?
Emissions system fault
A component of this is the oxygen sensor, which can sense if the engine is burning too much or not enough fuel. This can trigger the CEL to indicate that the car is either running too rich or too lean, or that there's an issue with the sensor itself.
What is the purpose of the emission system?
Your vehicle's exhaust system is designed to take care of toxic emissions your car produces. It will 1) direct harmful hydrocarbons away from the driver and passengers, and 2) reduce the air polution your car releases into the environment, helping keep the air clean.
Is it safe to drive with emission control light on?
So, is it safe to drive with the Emissions Control Light on? Yes, as long as it is the only light that has come on, you do not have to worry about your safety.
Will an EVAP code clear itself?
If the condition that caused it to come on is a minor fault, and stops occurring, then yes, it will clear itself. If the condition indicates a larger problem, then it will stay on until cleared manually.
What are emissions problems?
Vehicle emissions are treated to ensure carbon monoxide and other dangerous gases are converted to safer gases before being released into the environment. If you smell gasoline inside the cabin of your car or outside of it, you've got an emissions problem.
What causes emission problems in a car?
Ignition defects including dirty spark plugs, leaking or open-circuited spark plugs or wires, or defective ignition coils can all result in a shortage of spark energy. Any shortage of spark energy may cause high HC emissions. If the spark occurs at the wrong time, incomplete combustion and high hydrocarbons may result.
What does a yellow check engine light mean?
Look for a serious problem that requires immediate attention. Check your dashboard gauges and lights for indications of low oil pressure or overheating. ... On some cars, a yellow check engine light means investigate the problem and a red one means stop right now. Try tightening your gas cap.
Is emission service necessary?
Emissions tests are a key part of car maintenance and are good all around because they keep you car running better, longer and more efficiently; and they ultimately keep our environment cleaner.
What are some devices used to control emissions?
The most commonly used devices for controlling particulate emissions include: • electrostatic precipitators (wet and dry types), • fabric filters (also called bag houses), • wet scrubbers, and • cyclones (or multiclones).
How is emission control achieved?
The initial progress in diesel emission control was achieved through engine technologies, including changes in the combustion chamber design, improved fuel systems, charge air cooling, and special attention to lube oil consumption. ... These methods include diesel particulate filters, urea-SCR catalysts, and NOx adsorbers.
How long will check engine light stay on after tightening gas cap?
As soon as it's safe, pull over and make sure your gas cap is tight. Once you're back on the road, your check engine light should go off within 10 or 20 miles.
How many miles do I have to drive to reset computer?
So why is the light still on? Here's something you probably don't know: after clearing the car's computer you will need to drive for about 50 to 100 miles. As you drive your car the computer will monitor all the sensors and register the results.
How long does it take for a car computer to reset itself?
The Light Stays On
You may think that there is still a problem with the car after the repair, but it's because the light needs time to reset. The car's internal computer only resets after a set period where it checks all of its sensors once more. The reset can happen automatically after around 10 to 20 cycles.
