All You Should Know About East Haven Emissions Testing

East Haven emissions testing is the process of determining the level of air pollutants that are being emitted by a vehicle. It is virtually impossible for a vehicle not to emit pollutants but there is an acceptable level for each type of vehicle. If a vehicle fails the test, it has to go for repairs and thereafter, it will be subjected to another test by any authorized East Haven emissions testing team.

Smart car buyers sometimes hire East Haven emissions testing specialist to test a particular used vehicle before buying it.

Factors that make vehicles require emissions test

You can decide to test a vehicle before you buy it. This is necessary when you are planning to buy a used vehicle since brand new vehicles do not usually fail the test. Old vehicles tend to fail emissions test more than new ones, so the age of your vehicle can make it require the test.

If a vehicle is not registered in Connecticut, it may be necessary to test it before using it in the State. Since only gasoline-powered vehicle emit pollutants, non-gasoline powered vehicles like electric cars are usually exempted from it. This simply means that the type of fuel your vehicle uses is also a factor. In addition, in some states, it is mandatory for taxis to take the test annually.

The technical details of the test

While there may be slight differences from State to State, the test generally checks for the presence of carbon dioxide, carbon monoxide, nitrogen oxide, and hydrocarbons in the emission of vehicles and their quantities. If the amount of any of the listed pollutants rises above the accepted level, it means the vehicle being tested has failed the test.

Cost of the test

The cost of the test depends on the location as it varies from state to state. In addition, it also depends on type and size of the vehicle being tested. Mandatory annual tests are relatively lower in cost. Some service providers offer free retest if the vehicle is repaired in their shop after a failed test.

Common causes of emission test failure

While there may be many reasons for this, the commonest one is a faulty injection. Faulty injections lead to rich fuel mixture which in turn gives off high levels of carbon dioxide and other dangerous gases. There are several other mechanical problems that can also cause this problem.

The air injection system introduces fresh into the exhaust of vehicles and if this system becomes faulty, the amount of fresh air in the exhaust will be minimal thereby leading to a high amount of poisonous gases in its emission. Other common causes are vehicle vacuum leaks, defects in the ignition system of a vehicle, and faulty oxygen sensor.

Cost of repair

It is impossible to put a figure as the repair cost for a car that failed emission test. The cost depends on the cause of the failure.

Prevention is always better and cheaper than cure so you should focus on preventing the situation whereby your vehicle will fail the test. The best way to prevent this is by going for routine maintenance checks and oil change regularly as recommended by the manufacturer of your vehicle.
