Things to Look Out for Before Your Next Vehicle Emissions Test
The first thing you have to do is clear the Check Engine light. This light is almost exclusively related to your car’s emissions, and it’s an immediate red light if it’s on during the test. A failing oxygen sensor is the most common culprit when it comes to the light staying on all the time. Replace the sensor, and you’ll likely see a change. Also, ask your mechanic if there should be any other reasons why the light might stay on even after the replacement.
Another way you can make sure the vehicle will operate at peak efficiency is to drive it around as much as possible before the test. Experts recommend that you reach highway speed on a regular basis during the last two weeks before the test. That way, you’ll be able to heat up the catalytic converter and burn any unwanted residue, so it’ll be clean before the start of the test.
Make sure your vehicle’s tire pressures are correct, especially if you own a car that was manufactured before 1999. If that’s the case, the test will involve it being driven on a dynomometer so it’s important that the tire pressures are correct and the vehicle’s tires are properly inflated.
Finally, it’s a good idea to avoid or postpone the test for now, if you’re suspecting that the vehicle is not operating at peak efficiency. Take it to a mechanic, or you can look in your area to find muffler shops near me for convenience prior to the test for a full check-up. Ask if there is anything you have to do before the test, and avoid wasting your money on a smog check just yet, if repair assistance will be needed first.
