What to Do After a Failed Emissions Test

Renewing your vehicle tags often means you’ll have to also take your vehicle in for an emissions test so you can supply the DMV your pass certificate. But what do you do if your vehicle fails the emissions test? Don’t worry, CarAdvise is here to lend you a helping hand.

Start off by asking yourself these 3 questions:

Am I overdue for an oil change?

Dirty oil in the engine is a common cause for failing an emissions test. Dirty oil will have your engine releasing more pollutants, so get some fresh oil and get your oil changed!

Is there rattling in my engine?

Rattling in the engine could be a sign of a worn-down exhaust system. Over time, weather and general wear and tear will require you to get your exhaust system fixed. A bad exhaust is a likely culprit to a failed emissions test!

Is my check engine light on?

Check engine light on = automatic emissions test fail. Your check engine light can come on for a number of different reasons, so it’s best to get your car over to a shop as soon as you can to have your engine checked out!
