Failed Emissions Test?

Info and links regarding failed emissions tests and getting your vehicle repaired so it will pass its test.

The State makes the rules on emissions testing, and you must get your car tested through a regulated, State-run facility.


If your vehicle fails that regulated emissions test

That’s where we come in. We’re an emissions-certified repair shop with emissions certified technicians (trained and authorized) to repair the needed fixes in order for your car to pass that test.

Failure components

Most common components that cause emissions test failures that we see are O2 (oxygen) sensor codes, catalytic converter codes and evaporative systems codes.

The report generated by the State testing location notes the necessary codes that give us, the certified technicians, a place to begin to do more testing to get to the root cause of the failure.

The report does not spell out what the problem actually is with the car, but it does give us a starting point for testing and detecting the cause.

If emissions parts have been removed from the car

Let’s say that, for some reason, your vehicle no longer has emissions parts on it.

When it comes to emissions testing, that vehicle must pass the emissions test on its own. And there’s just no way around that.

So, if it passes, great, you’re good to go.

But what if the vehicle fails?

If it fails, your vehicle will need to be fixed in order to pass the emissions test.

The first thing we’d recommend is installing the missing emissions components. Once all emissions components are back on the vehicle if you still don’t pass the test you would have the ability to apply for a State-regulated waiver.

Costs of repairs

The costs for these repairs range and truly depend on what has failed, and the quality and frequency of the regular vehicle maintenance.

As a general rule, good maintenance is always going to cost you less in the long run. One caveat to keep in mind on that general rule: the length of time you plan on keeping that car.

If the costs to fix your vehicle are more than what you can afford, the State does have a waiver program that you may potentially qualify for, as long as you are working with a State-certified repair shop, with State-certified technicians, have paid at least $150 to cover the cost of testing or repairs, and all of the emissions parts are still intact and installed on your vehicle.

We can talk more about this inside the shop, if needed. Or, check out the parameters on the requirements and waiver protocols from the State.

Emissions & Check Engine Lights
