Emissions testing
A pre-test check of readiness monitors and warning lights, so you know where you stand before an official test.
Emissions testing and repair
A failed test or a lit check engine light points to a specific fault. We test your vehicle, trace the cause with live data and repair only what the results call for.
Rules and test requirements differ by area, so bring the notice you received and we will work from it.

Do I need this?
Emissions faults usually announce themselves long before a test is due. Watch for these.

How we approach it
A clear process keeps repairs focused and your costs predictable.
We start with your test report or warning light and note what failed.
Scan data, sensor checks and smoke testing separate a failing part from a symptom of something else.
You get photos and a written estimate with the part, labor and warranty listed.
We clear codes, run a drive cycle so the monitors set, and confirm the vehicle is ready to retest.
The light can be off while readiness monitors are still not set, often after a battery disconnect or a recent code clear. A drive cycle usually fixes that, and we can tell you whether that is the case.
A fitted shield or cage over the converter, plus etching your vehicle ID on it, makes it a harder target. We can fit a shield when we replace a converter or at any visit.
We perform pre-test checks and the repairs behind a failed result. Official test requirements vary by area, so ask us which station applies and we will point you the right way.
Failed a test?
Tell us what the report or warning light says and pick a time. We'll confirm within one business day.
