A failed emissions test usually comes down to a warning light, an emissions component that is not doing its job, or monitors that have not reset since a recent repair. We diagnose and repair emissions failures for drivers throughout Albuquerque and the surrounding area, including Rio Rancho, Corrales, and Los Ranchos de Albuquerque, so you can get back to an Air Care station and pass.
What's Included
- Full diagnostic scan and review of your test failure report
- Check engine light diagnosis and repair
- Oxygen sensor, EVAP, and EGR system service
- Catalytic converter diagnosis and replacement
- Gas cap and EVAP leak testing
- Drive-cycle and readiness monitor completion so the vehicle is ready to re-test
Common Reasons a Vehicle Fails
An illuminated check engine light (an automatic failure here), incomplete readiness monitors after a battery disconnect or recent repair, high tailpipe readings from a worn converter or a rich mixture, or a failed EVAP (gas cap and fuel vapor) check. Our dashboard warning light guide is a good starting point.
A Note on Readiness Monitors
If your battery was disconnected or trouble codes were recently cleared, the vehicle’s self-check monitors may not be finished running. That alone can cause a failure even with nothing wrong. We can complete the drive cycle or tell you exactly how to.
Frequently Asked Questions
Which vehicles need an emissions test in Albuquerque? Generally, gas vehicles roughly 4 to 35 model years old, registered in Bernalillo County, and under about 10,000 lbs. Fully electric and diesel vehicles are exempt. Testing is required every two years and whenever the vehicle changes owners.
Do you perform the emissions test itself? We focus on the diagnosis and repair side. Once we have fixed the cause of the failure and the readiness monitors are set, you can take the vehicle to any Air Care station to pass.
What are the most common reasons a vehicle fails emissions? A lit check engine light is an automatic fail regardless of the readings. Beyond that, common causes are oxygen sensor faults, a failing catalytic converter, EVAP leaks (often a gas cap or purge valve), engine misfires, and EGR problems.
My check engine light is off but I still failed — why? If the light was cleared recently, the vehicle's readiness monitors may not have finished running. The test station reads that as “not ready” and won't pass the vehicle until the monitors reset through normal driving.
Will clearing the code get me through the test? No, and it usually backfires. Clearing codes resets the readiness monitors, so the vehicle fails for “not ready” until it's driven enough to complete them. Fixing the underlying cause is the only reliable path.
How long does emissions repair take? It depends on the cause — a purge valve or sensor is often same-day, while a catalytic converter or a wiring repair takes longer. After the repair we make sure the monitors are set so you can pass on the first try.
