The catalytic converter cleans up the exhaust before it leaves the tailpipe. When it stops working the check engine light comes on and the vehicle will not pass emissions. We diagnose and replace catalytic converters for drivers throughout Albuquerque and the surrounding area, including Rio Rancho, Corrales, and Los Ranchos de Albuquerque — including repairs after a converter has been stolen.

- Diagnosis of catalyst-efficiency codes (P0420, P0430)
- Upstream and downstream oxygen sensor testing
- Exhaust back-pressure and flow testing

Signs You May Need Catalytic Converter Service
A check engine light with a catalyst code, a failed or borderline emissions test, a sulfur or rotten-egg smell from the exhaust, a rattle from under the car, or a sudden loud roar and loss of power after a theft. Our warning light guide and guide to exhaust rattles and smoke cover the warning signs.
Why the Converter Failed Matters
A converter rarely just wears out. Engine misfires, burning oil, or a rich fuel mixture can overheat and poison it — and would do the same to a new one. We look for that underlying cause before quoting a replacement so the repair actually lasts.
Frequently Asked Questions
Can I pass emissions with the check engine light on? No. In Bernalillo County an illuminated check engine light is an automatic emissions failure regardless of the tailpipe readings. The code has to be diagnosed and repaired first.
My catalytic converter was stolen — can you help? Yes. We replace stolen converters and can add a shield or cage that makes the replacement much harder to cut out.
