Call (817) 652-2690What is a Catalytic Converter? (Emissions Control)
The catalytic converter is an emissions control device that converts harmful exhaust gases into less harmful substances. It uses precious metals (platinum, palladium, rhodium) as catalysts to transform carbon monoxide, hydrocarbons, and nitrogen oxides into carbon dioxide, water, and nitrogen.
Catalytic converters fail from contamination, overheating, or physical damage. Oil burning, coolant leaks, and rich fuel mixtures coat the catalyst and reduce efficiency. Overheating from misfires can melt the substrate. They're also targeted by thieves for their precious metal content.
At E1 Auto Care, we diagnose catalyst problems properly before recommending replacement. P0420/P0430 codes don't always mean bad converters—oxygen sensor issues, exhaust leaks, and engine problems can trigger these codes. We find the root cause first.

Our Catalytic Converter Replacement Process
Scan for diagnostic trouble codes (DTCs)
Analyze oxygen sensor data (upstream vs. downstream readings)
Check for exhaust leaks that could affect sensor readings
Verify no misfires or other engine problems causing converter damage
Catalyst efficiency codes (P0420/P0430) don't always mean bad converters. We check O2 sensor function, exhaust leaks, and engine health first. Replacing a converter when the real problem is an O2 sensor or exhaust leak wastes your money.

If replacement needed, select correct converter type (CARB/EPA compliant)
Remove old converter and inspect exhaust pipes
Install new converter with new gaskets and hardware
