All 1 Known Issues
On the 2013-2022 Nissan Sentra MR20DD, the B17 and B18 Sentra with the MR20DD engine is prone to premature catalytic converter failure, often before 100,000 miles. The converter substrate breaks down, triggering P0420 efficiency codes. Contributing factors include the direct injection engine's tendency to produce more particulates, short trip driving cycles that prevent the converter from reaching full operating temperature, and catalytic converter theft (the Sentra's low ground clearance makes it an easy target).
Common Symptoms
- Check engine light with P0420
- Reduced acceleration
- Sulfur smell from exhaust
- Failed emissions test
- Rattling from under vehicle
How to Fix
Replace the catalytic converter. OEM replacements cost $800-1,400. Aftermarket CARB-compliant converters are available for $250-500. Install a catalytic converter shield/cage ($150-300) to deter theft. Ensure the engine is running properly with no misfires or rich conditions that could damage the new converter.
