2025 Nissan Sentra Check Engine Light Codes

The most common codes for a 2025 Nissan Sentra involve O2 sensors (P0130–P0167), EVAP leaks (P0440–P0456), and misfire codes (P0300–P0312). Left unaddressed, these translate to decreased fuel economy, higher emissions, catalytic converter damage, and costly repairs. For example, an unresolved misfire can rapidly increase exhaust temperatures and ruin the catalytic converter, a repair that can be several times the cost of the initial fix. At Larry H. Miller Nissan Mesa we diagnose codes quickly, explain implications, and recommend OEM repairs that protect vehicle longevity and resale value. Our dealership often costs less than independent shops when factoring in accurate diagnostics, OEM warranties, and long-term reliability savings.
