2025 Chevrolet Blazer Check Engine Light Codes
Common check engine light codes for the 2025 Chevrolet Blazer often point to oxygen sensors (P013X series), catalytic converter efficiency (P0420), or misfires (P030X). Left unattended, an oxygen sensor issue can reduce fuel economy and damage the catalytic converter—costing significantly more to replace than the initial repair. A P0420 catalytic converter fault can escalate to full exhaust system replacement if ignored, while misfires can lead to rough running and long-term engine wear.
