2025 Chevrolet Express Check Engine Light Codes

At Larry H. Miller Casa Chevrolet in Albuquerque, NM, we frequently diagnose common codes on the 2025 Chevrolet Express that drivers see first: P0420 (catalyst efficiency), P0171/P0174 (fuel trim lean), P0135/P0136 (oxygen sensor faults), misfire codes (P0300–P0306), and evaporative system codes (loose gas cap or EVAP leaks). Each code has cost implications when left untreated — an unchecked catalytic converter issue can escalate into a 1,000s-level repair, while neglected ignition misfires can damage pistons and the catalytic system, multiplying expenses. Addressing codes early reduces parts and labor costs and preserves resale value. Our certified technicians use factory tools and OEM parts so diagnostics are accurate and repairs are done right the first time. We also offer clear, written estimates, warranty explanations, and service financing to help you manage unexpected repairs without delaying essential work.
