2015 Chevrolet Tahoe Check Engine Light Codes

Understanding common check engine light codes for a 2015 Chevrolet Tahoe helps you make informed decisions. Frequent codes include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim lean), and P0135 (oxygen sensor heater circuit). Ignoring these codes can escalate repair costs: a P0420 left unattended may require catalytic converter replacement (thousands of dollars), persistent misfires (P0300) can damage pistons or catalytic systems, and unresolved lean conditions (P0171/P0174) increase fuel use and component wear. At Larry H. Miller Casa Chevrolet in Albuquerque we quickly diagnose codes, explain the consequences of delaying repairs, and recommend cost-effective, manufacturer-approved fixes. Our service offers immediate savings through precise diagnostics and long-term savings by using OEM parts and certified procedures that preserve performance and resale value.
