2015 Chevrolet Colorado Check Engine Light Codes

At Larry H. Miller Casa Chevrolet in Albuquerque, NM, we see a consistent set of check engine light codes on the 2015 Chevrolet Colorado: P0420 (catalyst efficiency low), P0171 (system too lean), P0300 (random/multiple cylinder misfire), P0442 (EVAP small leak), and sensor-related codes such as P0135 (oxygen sensor heater). Left unchecked, these issues can escalate: a persistent misfire (P0300) can destroy the catalytic converter and quickly push repair costs into the thousands, while a lean condition (P0171) can mean reduced fuel economy and accelerated wear on engine components. An unresolved EVAP leak may cause failed emissions tests and repeated trips to the shop. At our dealership, we diagnose codes with dealer-grade tools and explain associated costs and timelines before any work begins. Choosing our factory-trained technicians offers immediate and long-term savings — accurate diagnostics avoid unnecessary parts replacements and repeated labor. We use OEM parts to ensure proper fit and longevity, and warranty-covered repairs must be completed here to maintain coverage. To make service convenient, schedule service online or browse current service specials to lower your out-of-pocket cost.
