2014 Hyundai Tucson Check Engine Light Codes

Common codes for the 2014 Hyundai Tucson include P0420 (catalyst system efficiency), P0135 (O2 sensor heater), P0300 (random/multiple cylinder misfire), and P0171/P0174 (system too lean). Left unchecked, each can lead to escalating costs: an unresolved P0420 may indicate catalytic converter damage that can cost significantly more than early sensor replacement; misfires (P0300) can damage pistons or converters; and persistent lean codes increase fuel consumption and engine wear. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our certified technicians diagnose these codes using OEM tools and provide accurate, cost-effective repair plans that prioritize durability and resale value.
