2011 Hyundai Tucson Check Engine Light Codes

Common check engine light codes for a 2011 Hyundai Tucson include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0135 (oxygen sensor heater circuit), and P0442 (evaporative emission system small leak). Ignoring each has cost implications: unresolved P0300 leads to damaged catalytic converters and poor fuel economy; P0420 left unchecked can mean a converter replacement that can run thousands of dollars; P0135 or worn O2 sensors degrade fuel trim and shorten component life; P0442 can cause failed emissions tests and higher fuel loss. At Larry H. Miller Hyundai Peoria we explain these outcomes, provide cost-effective repair plans, and emphasize immediate and long-term savings gained by addressing issues early.
