2010 Toyota Venza Check Engine Light Codes

At Larry H. Miller Toyota Peoria in Peoria, AZ we see a handful of repeat codes on the 2010 Toyota Venza that owners should know. Common codes include P0420 (catalyst system efficiency low), P0171/P0174 (lean fuel trim), P0300–P0304 (misfires), and P0135 (oxygen sensor heater). Ignoring these codes can increase emissions, reduce fuel economy, and in some cases cause permanent damage to the catalytic converter — a costly repair that can be prevented by timely diagnosis. For example, a persistent lean condition left unattended increases wear on ignition components and may lead to multiple component replacements instead of a single sensor change. Our certified technicians use OEM-grade scanners and parts to identify root causes and provide transparent cost options that often yield immediate and long-term savings compared with piecemeal repairs. We explain each code, the repair options, warranty coverage, and how dealer-performed repairs protect vehicle value. To take advantage of our efficiency and parts availability, schedule service and review current service specials before your visit.
