2023 Lexus LC 500 Convertible Check Engine Light Codes

The most frequent check engine light codes seen on a 2023 Lexus LC 500 Convertible in Plano, TX, include oxygen sensor faults (P013x/P014x), catalytic converter efficiency (P0420), misfires (P030x), and evaporative system leaks (P044x). Each code carries its own cost implications: an oxygen sensor or EVAP repair is often modest compared with the cost of ignoring the issue—unresolved O2 sensor faults can damage the catalytic converter, which is significantly more expensive to replace. Misfires left unattended risk piston and catalytic damage and can lead to decreased performance and higher fuel bills. At Park Place Lexus, our certified technicians diagnose codes with OEM-grade tools and offer clear estimates so you understand upfront the immediate cost and the long-term savings of properly repairing the vehicle. Using genuine Lexus parts and factory procedures preserves warranty coverage and resale value. For convenience, amenities like loaner vehicles, a comfortable lounge, and quick turnaround help minimize disruption.
