Check Engine Light Flashing

The check engine light flashing in a 2022 Lexus LC 500 signals a potentially severe misfire or an issue that could damage the catalytic converter if driven further.

At Park Place Lexus Grapevine in Grapevine, TX, our factory-trained technicians prioritize safety and long-term value: we perform rapid diagnostics using Lexus OEM software, identify whether the condition requires a tow or can be safely driven at low speed, and provide a clear repair plan. Choosing dealership service often yields lower lifecycle costs because we diagnose correctly the first time, install genuine parts, and protect warranty coverage. We also offer service financing to get you back on the road without delay. Check our service specials and schedule service online—if you see a flashing check engine light, contact us immediately for prioritized handling and transparent estimates.

2022 Lexus LC 500 Check Engine Light Reset

2022 Lexus LC 500 Check Engine Light Codes

Common check engine light codes for a 2022 Lexus LC 500 include oxygen sensor (P013x), catalytic efficiency (P0420), misfire codes (P0300–P0308), and evaporative system faults (P0440–P0455).
