2022 Lexus LC 500 Convertible Check Engine Light Flashing

A flashing check engine light in your 2022 Lexus LC 500 Convertible commonly signals an active misfire or a condition that risks catalytic converter damage. When the light flashes, it often means unburned fuel is entering the exhaust — that can overheat and destroy the catalytic converter if driven. Immediate attention is critical: stop driving if you notice poor running, loss of power, or strong fuel smell. Tow to Nalley Lexus Smyrna so our factory-trained technicians can perform a full diagnosis with OEM equipment. Rapid repair at a certified dealership helps prevent expensive downstream failures, preserves warranties, and minimizes long-term ownership costs.

2022 Lexus LC 500 Convertible Check Engine Light Reset

Resetting the check engine light without addressing the root cause only clears the symptom, not the problem. For a 2022 Lexus LC 500 Convertible, our team uses Lexus-specific diagnostic tools to read and clear codes, verify repairs, and reset learned parameters correctly. DIY resets or generic scanners can mask intermittent faults and lead to recurring faults or warranty issues. Having Nalley Lexus Smyrna complete the service ensures repairs are done with OEM parts and factory procedures, which often saves money over time by preventing repeated diagnostics and incorrect fixes. If a repair is warranty-covered, it must be performed at a certified dealership to retain coverage.

2022 Lexus LC 500 Convertible Check Engine Light Codes

The most common codes for a 2022 Lexus LC 500 Convertible include misfire codes (P0300–P0308), catalyst efficiency (P0420), fuel trim problems (P0171/P0174), and evaporative system faults (P0440–P0455).

Timely dealer diagnostics pinpoint the cause, limiting repair scope and cost.

Warranty-covered repairs must be completed at a certified dealership to ensure coverage.
