2022 Lexus LS 500 Check Engine Light Codes

In Frederick, CO, Stevinson Lexus of Frederick routinely diagnoses the most common trouble codes for the 2022 Lexus LS 500. Typical codes we see include P0420 (catalyst system efficiency), P0171 (system too lean), P0300–P0308 (cylinder misfires), and P0455 (EVAP large leak). Ignoring a P0420 can result in catalytic converter damage — a repair that often reaches into the thousands — while unresolved misfires can harm pistons, rings, and the catalytic converter and significantly reduce fuel economy. EVAP leaks are usually inexpensive if caught early but will cause emissions test failure if left unattended. Our Lexus-certified technicians use OEM diagnostic tools to identify the exact cause, provide a clear estimate, and explain the immediate and long-term cost benefits of timely repair. Choosing Stevinson Lexus of Frederick ensures precise work, OEM parts, and a service history that protects resale value. Ready to protect performance? schedule service and check service specials.
