2022 Lexus LS 500 Check Engine Light Codes
Common check engine light codes for a 2022 Lexus LS 500 include P0300 (random/multiple misfires), P0420 (catalyst efficiency below threshold), P0171/P0174 (system too lean), and oxygen sensor-related codes. Left unaddressed, misfires can damage the catalytic converter — a repair that can be far more costly than fixing ignition coils or spark plugs early. A P0420 can indicate catalyst wear or sensor failure; delaying diagnosis risks failed emissions tests and higher repair bills. At Park Place Lexus in Plano, TX, our certified technicians use factory-grade tools to identify whether a code reflects a sensor issue, wiring, or a mechanical concern and then recommend the most cost-effective, warranty-compliant repair. We emphasize the convenience of OEM parts, quick turnaround, and a customer-first experience including comfortable waiting areas and transparent estimates. When you choose our dealership, you get expert diagnosis, documented service history, and the confidence that repairs are backed by manufacturer standards.
