2017 Lexus LS 460 Check Engine Light Codes

Common codes for the 2017 Lexus LS 460 include P0420 (catalyst system efficiency), P0300 (random/multiple misfires), P0171/P0174 (fuel trim lean), and oxygen sensor faults. Left untreated, P0420 can lead to failed emissions tests and catalytic converter replacement—an expensive repair that timely diagnostics can often avoid. Misfires (P0300-series) reduce power, increase fuel consumption, and can ruin the catalytic converter if driven hard; early intervention saves money and downtime. Lean condition codes may indicate vacuum leaks, fuel delivery issues, or sensor failure; each has a cost profile that grows if ignored. At Herb Chambers Lexus of Sharon our certified Lexus technicians prioritize accurate scanning, transparent estimates, and OEM repairs—delivering immediate and long-term savings. We document service history, check warranty coverage, and recommend cost-effective solutions. Use our online tools to schedule service and view current service specials to reduce repair cost while preserving performance.
