2011 Lexus HS 250h Check Engine Light Codes

Common check engine light codes for a 2011 Lexus HS 250h include P0420 (catalyst efficiency), P0300 (random/multiple misfire), and P0171/P0172 (fuel trim lean/rich). P0420 left untreated may indicate catalytic converter stress; repairing early (oxygen sensor or exhaust leak) typically costs far less than replacing the converter. P0300 misfires can accelerate internal wear and damage emissions systems—prompt repair avoids larger engine costs. Fuel trim codes often trace to vacuum leaks, sensors, or injector issues; resolving them restores fuel economy and prevents fuel system damage. At Park Place Lexus Grapevine in Grapevine, TX, our trained technicians diagnose these codes with OEM tools and present clear repair options and cost estimates. That combination of accurate diagnosis, factory parts, and dealership warranty work delivers both immediate value and long-term savings.
