2015 Lexus LS 600h L Check Engine Light Codes

In Frederick, CO and across our service center at Stevinson Lexus of Frederick, we regularly see the check engine light triggered by a handful of repeatable codes on the 2015 Lexus LS 600h L. Common diagnostic trouble codes include oxygen sensor failures (reduces fuel efficiency and can lead to catalytic converter damage if left unattended), misfire codes (risking engine damage and rough running), EV/hybrid battery or inverter codes (affecting performance and drivability), and evap system faults often caused by a loose fuel cap or purge valve failures (leading to emissions-related failures).
