2011 Lexus LS 460 Check Engine Light Reset

Resetting the check engine light on a 2011 Lexus LS 460 can be as simple as clearing the code, but that doesn't fix the underlying fault. At Stevinson Lexus of Frederick we recommend a full diagnostic so technicians can identify the root cause—whether an oxygen sensor, EVAP leak, or ignition fault—so you avoid repeat visits and larger repairs later. Dealer-performed resets are paired with proper repairs, OEM replacement parts, and warranty-backed workmanship, which protects you and maintains vehicle history. Our certified Lexus technicians document each repair and provide clear estimates, showing how correct repairs produce long-term savings by preserving fuel economy and preventing damage to emissions systems.

2011 Lexus LS 460 Check Engine Light Codes

Common check engine light codes for the 2011 Lexus LS 460 seen at our Frederick, CO service center include P0420 (catalyst system efficiency low), P0171/P0174 (system too lean), P0300–P0308 (random or cylinder-specific misfire), and P0442 (EVAP small leak). Each has different cost and risk implications: leaving a P0420 untreated can lead to poor emissions performance and eventual catalytic converter replacement—an expensive repair—while misfires can harm pistons and catalytic systems quickly. EVAP leaks can cause failed emissions tests and reduced fuel economy. At Stevinson Lexus of Frederick we diagnose codes with precision and outline repair costs and timelines so you can make an informed decision. Choosing dealership service often costs less than independent shops in the long run because we use OEM parts, maintain proper warranty records, and prevent repeat failures through correct repairs.
