2016 Lexus LS 460 Check Engine Light Reset

Resetting the check engine light on a 2016 Lexus LS 460 may seem simple, but a reset without proper diagnosis can mask the real problem and lead to more costly repairs. At Stevinson Lexus of Frederick in Frederick, CO, our approach begins with a full OEM-compliant scan to retrieve and interpret diagnostic trouble codes, inspect live sensor data, and confirm any pending or stored codes. We explain each code in plain language, outline repair options, and provide an accurate estimate before any work begins. Using genuine Lexus parts and factory procedures ensures repairs resolve the root cause — not just the symptom — and helps preserve your vehicle’s warranty. Our technicians are Lexus-certified and trained on the LS platform, so you receive precise repairs that restore performance and fuel efficiency. We maintain transparent pricing, offer service financing so you can address urgent repairs now and pay later, and point you to available service specials for additional savings.

2016 Lexus LS 460 Check Engine Light Codes

Common check engine light codes for the 2016 Lexus LS 460 include oxygen sensor faults (often P013x/P014x), catalytic efficiency issues (P0420), fuel trim or lean/rich conditions (P0171/P0172), and misfire codes (P0300–P0308). Left unaddressed, an oxygen sensor fault can reduce fuel economy and eventually damage the catalytic converter — a repair that can escalate into the low thousands of dollars. A P0420 code left untreated typically leads to reduced emissions performance and potential costly catalyst replacement. Misfires can damage pistons and catalytic components if driven extensively, multiplying repair costs. At Stevinson Lexus of Frederick we focus on early detection to minimize repair expense and downtime. Our Lexus-certified technicians use factory diagnostics to identify whether a code stems from a replaceable sensor, an intake/exhaust leak, or a deeper mechanical issue. We provide clear, itemized estimates and highlight the immediate and long-term savings of timely dealer service. Take advantage of our service specials and expert guidance — schedule service online to get a reliable diagnosis and preserve your LS 460’s performance.
