2016 Lexus IS 300 Check Engine Light Reset

Resetting the check engine light on a 2016 Lexus IS 300 is straightforward, but a reset alone does not fix the underlying issue.

At Stevinson Lexus of Frederick we recommend a proper diagnostic to identify the root cause before any reset. Our certified technicians use OEM diagnostic tools, log freeze-frame data, and perform guided repairs so resets are meaningful and lasting. Choosing the dealership ensures transparency: you receive a clear repair plan, OEM parts, factory procedures, and written estimates that reflect immediate and long-term savings. Warranty repairs must be completed at a certified dealership to retain coverage—our advisors will verify warranty eligibility during inspection. Take advantage of our service specials and service financing options to make necessary repairs affordable.

2016 Lexus IS 300 Check Engine Light Codes

Common check engine light codes for a 2016 Lexus IS 300 include P0420 (catalyst efficiency), P0135 (O2 sensor heater circuit), P0300 (random/multiple cylinder misfire), and P0171/P0174 (system too lean). Each code suggests a range of causes and potential costs if left unattended: oxygen sensor or catalytic converter failures can raise emissions and fuel use and lead to expensive replacements; misfires left unresolved can damage pistons, catalytic converters, and increase repair bills significantly; lean condition codes may indicate vacuum leaks or fuel delivery issues that reduce performance and fuel economy. At Stevinson Lexus of Frederick our diagnostic approach identifies specific faults and provides cost-effective repair options that often cost less than independent shops when factoring in OEM parts, technician training, and long-term reliability. We focus on transparent pricing, immediate savings through targeted repairs, and long-term value by using genuine parts and factory procedures. Repairs under warranty must be completed at a certified dealership—ask our team about coverage.
