Check Engine Light Flashing

The check engine light flashing on your 2016 Lexus ES 350 is an urgent warning that the engine is misfiring or experiencing a condition that could damage the catalytic converter. When this happens, immediate attention at Park Place Lexus in Plano, TX is essential: our certified technicians will prioritize safety, inspect ignition components, fuel delivery, and emissions systems using factory diagnostic tools, and identify whether a simple tune-up, coil or spark plug change, fuel system clean, or a more involved repair is necessary. Leaving a flashing light unaddressed risks higher repair bills, reduced performance, and potential failure of emissions equipment. To help owners act quickly we provide transparent estimates, OEM parts, and the option of service financing so you can address critical repairs immediately and pay over time. We frequently run seasonal service specials for reduced labor or bundled diagnostics; check current offers and schedule appointment to protect your vehicle and avoid catalytic converter damage. Our team will explain coverage, warranty implications, and long-term savings from timely, certified repairs.

2016 Lexus ES 350 Check Engine Light Reset

Resetting the check engine light on a 2016 Lexus ES 350 should be performed after properly diagnosing and repairing the underlying issue. At Park Place Lexus in Plano, TX, we emphasize repair over simple resets because clearing a code without fixing the cause can allow damaging conditions to persist and may void warranty protections. Our technicians follow Lexus-recommended procedures: they retrieve codes with OEM scanners, resolve the root cause using genuine parts, and then verify the repair by test driving and re-scanning the system before a safe reset. Choosing dealership service delivers transparency on work performed, documented repairs for warranty records, and certified technicians who can implement factory fixes that extend component life and vehicle resale value. We also provide service financing and package discounts; review our service specials and schedule service online for a convenient appointment. Trusting Park Place Lexus ensures the reset is permanent, correct, and backed by dealer expertise.

2016 Lexus ES 350 Check Engine Light Codes

Common check engine light codes for the 2016 Lexus ES 350 include P0420 (catalyst system efficiency low), P0135 (O2 sensor heater circuit), and P0300 (random/multiple cylinder misfire). Each code has cost implications: ignoring P0420 can lead to expensive catalytic converter replacement; untreated P0135 or faulty oxygen sensors reduce fuel economy and accelerate emissions system wear; recurring misfires like P0300 can damage pistons, catalytic converters, and increase fuel consumption. At Park Place Lexus in Plano, TX, our certified technicians diagnose codes accurately with OEM tools and explain the repair path, parts required, and both immediate and long-term savings from timely fixes. We often deliver lower overall costs than independent shops because accurate diagnostics and OEM parts prevent repeat work and protect performance.
