Check Engine Light Flashing

A flashing check engine light on your 2016 Lexus IS 350 often indicates a severe misfire that can damage the catalytic converter or lead to immediate drivability problems. In Plano, Park Place Lexus responds quickly — our certified technicians prioritize flashing-light cases because they can escalate rapidly. A flashing light commonly means unburned fuel is entering the exhaust, raising temperatures and risking expensive converter damage. Left unchecked, the cost can climb from a simple ignition coil or spark plug change to a full catalytic converter replacement, which is substantially more expensive and more time-consuming. We offer straightforward, factory-backed diagnostics that pinpoint root causes, and we use OEM parts to restore the precise calibration your Lexus requires. Take advantage of our service specials, and ask about service financing to manage unexpected repairs. For safety and to protect long-term value, schedule service immediately or contact Park Place Lexus Plano for guidance.

2016 Lexus IS 350 Check Engine Light Reset

Resetting a check engine light on a 2016 Lexus IS 350 may seem simple, but clearing codes without repairing the root cause can hide recurring problems and void warranty protections. At Park Place Lexus Plano, we perform complete diagnostics and document required repairs before any reset. This transparent approach ensures permanent fixes using OEM parts and factory procedures. Our technicians are Lexus-trained and certify repairs to support warranty claims — remember that repairs covered under warranty must be done at a certified dealership to remain valid. Resetting is part of the service, but our priority is long-term reliability: correct repairs save money over time compared with temporary fixes. We also provide clear pricing, available service specials, and service financing so you can address issues now and spread payments. To protect your vehicle and maintain peak performance, schedule appointment with Park Place Lexus Plano and let our team handle diagnostics, repairs, and the final reset professionally.

2016 Lexus IS 350 Check Engine Light Codes

Common codes for a 2016 Lexus IS 350 include P0420 (catalyst efficiency), P0300–P0306 (misfires), P0171/P0174 (fuel trim issues), and P0135 (oxygen sensor heater circuit). In Plano, Park Place Lexus interprets these codes and explains the real-world risks and costs if left unaddressed. For example, ignoring P0420 can lead to catalytic converter failure—often thousands of dollars in repair—whereas early diagnosis usually requires only sensor replacement or minor exhaust repairs. Treating misfire codes early saves on fuel, protects the exhaust system, and prevents cascading damage to ignition components. Our Lexus-certified team provides fast diagnostics, transparent estimates, and OEM parts to correct issues the right way. Choosing Park Place Lexus often means lower total ownership costs: immediate savings through accurate diagnosis and long-term savings by avoiding repeat trips and premature component failure.
