2012 Lexus IS 350 C Check Engine Light Codes

At Stevinson Lexus of Frederick, CO, our technicians frequently encounter the range of engine codes that trigger the check engine light on a 2012 Lexus IS 350 C. Common codes include O2 sensor faults (P0130–P0167 range), catalytic converter efficiency codes (P0420), and ignition misfire codes (P0300–P0306). Left unaddressed, an O2 sensor failure can shorten catalytic converter life and reduce fuel economy; catalytic issues if ignored risk complete converter failure with repair costs that can escalate into the thousands. Misfires, if not diagnosed promptly, can lead to engine damage and costly repairs. We explain each code in plain language, show the inspection and parts required, and provide a clear cost comparison that highlights how early intervention saves money immediately and over the vehicle’s lifetime. Our Frederick service center uses OEM diagnostic tools and parts, offers comfortable customer amenities, and presents transparent estimates so you understand both the repair need and the value of doing the work with certified Lexus technicians.
