2011 Lexus IS 250 Check Engine Light Codes

Common diagnostic trouble codes for a 2011 Lexus IS 250 include oxygen sensor (P0130–P0167), catalyst efficiency (P0420), misfire codes (P0300–P0312), and EVAP system faults (P0440–P0455). Left unaddressed, oxygen sensor and catalyst issues lead to poor fuel economy and potential catalytic converter failure, which can cost significantly more to replace. Misfires cause rough running, increased emissions, and potential engine damage if ignored. EVAP faults often stem from loose caps or small leaks but can evolve into drivability problems. At Park Place Lexus Grapevine we diagnose codes accurately, explain the cost-benefit of timely repairs, and deliver OEM-grade fixes that preserve performance. Our certified technicians, quick service lanes, and comfortable amenities make the process efficient and cost-effective—often less costly over time than repeated independent repairs.
