2016 Lexus GS 200t Check Engine Light Codes

Understanding common codes for a 2016 Lexus GS 200t helps you make informed repair decisions. Typical codes include oxygen sensor failures (P013x), catalytic efficiency issues (P0420), mass airflow sensor errors (P0101), and misfire codes (P0300–P0304). Left unresolved, an oxygen sensor fault can reduce fuel economy and damage the catalytic converter — an expensive repair.

At Stevinson Lexus of Frederick, our local Lexus service center in Frederick, CO, diagnoses these codes with Lexus-grade scanners and tests the battery and charging system to rule out electrical contributors.
