2016 Lexus NX 200t Check Engine Light Codes

Common diagnostic trouble codes for the 2016 Lexus NX 200t often include P0300 (random/multiple misfires), P0420 (catalyst system efficiency low), P0171/P0174 (system too lean), and O2 sensor-related codes. Left untreated, P0300 can lead to damaged catalytic converters and poor fuel economy; repairing early avoids costly replacements and preserves engine health.
