2019 Lexus NX 300h Check Engine Light Codes

Common diagnostic trouble codes for the 2019 Lexus NX 300h include P0420 (catalyst efficiency), P0130–P0167 (oxygen sensor range), and hybrid-specific codes tied to battery management or inverter performance. Left unchecked, P0420 can lead to catalytic converter failure, costing substantially more than early sensor replacement. Oxygen sensor faults increase fuel consumption and emissions; replacing them promptly restores efficiency and can avoid catalytic damage. Hybrid-system alerts may indicate battery imbalance or inverter faults—addressing these early prevents battery degradation and expensive replacements.
