2026 Lexus ES Check Engine Light Codes

Common check engine codes for the 2026 Lexus ES include P0420 (catalyst efficiency below threshold), P0300–P0304 (random or cylinder-specific misfires), and P0130–P0167 (oxygen sensor faults).

We provide clear price estimates, often delivering better total-value outcomes than independent shops because our repairs use manufacturer parts and trained technicians who follow Lexus repair procedures.
