Check Engine Light Flashing

A flashing check engine light in a 2021 Lexus ES 250 indicates a severe misfire or condition that could damage the catalytic converter or compromise safety.

Our Lexus-certified technicians perform rapid, OEM-calibrated inspections to isolate causes such as ignition faults, fuel delivery problems, or sensor failures.

2021 Lexus ES 250 Check Engine Light Codes

Common check engine codes on the 2021 Lexus ES 250 include P0420 (catalyst efficiency), P0171/P0174 (fuel trim lean conditions), P0300–P0304 (misfires), and various oxygen or mass air flow sensor codes.
