2023 Toyota Camry Check Engine Light Codes

Common check engine light codes for a 2023 Toyota Camry include P0420 (catalytic converter efficiency), P0171/P0174 (fuel trim lean), P0300–P0304 (misfires), P0130–P0167 (oxygen/air-fuel sensors), and codes related to EVAP or emissions components. Ignoring these codes can increase fuel consumption, reduce performance, and lead to costly repairs such as catalytic converter replacement or engine damage.
