2025 Toyota Highlander Hybrid Check Engine Light Codes

Common check engine light codes for the 2025 Toyota Highlander Hybrid include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0136 (oxygen sensor circuit), and hybrid-system related codes that require hybrid-specific diagnostics. Left unaddressed, these codes can lead to reduced fuel economy, increased emissions, and costly component failure — for instance, unresolved misfires can damage the catalytic converter, a significantly more expensive repair.
