2025 Toyota Grand Highlander Hybrid Check Engine Light Codes

The most common check engine light trouble codes for a 2025 Toyota Grand Highlander Hybrid in Auburn, MA, often relate to fuel mixture (O2 sensor codes), evaporative emissions leaks (loose gas cap or EVAP codes), catalytic efficiency, and hybrid system sensors.
