2025 Toyota Highlander Hybrid Check Engine Light Codes

The most common codes we see on a 2025 Toyota Highlander Hybrid in Boston include emissions-related oxygen sensor faults, EV/hybrid system charge anomalies, and 12V battery voltage irregularities. Left unaddressed, oxygen sensor issues can degrade fuel economy and damage the catalytic converter — a far costlier repair than addressing the sensor early. Hybrid-system codes may indicate recharge or inverter concerns; ignoring them risks reduced drivability or complete hybrid-system shutdown, escalating repair costs. 12V battery faults often trigger a cascade of warnings and can prevent the vehicle from starting. At Herb Chambers Toyota of Boston our OEM diagnostic tools isolate the exact code and cause. We explain repair options, provide transparent pricing and highlight immediate and long-term savings of timely service — including improved fuel economy, preserved hybrid battery life, and higher resale value. Take advantage of our service specials or schedule service to get expert, factory-backed repairs quickly.
