2025 Toyota 4Runner Check Engine Light Reset

Resetting the check engine light on a 2025 Toyota 4Runner is sometimes simple but should only be done after diagnosing the underlying cause. At Larry H. Miller Toyota Peoria, we use OEM scanners to read and clear codes properly, ensuring a true repair rather than masking symptoms. A reset without repair can erase useful diagnostic history and lead to missed faults, repeat visits, and higher lifetime costs. Our approach emphasizes transparency: we provide a clear explanation of codes, a written estimate, and an explanation of warranty coverage. Using OEM parts and manufacturer-recommended procedures means repairs last longer and maintain factory warranties; any warranty-covered repair must be performed at a certified dealership to remain valid. We also offer service financing to make necessary repairs accessible. For honest diagnostics, available discounts, and certified work, please explore our service specials and schedule service today.

Miller Toyota Peoria in Peoria, AZ our certified technicians evaluate codes, estimate repair costs, and explain short- and long-term savings.
