Check Engine Light Reset

Resetting the check engine light on a 2021 Toyota Camry can be simple, but a reset without diagnosis masks underlying problems that may grow into costly repairs. At Larry H. Miller American Toyota Albuquerque we explain the difference between a temporary reset and a true fix: our certified technicians use OEM-grade scanners to read and interpret codes, confirm whether a temporary condition cleared, and test drive to ensure sensors return to proper operation. Choosing the dealership for a reset gives you warranty-safe service, original equipment parts, and documented repairs that preserve resale value. We also provide transparent estimates showing immediate savings — such as avoiding repeated independent shop visits — and long-term savings by preventing secondary damage to catalytic converters, ignition systems, and fuel components. If a simple reset is the right step, we’ll perform it and show you the cleared codes; if repair is required, we’ll supply a clear plan, OEM parts, and options including service financing. To get started, schedule service and ask about our current service specials to maximize value.
