2023 Toyota Prius Check Engine Light Reset

The check engine light reset on a 2023 Toyota Prius should be handled with care: a simple code clear removes the lamp but not the underlying issue. At Herb Chambers Toyota of Boston, we begin with a complete system scan to capture pending and stored trouble codes, then perform targeted repairs using OEM parts and Toyota-approved procedures. Resetting the light without addressing the root cause can mask problems that grow more expensive and dangerous over time; our technicians explain each code, show findings, and recommend the correct repairs to restore reliability and fuel efficiency. Transparency is central to our process — you’ll receive clear estimates, timeline options, and warranty information. Because many warranty conditions require certified-dealership service, performing resets and any subsequent repairs here preserves coverage. Take advantage of current service specials and flexible service financing, then schedule service online to reserve an appointment with minimal wait time.

2023 Toyota Prius Check Engine Light Codes

In Boston, drivers bring their 2023 Toyota Prius to Herb Chambers Toyota of Boston for common codes such as P0420 (catalyst efficiency), P0130–P0167 (oxygen sensor), P0455 (evaporative leak), and hybrid-specific codes that relate to the battery or inverter. Each code carries a cost implication: an unresolved oxygen sensor can reduce fuel economy and damage the catalytic converter; an evaporative leak can cause failed emissions tests and reduced efficiency; hybrid-system alerts can impact drivability and, if ignored, lead to costly component replacement. Our factory-trained technicians diagnose the precise cause with OEM diagnostics and provide a detailed estimate so you can weigh repair choices. Choosing the dealership delivers value — immediate diagnostics, genuine parts, warranty-backed repairs, and technicians experienced with Prius hybrid systems who reduce repeat visits.
