Check Engine Light Flashing

The check engine light flashing on a 2026 Toyota Prius indicates an active misfire or a serious condition that can damage the catalytic converter or hybrid components if driven further. In Murray, UT, Larry H. Miller Toyota Murray advises you to stop driving when safe and have the vehicle towed or transported to our service center for immediate inspection. Our technicians use Toyota-specific diagnostic equipment to isolate misfires—whether they stem from spark or ignition issues, fuel delivery, or hybrid system faults. A flashing light often requires prioritized attention: delaying repair increases the chance of converter damage, reduced efficiency, or accelerated wear on the hybrid powertrain. We provide a clear estimate before repair, use OEM parts to preserve performance and warranty coverage, and offer service financing so you can get repairs done immediately and pay over time. Check our current service specials and schedule service online to secure a prompt appointment and keep your Prius running as designed by Toyota.

Our certified technicians explain why dealer-performed resets using OEM tools provide a complete repair history and help maintain warranty integrity—repairs covered under warranty must be completed at a certified dealership.

2026 Toyota Prius Check Engine Light Codes

Common check engine codes for the 2026 Toyota Prius include oxygen sensor faults (P0130–P0167), catalytic efficiency issues (P0420), and hybrid system-related codes that require Toyota-specific analysis. Each code has cost implications if left unresolved: oxygen sensor failures increase fuel consumption and can damage the catalytic converter, leading to significant replacement costs; catalytic converter failures are expensive and can be avoided with timely repair; hybrid-related sensor issues can reduce regenerative braking efficiency and strain the hybrid battery. At Larry H. Miller Toyota Murray in Murray, UT, our factory-trained technicians interpret each code in the context of the Prius hybrid system and recommend the most cost-effective and lasting solution. We emphasize the immediate and long-term savings of doing business with our dealership: correct diagnosis, OEM parts, and warranty-backed repairs often cost less over time than repeated, incomplete fixes.
