Check Engine Light Flashing
A flashing check engine light on a 2020 Toyota Prius signals a potentially severe condition and should prompt immediate attention. A flashing indicator often means the engine is misfiring, which can allow unburned fuel into the exhaust and quickly damage the catalytic converter — a costly repair if left unattended. At Nalley Toyota Union City in Union City, GA, our technicians use factory diagnostic tools to determine whether the flashing code demands towing, limp-home mode, or immediate repair. We prioritize safety and cost-effectiveness: diagnosing quickly, providing transparent estimates, and recommending OEM parts to maintain performance and emissions compliance. We also highlight ways proper, timely service saves money over time by preventing secondary damage. Check our current service specials and contact our service team or schedule service online to get prompt attention — if the light is flashing, don’t delay.
2020 Toyota Prius Check Engine Light Codes
The most frequent check engine codes for a 2020 Toyota Prius encountered at Nalley Toyota Union City include emissions-related codes such as oxygen sensor faults, P0420-type catalyst efficiency alerts, and hybrid system notifications. Each carries different consequences: oxygen sensor faults reduce fuel efficiency and increase emissions, potentially causing higher long-term fuel costs; an unresolved catalyst issue can escalate to a full converter replacement, which is significantly more expensive than early intervention; hybrid system codes may signal battery or inverter concerns that need certified diagnostics. Our certified technicians explain code severity, outline repair options, and show how proactive repairs save money over time. We provide OEM parts, genuine Toyota diagnostics, and service financing so you can address issues now and pay later. For local drivers in Union City, GA, Nalley Toyota Union City delivers convenient, trustworthy service with clear pricing and comfortable amenities — check our service specials and schedule appointment today.

Our process uses OEM scan tools, documents the repair, and ensures warranty integrity — repairs covered under warranty must be performed at a certified dealership to remain valid. We emphasize transparent estimates, OEM parts, and technician training to preserve vehicle reliability and resale value. If reset is appropriate, we’ll clear codes and run readiness tests so you leave with confidence.
