Check Engine Light Flashing

When the check engine light is flashing on your 2018 Honda Clarity, it typically indicates an active misfire or other condition that can rapidly damage the catalytic converter and reduce hybrid system performance. A flashing light is more urgent than a steady indicator — every minute matters for preventing costly downstream repairs. At Coggin Honda Saint Augustine in Saint Augustine, FL, our certified Honda technicians are trained to diagnose both gasoline engine and electrified system faults quickly using OEM diagnostic tools. We’ll evaluate engine misfire codes, fuel delivery, ignition components, and hybrid-system interactions to determine whether immediate repair or towing is required. Choosing our dealership ensures transparent pricing, factory parts, and warranty protection; we also offer service financing so you can get critical work done now and pay over time. Be sure to review our current service specials for savings, and schedule service online to get prioritized attention from technicians who understand the 2018 Honda Clarity’s unique plug-in hybrid systems.

2018 Honda Clarity Check Engine Light Reset

Resetting the check engine light on a 2018 Honda Clarity can be straightforward, but it’s only a short-term fix unless the underlying issue is resolved. A proper reset requires reading and clearing stored trouble codes with a factory-grade scanner, verifying repairs, and confirming no pending faults reappear. At Coggin Honda Saint Augustine our approach emphasizes diagnostic accuracy and lasting results: we identify root causes, recommend OEM parts, and provide transparent estimates that often cost less than independent shops once you factor in longevity and warranty coverage. Performing resets without addressing the cause risks masking problems that could lead to catalytic converter, hybrid battery, or drivetrain damage. When you entrust us with service, you get Honda-trained technicians, factory tools, and repair documentation that preserve warranty status. We also provide service financing and rotate service specials to help manage costs. To ensure the reset is permanent and covered properly, schedule appointment with Coggin Honda Saint Augustine and learn about our current service specials.

2018 Honda Clarity Check Engine Light Codes

Owners of the 2018 Honda Clarity in Saint Augustine commonly see codes ranging from P0300 (random/multiple cylinder misfires) and P0420 (catalyst system efficiency) to hybrid-related codes that begin with P0A or P1A indicating battery or inverter issues.
