Check Engine Light Reset

Resetting the check engine light on a 2018 Honda Clarity can seem straightforward, but a simple reset without a proper diagnostic risks masking underlying issues and voiding warranty coverage.

We also offer service financing so you can address repairs immediately and pay over time, plus rotating service specials to lower out-of-pocket expense.

2018 Honda Clarity Check Engine Light Codes

Common check engine light codes for a 2018 Honda Clarity often relate to emissions sensors, EV drive battery notifications, and fuel system or catalytic converter efficiency. Examples include oxygen sensor or O2-related codes, EV inverter or battery hybrid-related alerts, and misfire or fuel trim flags. If left unaddressed, O2 sensor failures can reduce fuel economy and cause long-term catalytic converter damage—costing hundreds to replace. Hybrid battery or inverter notifications may lead to reduced electric range and higher operating costs if not diagnosed promptly. At Coggin Deland Honda we explain potential costs and outcomes upfront: early diagnostics preserve efficiency and prevent bigger repairs, delivering immediate and long-term savings compared with repeat work. Our technicians use Honda-approved tools to pinpoint codes and recommend OEM parts for lasting repairs. We emphasize convenience with online scheduling, clear estimates, and prioritized service lanes.

Our certified technicians prioritize flashing-light diagnostics, using dealer-level tools to capture transient events and hybrid-specific codes that independent shops may miss.
