Check Engine Light Flashing

The check engine light flashing in a 2025 Dodge Hornet indicates an active misfire or condition that could rapidly damage the catalytic converter or other engine components. A flashing signal is more urgent than a steady light: it suggests unburned fuel is entering the exhaust stream, which increases emissions and the risk of expensive downstream repairs. At Larry H. Miller Chrysler Dodge Ram FIAT Denver in Denver, CO, our technicians prioritize flashing-light cases and use factory diagnostic procedures and OEM parts to identify root causes quickly—spark plugs, ignition coils, fuel injection faults, or sensor failures are common culprits. Bringing your Hornet in promptly not only protects drivability but also reduces long-term costs by avoiding catalytic converter replacement and additional engine damage. We combine transparent estimates, certified training, and same-day service workflows so many urgent issues are diagnosed and addressed fast. To protect your investment and warranty, schedule service now, and review our current service specials to maximize savings; ask about our service financing for immediate repairs with manageable payments.

2025 Dodge Hornet Check Engine Light Codes

Common OBD-II codes for the 2025 Dodge Hornet that bring drivers to Larry H. Miller Chrysler Dodge Ram FIAT Denver include P0420 (catalyst system efficiency below threshold), P0300–P0304 (random or cylinder-specific misfires), P0440 (evaporative emission control system fault), and P0135 (oxygen sensor heater circuit). Ignoring these codes can escalate costs: a loose gas cap that triggers an EVAP code is low-cost to fix, while prolonged misfires can damage the catalytic converter—turning a modest repair into thousands of dollars in parts and labor. Our Denver service center explains the cost-benefit of timely repairs: fixing a sensor or ignition coil early restores fuel economy and performance, saves on fuel and future parts, and maintains vehicle resale value. The certified technicians at Larry H. Miller use OEM diagnostics and parts, preserving warranty coverage and ensuring precise repairs. We also provide clear pricing, useful maintenance recommendations, and options like service financing and current service specials, making it simple and affordable to do the right thing for your Hornet.
