Check Engine Light Flashing

The check engine light flashing in a 2020 Nissan 370Z indicates a potentially serious misfire or condition that can damage the catalytic converter or drivetrain if driven. A flashing light is different from a steady light: it often means the engine is misfiring, causing unburned fuel to enter the exhaust. That condition raises temperatures in the catalytic converter and can quickly lead to costly repairs. At Larry H. Miller Nissan Mesa in Mesa, AZ, our certified technicians prioritize flashing-light diagnostics and will perform a comprehensive scan, compression checks, and fuel/ignition inspections to identify the root cause. We recommend stopping driving and having the vehicle towed or driven minimally to the dealership to avoid escalation. We provide transparent repair estimates stating immediate and long-term savings, ICE-certified OEM parts, and factory training that ensures repairs are done correctly the first time. Ask about our service financing to address urgent repairs now and pay over time, and check our current service specials when you schedule service.

2020 Nissan 370Z Check Engine Light Reset

Resetting the check engine light on a 2020 Nissan 370Z can be done with an OBD-II tool, but a reset without addressing the underlying fault simply masks the problem and risks further damage. At Larry H. Miller Nissan Mesa, we follow a disciplined approach: diagnose the code, repair or replace the faulty component with OEM parts when needed, and then reset the system so the vehicle runs to factory standards. This approach preserves warranty coverage and ensures the repair is permanent rather than temporary. Our technicians document codes, recommended repairs, and costs so you understand how dealership service delivers both immediate savings—by preventing repeat visits—and long-term value through correct parts and workmanship. We also honor warranty terms that require certified-dealer repairs and offer service financing for qualified customers. To arrange a transparent inspection and safe reset, schedule appointment and review current service specials.

2020 Nissan 370Z Check Engine Light Codes

Common check engine light codes for the 2020 Nissan 370Z include P0300 (random/multiple misfires), P0171/P0174 (fuel trim lean conditions), P0420 (catalyst system efficiency below threshold), and sensor codes like P0135 (oxygen sensor heater fault). Each code points to distinct risks: misfires (P0300) can ruin catalytic converters at substantial cost; lean conditions (P0171/P0174) reduce power and fuel economy; P0420 indicates potential catalyst wear that increases emissions and inspection failure risk. At Larry H. Miller Nissan Mesa, our Mesa, AZ service center uses Nissan-specific diagnostic equipment to quantify the impact, present clear repair options, and estimate costs so you can make informed decisions. Timely repair avoids compounding expenses and preserves engine performance—translating into immediate savings by preventing larger repairs and long-term savings via improved fuel economy and longevity.
