2019 Nissan Maxima Check Engine Light Codes

At Larry H. Miller Nissan Mesa in Mesa, AZ, we commonly see several check engine codes on the 2019 Nissan Maxima that owners should not ignore. Typical codes include P0420 (catalyst system efficiency below threshold), P0171/P0174 (lean condition), P0300–P0306 (misfires), and oxygen sensor faults such as P0130–P0167. If left untreated, a P0420 can lead to poor fuel economy and eventual catalytic converter failure—replacement can run into the thousands of dollars compared to the modest cost of early repair. Lean condition codes often signal intake leaks or fuel delivery problems that, if ignored, can damage spark plugs and catalytic components. Misfires reduce power and can overheat the catalytic converter, dramatically increasing repair bills and reducing vehicle lifespan. Our Mesa service center provides a full explanation of code-related risks and a transparent estimate. With factory-trained technicians, OEM parts, and targeted repairs, customers gain immediate savings on labor and parts and long-term savings through improved fuel economy and fewer repeat visits. To expedite service, you can schedule service online and check current service specials.

Check Engine Light Flashing

A flashing check engine light in a 2019 Nissan Maxima is a serious warning that indicates active misfires or conditions that could rapidly harm the catalytic converter or engine. When the light flashes, drive minimally and head directly to Larry H. Miller Nissan Mesa in Mesa, AZ for immediate inspection. Flashing often signals that unburned fuel is entering the exhaust, which can overheat and destroy emission control components, leading to much higher repair costs and potentially disabling the vehicle. Our dealership prioritizes flashing conditions with rapid triage, using Nissan-specific diagnostic tools and experienced technicians to identify ignition, fuel, or sensor failures quickly. We emphasize transparent communication: you’ll receive a clear diagnosis, options with OEM part pricing, and information about warranty coverage—remember, warranty repairs must be completed at a certified dealership to stay valid. Ask about our current service specials to offset immediate costs and consider service financing to proceed without delay. For safety, reliability, and to protect your Maxima’s value, schedule appointment right away or call our service advisors at Larry H. Miller Nissan Mesa.

2019 Nissan Maxima Check Engine Light Reset

Resetting the check engine light on a 2019 Nissan Maxima is a simple action but not a substitute for a professional diagnosis. While some owners may clear a code with an OBD-II tool or by disconnecting the battery, that only erases the symptom and not the underlying cause; the light is likely to return and the true issue may worsen. At Larry H. Miller Nissan Mesa, we recommend a proper diagnostic followed by any needed repairs with OEM parts so the condition is resolved permanently and your vehicle remains protected. Our certified technicians document codes, perform root-cause repairs, and verify the system is stable before clearing codes. This approach preserves warranty coverage and long-term reliability, delivering immediate and downstream savings by preventing repeat visits and premature component failures. We maintain transparent pricing, available service specials, and service financing to make necessary repairs affordable. To ensure your Maxima is repaired correctly the first time, schedule service with our Nissan-trained team in Mesa, AZ today.
