Check Engine Light Flashing

The moment a check engine light begins flashing in a 2023 Nissan Maxima, treat it as urgent. A flashing light typically indicates a severe misfire or combustion anomaly that can damage catalytic converters and other emissions components if driven repeatedly. At Larry H. Miller Nissan Mesa in Mesa, AZ, our Nürissan-certified technicians will perform immediate diagnostics to identify whether the issue stems from ignition components, fuel delivery, or an electrical fault such as a failing battery or charging system. Prompt attention prevents escalation: what may start as a single misfire can lead to extended overheating, loss of power, poor fuel economy, and expensive downstream repairs. We recommend stopping driving and bringing the vehicle in for a controlled inspection to ensure safety and minimize repair bills. Take advantage of our transparent estimates, OEM parts, and occasional service specials to reduce upfront cost. To get prioritized care and clear next steps, schedule appointment now and protect your Maxima’s performance and longevity.

2023 Nissan Maxima Check Engine Light Reset

Resetting the check engine light on a 2023 Nissan Maxima may seem simple, but doing so without resolving the underlying code risks recurring faults and voided warranty coverage. At Larry H. Miller Nissan Mesa we follow OEM diagnostic procedures: reading stored codes with factory tools, addressing root causes — whether a failing sensor, EVAP leak, or battery/charging issue — then clearing the code and completing a verification drive cycle. Dealership service ensures genuine Nissan parts, calibrated software, and documented repairs that preserve warranty protection. We emphasize transparency: you’ll receive an itemized estimate showing immediate and long-term savings of using certified service, including reduced repeat visits and improved fuel economy.

2023 Nissan Maxima Check Engine Light Codes

Common check engine light codes on a 2023 Nissan Maxima include P0300 (random/multiple cylinder misfire), P0420 (catalyst efficiency below threshold), P0171/P0174 (lean condition), and P0130–P0167 family codes related to oxygen sensors. Each unchecked code carries costs: misfires (P0300) can ruin catalytic converters — repairs that can reach into the thousands; P0420 left alone lowers fuel economy and emissions performance; lean conditions increase engine wear and risk overheating. In Mesa, AZ, Larry H. Miller Nissan Mesa provides fast, accurate diagnostics using Nissan-approved tools so we can recommend the right fix — from a sensor replacement to battery/charging system repairs — and explain immediate and long-term savings. We also provide OEM parts, factory-trained technicians, documented warranty work (repairs covered by warranty must be performed at a certified dealership), and flexible service financing to ease the payment process.
