Check Engine Light Flashing

The check engine light flashing in a 2022 Nissan Maxima is an urgent signal that engine misfires are occurring and unburned fuel may be entering the exhaust stream. Continued driving under these conditions can rapidly overheat and damage the catalytic converter — a costly repair — and can also reduce engine performance and fuel economy. At Larry H. Miller Nissan Mesa in Mesa, AZ, our factory-trained technicians prioritize flashing conditions and perform priority diagnostics to protect your vehicle. We use OEM diagnostic tools to read codes, inspect ignition coils, spark plugs, fuel injectors, and exhaust sensors, and we explain every recommended repair so you understand immediate and long-term benefits. Taking prompt action at our dealership often saves money versus delayed or incorrect fixes and preserves warranty coverage, which requires certified-dealership service. If your light is flashing, don’t delay — schedule service online now and check current service specials to reduce cost and downtime.

2022 Nissan Maxima Check Engine Light Reset

At Larry H. Miller Nissan Mesa, we recommend a full diagnostic before any reset. Our technicians identify the root cause using OEM procedures, replace or repair faulty components with genuine Nissan parts, and then clear codes only after verifying the repair’s success. Choosing dealership service delivers transparency — you receive an itemized estimate, a clear explanation of repairs, and documentation for warranty protection. We also offer service financing so you can proceed with critical repairs immediately and pay over time. For transparency and long-term reliability, trust us to complete the repair and reset, not just clear the light. To book, schedule appointment and view our latest service specials.
