2023 Nissan Murano Check Engine Light Codes

In Mesa, AZ, drivers trust Larry H. Miller Nissan Mesa to interpret and address check engine light codes on the 2023 Nissan Murano. Common codes include P0440 (evaporative emissions leak), P0420 (catalyst system efficiency), P0135 (oxygen sensor heater circuit), and P0300 (random/multiple cylinder misfire). Left untreated, a P0440 can lead to fuel odor and failed emissions tests; fixing it quickly prevents fuel loss and fines. A P0420 often starts with reduced fuel economy and, if ignored, can mean an expensive catalytic converter replacement. Oxygen sensor issues reduce performance and can damage the catalytic converter over time. Misfires hurt drivability and may damage the engine if not repaired promptly. At Larry H. Miller Nissan Mesa we diagnose with OEM-grade scanners, provide clear cost comparisons for repairs, and highlight immediate and long-term savings from addressing codes early. Our certified technicians work efficiently, supported by factory parts and warranty documentation, and we recommend the right repairs to protect your Murano’s lifespan and resale value.

Check Engine Light Flashing

A flashing check engine light on a 2023 Nissan Murano signals active misfire conditions or serious catalytic converter risk and should not be ignored. A flashing lamp often means an engine misfire that can send unburned fuel into the exhaust stream, overheating and damaging the catalytic converter; delaying service increases repair costs and risks being stranded. At Larry H. Miller Nissan Mesa we treat flashing lights as urgent, offering swift diagnostics, honest estimates, and OEM repairs to restore safe operation. We communicate the cost-benefit of immediate repairs and how doing work with certified Nissan technicians preserves warranty coverage and long-term value. Take advantage of our current service specials and ask about service financing to get repairs done now and pay later.

Choosing dealership service assures you of OEM parts, factory-trained technicians, and full transparency on the work performed; we provide written estimates, parts warranties, and genuine Nissan components to protect performance and longevity. Resetting is part of our diagnostic closure process, and we always test-drive and re-scan to confirm the problem is resolved.
