2026 Nissan Armada Check Engine Light Codes

The 2026 Nissan Armada commonly reports codes that point to oxygen sensor faults (P0135/P0138), catalytic efficiency (P0420), misfires (P0300–P0306), fuel trim issues (P0171/P0174), and evaporative system leaks (P0442). In Mesa, AZ, Larry H. Miller Nissan Mesa is experienced with these specific codes on Armada models and explains the cost implications of delay: an untreated O2 sensor or fuel trim problem can degrade fuel economy and lead to costly catalytic converter replacement; unchecked misfires can cause engine damage and unsafe driving; evaporative leaks reduce efficiency and fail emissions tests. Our technicians use OEM diagnostic procedures to identify the exact cause and present transparent estimates before work begins. Choosing our dealership means faster diagnosis, factory training, genuine Nissan parts, and repair documentation that preserves warranty and resale value. We also offer financing so you can repair now and pay later, and we publish current service specials to lower out-of-pocket costs.

We use OEM scan tools to retrieve and interpret codes, repair root causes with genuine Nissan parts, and then verify repairs by clearing codes and rechecking systems.
